CORRECTION
With scleral lenses, we provide vision correction for patients who have corneal diseases, dystrophies, and degenerations (i.e. keratoconus), patients who have corneal scars and irregularities, and patients who have had a corneal transplant or refractive surgery (i.e. LASIK and RK).
COMFORT
Scleral lenses are large diameter rigid gas permeable lenses. Because of their size (14mm to 24mm), they rest on the sclera which is the white part of the eye. Fewer nerve endings means less sensitivity which ultimately means a very comfortable contact lens! Most patients will report that scleral lenses are the most comfortable contact lens they have ever worn even when compared to soft contact lenses.
The common denominator for all of these patients is their corneas are altered in some way. If the cornea does not have a perfect convex or dome shape, vision will be poor through both glasses and traditional contact lenses. So, how can a scleral lens help these patients? Between the scleral lens and the cornea, there is a fluid-filled reservoir. This reservoir fills in all the corneal irregularities and creates a perfectly rounded surface. And, VOILA… most patients report the best vision they have ever experienced!
