Collagen Cross-Linking Helps Maintain Vision for Keratoconus Patients
Collagen cross-linking is an in-office procedure that strengthens the cornea if it’s been weakened by keratoconus. What’s new and exciting, is the option to prevent vision loss before patients with keratoconus need corrective lens and, even more significantly, to reduce the need for corneal transplants.
Keratoconus tends to be diagnosed among teens and young adults and progresses for 10 to 20 years before slowing. The earlier it can be treated, the better the outcome.
Up to now, treatments have been focused on management of symptoms, often with specialized contact lenses and, if patients don’t see better, then corneal transplants. Magruder Laser Vision is now offering a treatment that, if provided early in the disease, can help maintain better vision.
Keratoconus causes the cornea — the front window of the eye — to be distorted and shaped like a cone, rather than the typical basketball shape. The abnormal shape can cause vision changes, such as light sensitivity, glare and irritation, and can lead to frequent changes in glasses and contact lens prescriptions for nearsightedness.
The cornea contains tiny fibers of protein called collagen, and these fibers help hold the cornea in place and keep it from distorting.
Corneal cross-linking involves removing the front layer of the cornea and administering an eye drop of liquid riboflavin (vitamin B2) to the surface of the eye. Ultraviolent light is then delivered to the eye at differing levels of time and intensity. The eye drop helps the cornea absorb the ultraviolet light and stiffen. The procedure lasts 60 to 90 minutes.
