Recurrent corneal erosion syndrome (RCES) describes the repeated breakdown of the corneal epithelium caused by loose attachment of the epithelium to the underlying cornea. This often occurs at the site of a previous abrasion. After the abrasion heals, the new epithelium that grows back doesn’t adhere normally, predisposing it to recurrent breakdowns that cause severe eye pain, light sensitivity and watering. Some people have an underlying condition called epithelial basement membrane dystrophy (also known as map-dot-fingerprint dystrophy) that predisposes them to having RCES.

With the use of modern laser platforms, PTK treatments have an ablation profile that is refractively neutral. This means that if you currently wear glasses or contact lenses, your prescription is unlikely to change. Likewise, if you do not wear glasses, this is likely to remain unchanged as well.

At the end of the procedure, your vision will be quite blurry. Vision may be variable for the first week while the surface heals. It will then continue to gradually improve over the following few weeks before it stabilizes.

After the procedure, you will have a protective bandage contact lens placed over the cornea for 3 to 4 days for comfort and to support the regeneration of the new epithelium. Your eyes will be watery, irritated and light sensitive for the first few days after treatment. We recommend that you take a week off work as the eye will be uncomfortable as the surface heals. Most people are able to go back to work and resume normal activities a week after surgery.
