What are Scleral Lenses?

ScleralLens-Diagram-dark

Scleral contact lenses are rigid gas permeable lenses with an extra-wide diameter. As opposed to traditional contacts, scleral lenses vault over the entire cornea, leaving a gap between the lens and the corneal surface before coming to rest on the white part of your eye (your sclera).

Their unique design has taken scleral lenses to the top of the charts for ultimate wearing comfort, healthy eyes, and excellent vision for people of all ages.

They are custom-fit to your eye and are perfect for those with hard-to-fit eyes, astigmatism, keratoconus, severe dry eye, or for those simply seeking more comfort when wearing contact lenses.

What Are The Advantages Of Wearing Scleral Lenses?

With scleral lenses, you’ll experience consistently clear vision—even if you have an irregular cornea. Here are some of the benefits provided by scleral lenses:

  • Their super-size diameter ensures that they stay centered and stable on your eye, which also prevents them from popping out easily, even if you play sports or lead an active lifestyle.
  • They are made up from high quality, durable materials to last for the long haul.
  • The large size of the lens protects your eyes from debris, dust, and allergens, providing a perfect solution if you suffer from eye allergies.
  • They are composed of highly breathable gas permeable material, which ensures that ample oxygen reaches the eye, leading to healthy eyes and comfortable lens wear.
  • These lenses have a pocket that fills with moisturizing tears. This wet, lubricating cushion leads to a very comfortable wearing experience, as well as healthier eyes.

Ready to say goodbye to all those contact lenses that felt uncomfortable and didn’t give you sharp vision?

We are proud to offer Zenlens™ scleral lenses in our Rockville Centre Long Island practice. Scleral lenses in general have made massive inroads into the contact lens market as they offer some very important benefits over traditional contact lens technology. Scleral lenses vault over the eye and sit on the white part, or the sclera of the eye. This design is superior for three reasons.

  1. The vault design means that patients with irregular shaped corneas from Keratoconus, corneal scarring, or post surgery have an option that both corrects vision more effectively and increases comfort.
  2. The vault design is a drastic improvement for patients with dry eyes, as the vault creates a reservoir for tears to naturally maintain lubrication.
  3. Scleral lenses large design minimizes movement which means less irritation from movement in the eye and sharper vision.

Who Wears Scleral Lenses?

Sclerals-Sqr-Row-2_1280x853

Some wear them for increased comfort, while others choose sclerals because specific eye problems prevent them from wearing regular contact lenses or glasses.

Scleral lenses are extremely helpful in managing the following conditions:

Dry Eyes: For people with gritty, itchy and dry eyes, wearing traditional contact lenses are an added irritation. In contrast, the tear reservoir between the back of the scleral lens and the cornea, the front surface of the eye, allows your eyes to remain moist and comfortable all day long. This makes scleral lenses ideal for those with dry eye syndrome.

Hard-to-Fit Eyes: Those with irregularly shaped cornea, whether due to natural causes, an eye condition (i.e. keratoconus), or complications following surgery (such as LASIK), can at times develop vision problems that cannot be corrected using glasses or soft contact lenses. In such cases, scleral lenses provide a more comfortable, secure fit, and sharper vision.

Scleral lenses are particularly useful for managing these eye conditions:

  • Keratoconus
  • Astigmatism
  • Dry Eyes
  • Giant papillary conjunctivitis (GPC)
  • Post-refractive surgery (i.e. LASIK, PRK)
  • Presbyopia

Whatever your case, we welcome you to call Dr. Shane Galan to discuss your needs and assess whether scleral lenses are a suitable and effective solution for your unique case.

Learn More about Scleral Lenses | FAQ

medical-plus medical-plus How do Scleral Lenses Help with Dry Eye Syndrome?

Scleral lenses tackle three factors simultaneously: they provide vision correction, they protect the eye, and they serve a therapeutic purpose by lubricating the eye. 

By filling the bowl of the lens with unpreserved saline solution prior to inserting it in the eye, you ensure that your eyes are always in a hydrated and comfortable environment. This provides relief from unpleasant dry eye symptoms such as pain, discomfort, eye redness, and itchiness while providing sharp, clear vision.

medical-plus medical-plus Why Do Scleral Lenses Offer Superior Comfort?

Scleral lenses are custom-fit to each person’s unique eye shape, corneal curves, and contours, providing unparalleled comfort. Their size and shape also ensure stability.

To design the lenses, Dr. Shane Galan will take exact measurements of your cornea through a process called corneal topography. This process ensures that your personal pair of scleral lenses allows the right amount of light in and sits stably on the eye, thus offering superior vision, all-day ocular hydration, and increased comfort. 

If other contact lenses haven't worked for you, don’t despair — you may be a candidate for scleral lenses. Talk to Dr. Shane Galan to determine your best course of action.

medical-plus medical-plus Does Insurance Cover Scleral Lenses?

When it comes to scleral lenses, every insurance company is different. Some cover the eye exams and custom fitting, but not the actual lenses. Others may cover a portion of the cost or 100% of the cost, but only if other treatment methods have been exhausted. It’s important that you consult with your  insurance provider to understand the particulars of your scleral lens coverage.

It is our strong belief that one’s quality of life is profoundly associated with one’s vision. Vision problems, whether due to keratoconus, LASIK, ocular trauma corneal irregularities, or dry eye syndrome, affect all aspects of a patient’s life.

Relieve your discomfort by scheduling a consultation with Dr. Shane Galan and we’ll help you find the best solution for your condition and lifestyle.

Orthokeratology

ortkok-children-slideshow

Dr. Galan feels extremely passionate about the benefits of Ortho K for the following reasons:

  • Ortho K is the most effective method of reducing the progression of myopia in children.
  • Ortho K leaves the child glasses and contact lens free during the day, which improves visual performance in school and sports and is a huge boost in their self esteem.
  • Because your child is glasses and contact lens free during the day they are at less of a risk of sports related eye injuries which effect 40,000 children per year.

What is OrthoK

Orthokeratology, commonly called ortho-k, is a method used to correct myopia (nearsightedness) by wearing rigid gas permeable contact lenses overnight, so that no vision correction is needed during daytime hours.

Gas permeable (GP) lenses specialized for ortho-k are inserted at bedtime and worn as you sleep. Throughout the night, the lenses reshape your cornea gently so that your vision becomes clear on the following morning. The correction is temporary, and ideally no eyeglasses or contact lenses will be needed on the next day or two. In order to maintain sharp visual acuity on a daily basis, you need to wear the ortho-k reshaping lenses every night.

Kids Playing Ball Blue Sky 1280x853

Candidates for Ortho-K

Ortho-k is very suitable for nearsighted people who are not appropriate candidates for vision correction surgery, such as children. Individuals of all ages with healthy eyes can try ortho-k, namely because it can be discontinued at any point without permanent effects to the eyes.

People who require vision correction and engage regularly in sports or work in extremely dusty, dirty environments will also appreciate the convenience of ortho-k.

Dark Hair Dark Eyed Girl 1280x853

Vision Results from Ortho-k

Success rates for ortho-k are generally higher for more mild vision prescriptions. The ideal goal is to provide 20/20 vision without any need for eyeglasses or contacts during the day.

According to FDA trials conducted on both CRT and VST lenses, more than 65% of ortho-k patients were provided with 20/20 visual acuity. A whopping number of more than 90% of ortho-k patients achieved 20/40 vision or better (this is the legal requirement for driving without vision correction in most states). Consult with your eye doctor to find out if your vision prescription is within range for successful ortho-k treatment.

How Does Ortho-k Feel?

Although some people have trouble wearing regular gas permeable contact lenses during the day, ortho-k GP lenses are worn while sleeping – so discomfort and awareness of the lenses in your eyes is generally not an issue.

Is Ortho-k expensive?

Professional fitting for ortho-k requires a series of visits to your eye doctor. A number of pairs of contact lenses are also generally needed. GP lenses that are special for ortho-k are more costly than standard contacts. In sum, the fees for ortho-k add up to a higher total than regular contact lenses.

LASIK after Ortho-k

Refractive surgeries, such as LASIK, are possible after treatment with ortho-k lenses. Yet because ortho-k works to reshape your cornea, you are required to stop wearing the lenses for approximately several months before undergoing LASIK. This allows your eyes to return to their original shape.

It’s important to inform your LASIK surgeon if you’ve been wearing ortho-k lenses, and you will be advised as to how long of a wait is necessary before having the laser procedure.

Scleral Lenses and Their Benefits

Custom designed scleral lenses help patients with corneal irregularities achieve dramatic improvements in visual acuity and comfort. The scleral lenses’ oxygen permeable fluid-filled chamber protects the eye as it provides it with the moisture and oxygen it needs to stay healthy. This makes scleral lenses fantastic for promoting the healing of the cornea.

The many benefits associated with scleral lenses render them a popular and satisfying choice for patients with corneal irregularities desiring clear and comfortable vision.


Which Corneal Conditions Can Scleral Lenses Benefit?

  • Keratoconus/Keratoglobus
  • Post LASIK/RK/PRK Ectasia
  • Post PK/INTACS/DMEK/DALK/DSAEK, Etc.
  • Post Corneal Cross Linking

Case Studies

Scleral Lenses Following a Corneal Transplant

Patients with Keratoconus or corneal transplants can see clearly by wearing scleral lenses; they are the safest and best way to correct vision for irregular astigmatism. Following a corneal transplant, the cornea should not be touched with a contact lens. This makes scleral lenses the optimal solution, as they vault over the cornea without touching it directly.

John came to Scleral Lenses & Keratoconus Center At Diamond Vision seeking a solution for his Keratoconus, which affected both his eyes. He had recently undergone a corneal transplant and had a corneal graft for his Keratoconus.

In order to improve John’s visual acuity, Dr. Shane Galan did the following:

  • He took a topography reading of 11,000 points on each cornea and then designed the lens to individually match all 11,000 points of the patient’s corneas. Because he had a corneal transplant, it was crucial that the lens not touch any part of the graft to ensure maximum comfort.
  • He used OCT images to measure the microns between the back surface of the scleral lens and the front surface of the cornea to ensure a healthy graft while wearing the contact lenses.

As a result, John was able to achieve 20/25 vision in both eyes. He now has clear, comfortable vision all day and is very pleased with the scleral lenses he was fitted for at Scleral Lenses & Keratoconus Center At Diamond Vision.

Post-LASIK Complications +

While LASIK surgery has a high success rate, some patients come out of the surgery with imperfect vision. Debbi is one of the many cases we’ve seen at our practice.

Her LASIK surgery results left her with poor vision. Her LASIK surgeon recommended an enhancement procedure to improve her vision, which led her to undergo subsequent LASIK surgeries. Unfortunately, these attempts left her with extremely poor vision in each eye, and Debbi was desperate to find a solution to her vision problems.

Debbi arrived at Scleral Lenses & Keratoconus Center At Diamond Vision after hearing that we specialize in helping people achieve clear vision following poor LASIK results. Dr. Shane Galan examined Debbi’s eyes and found that she had a very high prescription and irregular astigmatism following her surgery.

Her best option was to wear scleral lenses as they would correct her astigmatism, farsightedness and were perfectly safe for her corneas, which after multiple surgeries, were scarred.

Since getting fitted for her custom-designed scleral lenses, Debbi is absolutely thrilled with how sharp and comfortable her vision has become.





Post-RK Surgery Complications +

Many patients underwent Radial Keratotomy (RK) surgery to correct myopia and astigmatism during the early stages of refractive surgery. Because of the aggressiveness of the procedure, those having undergone RK surgery can be left with some refractive error in the form of nearsightedness, farsightedness, or (irregular) astigmatism. Those with irregular astigmatism experience blurred, distorted vision loss which cannot be corrected with glasses. It is among the more serious and frequently occurring complications following corneal refractive surgery.

Matthew, a 52-year-old teacher, underwent bilateral RK surgery in 1995. Though the initial results were positive, within two years his vision deteriorated. He developed corneal ectasia, and complained of blurred vision, discomfort, and red eyes when wearing contact lenses.

The slit lamp examination revealed damaged corneas which had severe staining along the incision lines and around the cornea at the limbus. This was a result of the fit of the GP lenses he was wearing at the time. They were touching the anterior elevations of the cornea and did not allow for enough tear exchange.

Fitting a scleral lens was the best option to treat Matthew’s damaged corneas, alleviate discomfort and improve his vision.

At the one-year visit, the patient improved both visual acuity and quality. The fitting of a well-designed semi-scleral GP contact lens filled with a saline solution created a healthy environment behind the lens, which in turn allowed the cornea and limbus to heal. The scleral lenses also helped protect the RK incisions from further abrasions caused by blinking.

As this case demonstrates, patients having developed irregular corneal surfaces following refractive surgery can benefit from a customized scleral contact lens design to improve their wearing comfort and vision.

Ishihara Color Test

Ishihara Color Test Instructions

Plates 1 – 17 each contain a number, while plates 18 – 24 contain one or two wiggly lines. To pass each test you must identify the correct number, or correctly trace the wiggly lines.

The Ishihara Color Test for Color Blindness

The test is used to identify which colors you are able to identify as well as calculate whether your vision is color deficient in any specific pattern. While the most common form of color blindness is red and green, this test is used to assess other, less common forms of color blindness and gauge the severity as well.

The Ishihara color test is used at our Long Island office to help patients who are seeking to start a career as a police officer, firefighter, or possibly even a pilot in the airforce.

 

Scleral lenses and Your Insurance Provider

When vision starts to become blurry, the immediate solution is to see an eye doctor and purchase a new pair of eyeglasses or contact lenses. In some cases, a person may elect for LASIK surgery, which comes at a much higher price tag.

On rare occasions, a patient may not benefit from wearing standard eyeglasses or contact lenses and is not a candidate for LASIK. These “hard-to-fit’ patients require a more advanced form of treatment like scleral lenses in order to restore their vision to normal. When patients discover they require more advanced vision correction, they have to face new challenges like adjusting to their new eyewear and, more pressing, the additional costs. We’ve put together some brief tips below to help our scleral lens patients take advantage of their insurances to reduce the burden and achieve visual success.

Medical Insurances & Scleral Lenses , New York

While our vision is vital for daily activities, many medical insurances are very restrictive in how they cover any service related to eyewear. Although medical insurances are used for specific eye care services, purchasing eyewear is often not covered — not even partially. Our practice can review with you the specific details regarding your medical insurance, and whether or not you can expect coverage for a pair of scleral lenses. In general, medical insurances are best used towards the eye exams and diagnostic measurements.

Vision Insurances and Scleral Lenses in , New York

Contrary to medical insurance, vision insurance plans are meant to reduce the costs for eyewear purchases. For some of our patients who have vision insurance with a contact lens plan, such as through EyeMed or VSP, a large portion of their scleral lenses will be covered. Please keep in mind that vision insurance policies differ. How much vision insurance will cover a specialty contact lens like scleral lenses is never concrete. Also, the experience of one patient may be totally different from the outcome of another patient’s experience.

This is why we recommend patients to schedule a consultation at our practice. We’ve seen many patients benefit a lot from their vision insurance plans, and we’ve guided numerous patients on how to maximize their coverage. Ultimately, we want our patients to enjoy the best possible vision for their eyes, and scleral lenses are often the solution.

One of the major reasons keratoconus patients and others with corneal irregularities come to our practice is precisely for our knowledge, experience, and expertise. Each specialty contact lens consultation will assess what are your visual needs and budget to develop the perfect pair of contacts. If you’re looking for scleral lenses and want to learn how your insurances can provide you coverage, call us today or schedule a consult online.

Shane M. Galan OD

Dr. Shane Galan was born and raised in Rockaway Beach and Oceanside NY.  He graduated from SUNY Albany in 1991 and The New England College of Optometry in 1996.  In 1997, Dr. Galan completed his residency at the Northport VA Hospital and has owned Diamond Vision since 2000.  Dr. Galan is married to his wife Amy, and has two children (Hunter and Alexa), and adopted the world's cutest dog named Ozzie.

Dr. Galan has continued his education in optometry to specialize in contact lenses. While most optometrists can fit standard soft lenses for patients who are nearsighted, have a slight astigmatism, or presbyopic, very few eye doctors develop expertise in helping patients with corneal disease.  Although in many practices, the standard protocol is to use rigid gas permeable lenses (also known as RGP's),  Dr Galan has expanded his practice with additional contact lenses for greater variety and ensuring his patients have the comfort and visual clarity they need. The most commonly fitted and preferred of these specialty contact lenses are called scleral contact lenses.

In addition to helping patients with corneal disease, Dr. Galan is also very passionate about helping children manage their myopia  (also known as nearsightedness ) Dr Galan designs custom-made contact lenses that may prevent the children's myopia (nearsightedness) from progressing into a higher prescription. Although myopia management has been well-researched over the past 30 years,  proving that eye disease is closely linked to high prescriptions, unfortunately, many eye care practitioners still continue to prescribe glasses to children, which do not slow the progression of myopia.

Dr. Galan decided to help educate parents about myopia, and its progression.  Utilizing the correct myopia management treatments such as Orthokeratology, soft multifocal contact lenses, and atropine can effectively keep a child's eye health and prescription stable. Dr. Galan continues to build his practice with modern technology combined with the latest techniques in the field of optometry so every patient will be guaranteed a lifetime of good eye health & clear vision.

Dr. Galan and the entire staff look forward to meeting you and your family. We provide an atmosphere that is warm and caring. We take the time to listen to all of your needs and concerns and will address all of them. This is why most of our patients are referred by family and friends than any other source.


Our Doctor Can Diagnosis and Treat Keratoconus

Your cornea is the transparent, outer lens of your eye, and it typically has a smooth dome shape. Keratoconus describes a condition in which the corneal structure isn’t strong enough to maintain a healthy ball shape.

Meet with our Keratoconus Specialist in Long Island, New York to define your eye's condition and ways for treatment.

As a result, the cornea bulges outward into more of a cone. Our professional optometric team at our eye care clinic is knowledgeable about how to diagnose and treat keratoconus.

Keratoconus is rare, with an estimated one person out of every 2,000 having the condition. It generally appears in the teenage years and can progress slowly or rapidly.

Keratoconus also runs in families, so if you or your children are at risk, it’s advised to contact us for a thorough eye exam.


Causes of Keratoconus

Your cornea is held in place by very small collagen fibers. When they are weakened and too fragile, they aren’t able to preserve the round shape of your cornea.

A reduction in the protective antioxidants of your cornea, which act to destroy damaging by-products made naturally by corneal cells, is what causes keratoconus.

In addition to genetics, some types of eye injuries may increase your chance of being diagnosed with keratoconus.

Specific ocular diseases, such as retinitis pigmentosa, vernal keratoconjunctivitis and retinopathy of prematurity, as well as some systemic conditions (Down syndrome, Ehlers-Danlos syndrome, Leber's congenital amaurosis and osteogenesis imperfecta) are also associated with this corneal abnormality.


Our Keratoconus Specialist in Long Island, New York has years of experience identifying the various levels of keratoconus and other corneal conditions.

Man Smiling Black Glasses 1280×480

Symptoms of Keratoconus

When the shape of your cornea begins to bulge, it alters your eyesight in two different ways. As the cone shape forms, your normally smooth corneal surface becomes wavy, called irregular astigmatism. Additionally, as your cornea expands, vision becomes increasingly nearsighted. Focusing becomes impossible without eyeglasses or contact lenses. Usually, the problems begin in one eye and develop later in the other eye too.

Typically, patient’s eyeglass prescription will change often as the vision becomes worse and contact lenses will be difficult to wear due to discomfort and improper fit.

When keratoconus become more severe (which usually takes a long time however on occasion can happen rather quickly), the cornea can begin to swell and form scar tissue. This scar tissue can result in even further visual distortion and blurred vision.

Altogether, these changes can create the following symptoms:

  • Blurred vision
  • Streaking of lights
  • Halos around bright lights at night; glare
  • Sudden change of vision in only one eye
  • Objects appear distorted, both near and distant
  • Double vision from just one eye
  • Triple ghost images

Advanced Keratoconus 1280×480

How We Diagnose Keratoconus

Our eye doctors will inspect carefully for the signs of keratoconus during your comprehensive eye exam. It’s critical to inform us of any symptoms that you’ve been experiencing. To diagnose the condition, we’ll measure the shape of your cornea. Computerized Corneal Topography is used for this procedure, which takes a picture of your cornea and analyzes it instantly.


Treatment for Keratoconus

The first line of treatment is usually new prescription eyeglasses. If this solution doesn’t help you achieve good vision, then contact lenses will be tried. Rigid, gas permeable lenses are typically prescribed.

As the disease progresses, however, glasses and soft contact lenses may no longer correct vision and soft lenses may become uncomfortable. This is when other forms of vision correction will be recommended.





Gas Permeable and Scleral Contact Lenses

At the more advanced stage of keratoconus rigid gas permeable (RGP) contact lenses, scleral or semi-scleral lenses may be used for increased comfort and visual acuity. Since they are more rigid, RGP and scleral lenses are able to create a smooth, round shape around the cornea, creating a smoother surface for better vision.

Scleral or semi-scleral lenses have a larger diameter which covers the entire cornea and reaches over into the white part of the eye, which is known as the sclera.

Many patients find these more comfortable than regular RGPs and find that they move around less when the eyes move. The main disadvantage of these rigid lenses is that for some, they are somewhat less comfortable than soft lenses and they must be continually refitted as the shape of the eye changes.

Whether it is glasses or contact lenses being used to correct vision, patients will likely have to undergo many tests and prescription changes as their vision needs to change.





Intacs

Intacs are small, surgically implanted plastic inserts which are placed on the cornea to flatten it back to shape. Usually they are able to restore clear vision, with the continued use of glasses. Intacs are often recommended when contact lenses and eyeglasses are no longer able to correct vision adequately. Intacs take about 10 minutes to insert and can delay the need for corneal transplant.





PTK for severe keratoconus

Severe keratoconus may lead to extreme scarring, due to overstretched collagen fibers. If the back of your corneas tears as a result, swelling may occur. It can take months for the swelling to go down, and a large scar is generally created. PTK, a specialized procedure, can smooth out this scar, thereby enhancing contact lens comfort.





Cornea collagen crosslinking

Cornea collagen crosslinking is another therapy that has shown to be effective in slowing the progression of keratoconus. An alternate remedy is called intacs, which are semicircular implants inserted under the surface of the cornea to flatten the bulging cone shape and give better vision.





Cornea Transplant

As a last resort, a cornea transplant may be performed. During this procedure, the center of your cornea will be removed and replaced with a donor cornea. The new cornea is stitched into place, and you’ll need to wear contact lenses for adequate vision after the surgery.





Dangers of LASIK and Keratoconus

LASIK can potentially weaken the cornea of anyone who suffers from keratoconus, making it a dangerous procedure. If this happens, your vision will become substantially worse. Even if your keratoconus is mild, LASIK is not an option.

Our Keratoconus Specialist in Long Island, New York is happy to meet with you for a 1-on-1 consultation to get you back on the path to reaching clear vision.

Color Blind Testing For The US Military

Being color blind can limit your choices of MOS, the US military currently uses either the Farnsworth Lantern Flashlight (FALANT) test or Ishihara test, with different branches having different thresholds. While there are options for the colorblind in the US military, such as combat arms, supply, military police, and administrative jobs, there are severe limitations for many military career tracks. Because color is used to identify wiring, maps, and many other elements of a job, the US military places restrictions for those that fail to meet the color vision threshold for that service branch and job requirement.

Color Blind Testing For NYPD

The NYPD requires that police officers pass a color vision test. The first test is the Ishihara test if the candidate fails the Ishihara test then they are required to pass the Farnsworth D15 test.

Important Note: The information presented is accurate to the best of our knowledge, however requirements for the FAA/TSA/US Military/FDNY/NYPD do change occasionally. At Diamond Vision, we respect the men and women serving our country and communities and try our hardest to provide the highest quality eye care services to our pilots, service men and women, and first responders.

What are Scleral Lenses?

ScleralLens-Diagram-dark

Scleral contact lenses are rigid gas permeable lenses with an extra-wide diameter. As opposed to traditional contacts, scleral lenses vault over the entire cornea, leaving a gap between the lens and the corneal surface before coming to rest on the white part of your eye (your sclera).

Their unique design has taken scleral lenses to the top of the charts for ultimate wearing comfort, healthy eyes, and excellent vision for people of all ages.

They are custom-fit to your eye and are perfect for those with hard-to-fit eyes, astigmatism, keratoconus, severe dry eye, or for those simply seeking more comfort when wearing contact lenses.

What Are The Advantages Of Wearing Scleral Lenses?

With scleral lenses, you’ll experience consistently clear vision—even if you have an irregular cornea. Here are some of the benefits provided by scleral lenses:

  • Their super-size diameter ensures that they stay centered and stable on your eye, which also prevents them from popping out easily, even if you play sports or lead an active lifestyle.
  • They are made up from high quality, durable materials to last for the long haul.
  • The large size of the lens protects your eyes from debris, dust, and allergens, providing a perfect solution if you suffer from eye allergies.
  • They are composed of highly breathable gas permeable material, which ensures that ample oxygen reaches the eye, leading to healthy eyes and comfortable lens wear.
  • These lenses have a pocket that fills with moisturizing tears. This wet, lubricating cushion leads to a very comfortable wearing experience, as well as healthier eyes.

Ready to say goodbye to all those contact lenses that felt uncomfortable and didn’t give you sharp vision?

We are proud to offer Zenlens™ scleral lenses in our Rockville Centre Long Island practice. Scleral lenses in general have made massive inroads into the contact lens market as they offer some very important benefits over traditional contact lens technology. Scleral lenses vault over the eye and sit on the white part, or the sclera of the eye. This design is superior for three reasons.

  1. The vault design means that patients with irregular shaped corneas from Keratoconus, corneal scarring, or post surgery have an option that both corrects vision more effectively and increases comfort.
  2. The vault design is a drastic improvement for patients with dry eyes, as the vault creates a reservoir for tears to naturally maintain lubrication.
  3. Scleral lenses large design minimizes movement which means less irritation from movement in the eye and sharper vision.

What Others Are Saying About Us

Who Wears Scleral Lenses?

Sclerals-Sqr-Row-2_1280x853

Some wear them for increased comfort, while others choose sclerals because specific eye problems prevent them from wearing regular contact lenses or glasses.

Scleral lenses are extremely helpful in managing the following conditions:

Dry Eyes: For people with gritty, itchy and dry eyes, wearing traditional contact lenses are an added irritation. In contrast, the tear reservoir between the back of the scleral lens and the cornea, the front surface of the eye, allows your eyes to remain moist and comfortable all day long. This makes scleral lenses ideal for those with dry eye syndrome.

Hard-to-Fit Eyes: Those with irregularly shaped cornea, whether due to natural causes, an eye condition (i.e. keratoconus), or complications following surgery (such as LASIK), can at times develop vision problems that cannot be corrected using glasses or soft contact lenses. In such cases, scleral lenses provide a more comfortable, secure fit, and sharper vision.

Scleral lenses are particularly useful for managing these eye conditions:

  • Keratoconus
  • Astigmatism
  • Dry Eyes
  • Giant papillary conjunctivitis (GPC)
  • Post-refractive surgery (i.e. LASIK, PRK)
  • Presbyopia

Whatever your case, we welcome you to call Dr. Shane Galan to discuss your needs and assess whether scleral lenses are a suitable and effective solution for your unique case.

medical-plus medical-plus How do Scleral Lenses Help with Dry Eye Syndrome?

Scleral lenses tackle three factors simultaneously: they provide vision correction, they protect the eye, and they serve a therapeutic purpose by lubricating the eye. 

By filling the bowl of the lens with unpreserved saline solution prior to inserting it in the eye, you ensure that your eyes are always in a hydrated and comfortable environment. This provides relief from unpleasant dry eye symptoms such as pain, discomfort, eye redness, and itchiness while providing sharp, clear vision.

medical-plus medical-plus Why Do Scleral Lenses Offer Superior Comfort?

Scleral lenses are custom-fit to each person’s unique eye shape, corneal curves, and contours, providing unparalleled comfort. Their size and shape also ensure stability.

To design the lenses, Dr. Shane Galan will take exact measurements of your cornea through a process called corneal topography. This process ensures that your personal pair of scleral lenses allows the right amount of light in and sits stably on the eye, thus offering superior vision, all-day ocular hydration, and increased comfort. 

If other contact lenses haven't worked for you, don’t despair — you may be a candidate for scleral lenses. Talk to Dr. Shane Galan to determine your best course of action.

medical-plus medical-plus Does Insurance Cover Scleral Lenses?

When it comes to scleral lenses, every insurance company is different. Some cover the eye exams and custom fitting, but not the actual lenses. Others may cover a portion of the cost or 100% of the cost, but only if other treatment methods have been exhausted. It’s important that you consult with your  insurance provider to understand the particulars of your scleral lens coverage.

It is our strong belief that one’s quality of life is profoundly associated with one’s vision. Vision problems, whether due to keratoconus, LASIK, ocular trauma corneal irregularities, or dry eye syndrome, affect all aspects of a patient’s life.

Relieve your discomfort by scheduling a consultation with Dr. Shane Galan and we’ll help you find the best solution for your condition and lifestyle.

In medicine, there are conditions that are not treated by general practitioners. Ideally, when a particular condition is severe or a sort of complication arises, general practitioners often refer their patients to experts referred to as specialists. This is not done because the doctor doesn’t understand the condition but because it deserves the attention of an expert for the right medical care.

In optometry, there are eye doctors who fit specialty contact lenses, even though many optometrists do not know much about it or prefer not to fit them. Broadly speaking, any general care optometrist or eye doctor can check for eye diseases and disorders, write the perfect prescription for new glasses, and teach patients how to put on contact lenses in a healthy fashion. Most people will be satisfied with this general care, but there are individuals with corneal irregularities that disrupt this traditional eye care practice. These “hard-to-fit” contact lens patients, for instance, are not candidates for wearing standard contact lenses and struggle with standard prescription eyeglasses.

Are Your Eyes Hard To Fit?

Are Your Eyes Hard To Fit?

Do you have trouble wearing contact lenses that they are painful or constantly uncomfortable? You may fall under the category of a hard to fit patient. However, most hard-to-fit patients are often told they simply can’t wear contact lenses or presented with gas permeable lenses for a solution. Their eye condition makes contact lens wear challenging, to put it simply.

    The Following Conditions Are The Major Culprits In Such Cases
    • Astigmatism
    • Dry eyes
    • Giant papillary conjunctivitis (GPC)
    • Keratoconus
    • Post-refractive surgery like LASIK
    • Corneal irregularity or corneal dystrophy
    • Post-Corneal Transplant

    Any of these problems will typically require advanced care beyond the scope of the standard general care optometrist.

    Our optometrist has has taken an interest and developed a specialty contact lens focus to bring hard-to-fit patients relief no matter what sort of eye condition they have. Dr. Shane Galan of Scleral Lenses & Keratoconus Center At Diamond Vision welcomes all types of patients from children to adults who seek advanced contact lens solutions.

Whether someone needs a pair of eyeglasses, standard contact lenses, or specialty contact lenses, our aim is to bring your vision back into focus so you can live comfortably.

    While eye doctors start out as general care optometrists, some decide to specialize in other fields after years of study & practice. Occasionally, some optometrists develop this niche early on and can help fit hard to fit contact lens patients with difficult eye conditions. However, nearly all specialty contact lens eye doctors are optometrists and do not perform eye surgery, since numerous years of analyzing patients with different eye conditions and correcting their vision through custom-tailored contact lenses requires a level of commitment that most surgeons avoid.

    In addition to their years of experience treating different patients of various eye conditions, our eye doctor uses modern contact lens technology to help diagnose and measure the health of the cornea — a vital piece of equipment for custom contact lens design.

    Dr. Shane Galan has researched more about the latest technology in contact lenses and options for treatment than other eye doctors to ensure every patient receives a quick, comfortable fit. At Scleral Lenses & Keratoconus Center At Diamond Vision in Long Island, New York, we aim for a minimal number of trial fits, so every patient can quickly return to living their lives.

    How Do Specialty Contact Lenses Treat Your Eye Conditions?

    How Do Specialty Contact Lenses Treat Your Eye Conditions?

    If you have any corneal irregularity or visual disorder that prevents the use of contact lenses, schedule a consult with Dr. Shane Galan. The first step of any treatment is the diagnosis, which requires an eye doctor to review your medical health, analysis and ultimately devising a plan to treat the challenging eye conditions.

    Our optometrist will start a consultation using diagnostic tools, digital imaging, and corneal topography to produce high-resolution images of your eye. Details of the surfaces of your eye, the cornea, and even the optic nerve will be captured and Dr. Shane Galan will create a visual solution for your specific corneal problem. The most common specialty contact lens used are Scleral lenses. Ortho-K lenses are typically worn by children for myopia control or adults who want an alternative to discuss.

    Scleral Lenses

    These are large diameter gas permeable contact lenses that rest on the sclera and create tear-filled vault over the cornea. By doing this, the lenses are able to functionally replace irregular cornea with a perfectly smooth optical surface to correct vision problems. They are sometimes referred to as ocular surface prostheses and take care of such disorders as keratoconus, dry eyes syndrome, corneal ectasia, Steven-Johnson syndrome,

    Furthermore, scleral lenses are also recommended for patients with neurotrophic keratitis, aniridia, microphthalmia, SjÖgren’s syndrome, higher aberration of the eye, pellucid degeneration, injuries to the eyes and surgical complications. Also, the lenses can help people with eyes that are too sensitive for smaller corneal-type lenses like in the case of astigmatism.

    Ortho-K Lenses

    We may also recommend the use of an Orthokeratology (Ortho-k) lens for your vision. These are specially designed gas permeable contact lenses that you wear overnight to correct your eyesight and reduce your dependence on glasses or other contact lenses without any surgical procedure. They are worn at night when you want to sleep and removed in the morning.

    This means that they work on your eyesight while you sleep, gently reshaping the front surface (cornea) so that your vision is better the next day when you wake and remove the lenses. They are also called corneal reshaping lenses. They can correct such refractive problems as near-sightedness, astigmatism, and hyperopia in children. They can also help with presbyopia in some cases.

    A general care optometrist can help with lots of eye problems but when there are complications or you find it difficult wearing contact lenses, an optometrist who specializes in specialty contact lenses is the right eye doctor to consult.
