How Scleral Lenses Correct Keratoconus

Scleral lenses are an innovative treatment option for patients with keratoconus and other corneal irregularities. They’re larger than regular contacts and rest on the whites of the eye (the sclera), which allows them to arch over the sensitive cornea, not coming in direct contact with it.

This creates a space between the cornea and the lens which is filled with a saline that creates a new optical surface, resulting in clear vision and a comfortable fit.

Moreover, sclera lenses are ideal for patients with keratoconus because they reduce corneal irritation that can occur during blinking. In many cases, patients are able to avoid corneal transplant surgery due to sclera lenses.
