As some people may know I have Cogans Dystrophy and even more importantly I have Recurrent Corneal Erosion Syndrome or RCE. Less then two years ago I had my eye surgery and spent 6 weeks in a dark room with no windows, lights, or fans. I still have to have lubrication therapy with drops and a antibiotic ointment that I am to use daily. It’s something at this point I can only try to prevent with much care but it will come again at some point in life. Anyway Here is a great site that gives a little more details about what it’s all about. I found it to be helpful!!
