Effect of Superficial Keratotomy on Reducing Postoperative Pain Fallowing Conjuctival Flap

Plain-language summary

During conjunctival flap surgery the corneal epithelium is removed and a conjunctival flap is placed on the cornea and after a few weeks the conjunctiva covers the surface of the eye. Complications of this operation are flap retraction, conjunctival inclusion cysts, bleeding, infection and pain. Pain is one of the main complications of conjunctival flap surgery. Two sources are conceivable for pain: 1) conjunctival pain 2) corneal pain, the second of which is the main part of the pain. Numerous methods for controlling corneal pain have been reported in various articles. Eye patches are often recommended for the treatment of corneal abrasions despite the lack of evidence. Recommended analgesics to control corneal scratch pain include nonsteroidal anti-inflammatory drugs (NSAIDs), local anesthetics, and topical cycloplegias. In this article, we are going to review and evaluate a new method called corneal neuorotomy, i.e., corneal nerve endings that inserted radially can be cut to reduce postoperative pain.
