Collagen or Corneal cross linking is a safe procedure used to halt the progression of Keratoconus. During this 60 minute procedure riboflavin (Vitamin B) eye drops are applied to the eye as it is exposed to ultraviolet light.
Collagen cross linking effectively stiffens the cornea and prevents the progressive “coning” of the cornea that is characteristic of Keratoconus. Not only does it prevent worsening of Keratoconus, but 50% of people may experience an improvement in the shape of their cornea. Select patients may further benefit from a combined collagen cross linking procedure with a concurrent laser procedure.
Patients with moderate Keratoconus may benefit from treatments that reduce astigmatism. Intraocular Collamer Lenses such as the Visian ICL or Refractive Lens Exchange with special Toric intraocular lenses are treatments offered at the Herzig Eye Institute.
Advanced Keratoconus may require an outpatient procedure called a corneal transplant or keratoplasty, where part of the cornea is replaced with corneal tissue from a donor. A corneal transplant can restore vision, reduce pain and improve the appearance of a damaged or diseased cornea. Most corneal transplant procedures are successful, but corneal transplants carry a small risk of complications, such as rejection of the donor cornea.
