Keratoconus is a progressive eye disorder that causes your cornea to bulge. As a result, your cornea becomes less round, instead taking on a cone-like shape which deflects light away from your retina, creating distorted vision. Keratoconus typically develops during adolescence or your early 20s, and can occur in one or both eyes.
The condition develops due to a weakening of your corneal tissue. Over time, the shape of your cornea will continue to change, resulting in progressively worse vision. In many instances, people with keratoconus will require a new eyeglass prescription every time they undergo an eye exam.
Dr. Daniel Sambursky offers collagen cross-linking, one of the most advanced keratoconus treatments available. You can find out if this treatment is right for you by speaking with Dr. Sambursky in person. Please call (607) 821-4455 today to schedule an exam at our Binghamton office.
As your cornea becomes increasingly cone-shaped, it will result in the development of progressive nearsightedness and irregular astigmatism. This will cause you to experience blurred and distorted vision.
Other symptoms of keratoconus include:
- Light sensitivity
Keratoconus Treatment with Collagen Cross-Linking (CXL)
Collagen cross-linking, also called corneal cross-linking (CXL), is a new procedure approved by the FDA in April 2016. Liquid riboflavin (vitamin B2) is applied to the surface of your eye and an ultraviolet light is used to strengthen the cornea, preventing the progressive bulging that distorts your vision when you have keratoconus.
There are two different corneal cross-linking techniques:
- Epithelium-off CXL -- This method involves the removal of the epithelium (the outer layer of your cornea) to facilitate penetration of the riboflavin into your corneal tissue.
- Epithelium-on CXL -- This method does not remove the epithelium prior to the administration of liquid riboflavin. As a result, the riboflavin must be applied to your eyes for a longer period of time in order to achieve your desired results.
Prior to your procedure, Dr. Sambursky will measure the thickness of your cornea to determine whether you're a suitable candidate for collagen cross-linking. He will also perform a corneal topography to map your cornea and determine the severity of your condition.
Your CXL procedure will typically take 60-90 minutes to complete. Dr. Sambursky will place you in a reclining position. Depending on the technique being used, your epithelium may be removed prior to the application of the riboflavin drops. The ultraviolet light will then be applied for up to a half hour.
You may initially experience some mild eye irritation following your treatment. However, this will gradually subside as the eye and tear film heal over the next few weeks.
What Results Can I Expect from Collagen Cross-Linking?
In general, collagen cross-linking is most effective when performed during the earlier stages of keratoconus, before your cornea has become too cone-like in shape and your vision has become significantly distorted. Clinical studies have found that both techniques achieve a 99% success rate in stabilizing or improving the shape of your cornea. This will help you achieve clearer vision and improve your ability to wear contact lenses.
