What is keratoconus?
Keratoconus, often referred to as “KC”, is a non-inflammatory eye condition in which the typically round dome-shaped cornea progressively thins and weakens, causing the development of a cone-like bulge and optical irregularity of the cornea. This causes distortion in your vision and can result in significant vision impairment.
Traditional treatment for keratoconus has been limited to surgical options like a corneal transplant or implants into the cornea. But now, there is a new treatment that helps stabilize the cornea and helps slow progression. This office based treatment is call Cross-linking and is now available in our Greensburg office.
What is cross-linking?
Cross-linking is a minimally invasive, FDA approved, outpatient procedure that combines the use of riboflavin eye drops, Photrexa® Viscous, (riboflavin 5’-phosphate in 20% dextran ophthalmic solution), Photrexa® (riboflavin 5’-phosphate ophthalmic solution), and ultra-violet A (UVA) light from the KXL® system for the treatment of progressive keratoconus.
What is riboflavin?
Riboflavin (vitamin B2) is naturally occurring in the body, including the eye. It is a photosensitizer. Riboflavin is non-toxic and is used as an additive in food and pharmaceuticals.
What is ultra-violet A (UVA) light?
UVA is one of the three types of invisible light rays given off by the sun (together with ultra- violet B and ultra-violet C) and is the weakest of the three.
How long does the treatment take?
The actual procedure takes about an hour, but you will be at the offfice for approximately two hours to allow sufficient time for preparation and recovery before you return to the comfort of your own home.
Is cross-linking right for me?
Patients over the age of 14 who have been diagnosed with progressive keratoconus should ask their doctor whether they may be a candidate for the procedure. Call our office to make an appointment and get more information.
