Corneal Cross-Linking Patient FAQ

What is keratoconus?
Keratoconus is a non-inflammatory eye condition in which the typically dome-shaped cornea progressively thins and weakens, causing the development of a cone-like bulge and optical irregularity of the cornea. This progressive change in the shape of the corneal causes visual disturbance.

What is cross-linking?
Cross-linking is a minimally invasive, FDA approved, outpatient procedure that combines the use of prescription eye drops, Photrexa® Viscous(riboflavin5’-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 can I expect during the procedure?
After numbing drops are applied, the epithelium (the thin layer on the surface of the cornea) is gently removed. Next Photrexa Viscous eye drops will be applied to the cornea for at least 30 minutes. The cornea is then exposed to UV light for 30 minutes while additional Photrexa Viscous drops are applied.

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.

Does corneal cross-linking require removal of the epithelium?
Yes, your doctor will apply topical anesthesia to numb the eye prior to the removal of the epithelium. This process helps to prepare your eye so that the drug can penetrate the tissue of the cornea to have an effective cross-linking procedure.

Am I awake during the procedure?
Yes, typically you will be awake during the treatment. You may be given a medication to help you relax, and numbing anesthetic drops.

How long does the treatment take?
The actual procedure takes about an hour, but you will be at the office for approximately two hours to allow sufficient time for preparation and recovery before you return to the comfort of your own home.

What can I expect after the procedure?
You should not rub your eyes for the first five days after the procedure. You may notice a sensitivity to light and have a foreign body sensation. You may also experience discomfort in the treated eye and sunglasses may help with light sensitivity. If you

Traditionally, presbyopia, which happens to all of us as we age, has always meant glasses for clear reading vision. It's a condition not even correctable by laser vision correction. Luckily, there is an option. Refractive lens exchange allows patients a clear alternative to reading glasses and is capable of reducing or eliminating presbyopia by using an advanced multifocal intraocular lens.

Keratoconus describes a cornea that weakens as collagen fibers deteriorate, causing the cornea to adapt a cone-like shape. Keratoconus can cause blurred vision, light sensitivity, glares, and decreased night vision. In its early stages, keratoconus may be treated with the use of prescription glasses or contact lenses.  Keratoconus is also one of the most common reasons for corneal transplant, and one of the most successful. call any of our offices and ask to speak to the Vision Correction Surgical Coordinator, or use the contact form below.

It's estimated that a million or more Americans have glaucoma and don't even know it.  People with glaucoma often do not experience any symptoms until they begin losing their peripheral vision. One of the scariest things about glaucoma is that it usually has no symptoms in the early stages, earning glaucoma the name "silent thief of sight." Anyone can be at risk, so it's important to have your vision regularly examined.
