What Is a Keratoconus?
Go to Our Treatment Page
Keratoconus is an eye condition in which the cornea becomes progressively thinner and begins to bulge and become cone-like in shape. Keratoconus is characterized by a marked deterioration in vision. Two in 1,000 people are affected by the condition. It can form during adolescence or a person’s early 20s, and often goes undetected for many years. Keratoconus can lead to permanent vision loss if left untreated and may require a corneal transplant.
The following are signs and symptoms of keratoconus:
- Blurry distorted, vision
- Eye strain
- Frequent changes in eyeglass prescription
- Headaches and pain around the eyes
- Eye irritation leading to excessive rubbing of the eyes
- Increased sensitivity to light
- Nearsightedness
- Astigmatism, glare or halos
- Difficulty driving at night
How Is Keratoconus Diagnosed?
To diagnose keratoconus, Dr. Skouras will conduct several tests, including computerized corneal topography, which measures the curvature of the cornea. Permanent vision loss can often be avoided if keratoconus is diagnosed early.
Keratoconus Treatment — Corneal Cross-linking
A revolutionary treatment for keratoconus called corneal cross-linking (CXL) is now available at Skouras Eye & Cosmetic Centre. This non-invasive procedure strengthens the corneal tissue, stops progression of the disease and reverses the bulging of the cornea. Corneal cross-linking is performed by administering a combination of riboflavin eye drops (vitamin B12) and ultraviolet light for 30 minutes, which causes a reaction that strengthens the bonds between collagen molecules within the eye.
Corneal cross-linking is usually performed by removing the outer layer of the epithelium. After applying the riboflavin drops to the cornea, Dr. Skouras exposes the eye to a pre-determined amount of ultraviolet (UVA) light. This light activates the riboflavin, causing a bond between the collagen fibers in the cornea. Corneal cross-linking is safe, effective and fast. A bandage extended-wear contact lens is inserted following the procedure, to allow the epithelium to heal. This bandage contact lens is worn for approximately 72 hours.
Results of CXL tend to improve over a few years, with gradual reversal of the steepening associated with keratoconus.
