Sorry for late response. Have not checked this sight in a long time. I live in California & I have only read newspaper & technical articles by dr. Hamrah pulls played a podcast by him which stated the treatment plan noted in my input. Confocal microscopy is a staining of the eye followed by a microscope scan which can detect & measure nerve damage I had it done to prove to my eye doctors that the surgery actually did eye damage & was not something else like my imagination. I never had any blurring, just varying degrees of pain over 6 years. The autologous blood eye drops gave me the most benefit in reducing the pain. I felt no burning. Did you try a 20% vs 50% solution. I also use an eye drop nighttime gel in my eye to avoid a dry eye sensation when I sleep. After 6 years, I still get occasional dry eye & some pain some evenings but much better than the first 2 years. I am continuing with gabapentin, autogolous drops, pain medication & periodically googling for any updated medical info.
