What is Keratoconus?
Keratoconus is a progressive disease that affects the cornea by causing it to bulge forward resulting in an irregular cone shape, and changing the shape of the cornea brings light rays out of focus. This irregularity of the cornea that makes vision correction with glasses less effective, and other means of correcting vision are often necessary.
The condition can affect one or both eyes and can cause a variety of symptoms including blurred vision, double vision, trouble seeing despite wearing glasses or contact lenses, as well as dizziness, headaches, and sensitivity to light.
Scleral Conatct Lenses
Scleral lenses are large diameter contact lenses that are designed to rest on the sclera (white part of the eye,) and creates a tear reservoir over the cornea. The lens has a uniform curve, acting like a regular cornea and focuses all light to a single point on the retina. Patients with keratoconus, post-refractive surgeries, corneal transplants, corneal scars, high refractive errors, and other eye conditions can find excellent improvement in vision with scleral lens.
Because of the liquid reservoir between the contact lens and the cornea, it can also aid in effectively providing relief for patients with dry eyes who previously were unsuccessful with other dry eye therapies.
