Member: Dr. I had LASIK about four years ago and I developed some cell growth beneath my cornea and it keeps coming back. The cells I have were called epithelia cells and keep coming back. Do you have any advice that I could share with my doctor?
Lloyd: You are experiencing a very common complication from LASIK surgery. The outermost layer of cells on the corneal surface is called the epithelium. When the LASIK flap is created, a new pathway for these cells is created. The LASIK flap never heals. As an experienced eye pathologist, I can tell you that the LASIK flap NEVER heals. That means there is a thin layer of corneal tissue resting on the remaining cornea for life. No scar forms because (once again) there is no healing.
This raises two critical points: The LASIK flap remains available to both epithelial cells and germs for the remainder of your life. Secondly, the LASIK flap can be easily dislodged from simple contact with the eye such as a finger poke. Once the flap is lost the eye is in serious trouble. It will require a corneal transplant (a much more serious operation) to regain useful eyesight. Anyone who has had LASIK needs to wear eye protection when outdoors, working in the yard or participating in vigorous activities. These precautions must be followed for a lifetime.
