I had routine cataract surgery 5 years ago. My vision was perfect but I immediately experienced severe eye pain. The ophthalmologist said it had nothing to do with the eye surgery. A neurological ophthalmologist said it was nerve damage & prescribe gabapetin & Tylenol. After several months of continuing pain, I came across some medical papers by dr. Pedram Hamrah of Tufts Eye Institute. He noted many ophthalmologists are in denial about problems with cataract surgery which can occasionally lead to nerve damage & pain. He recommends the following course of action: confocal microscopy to determine degree of nerve damage; autologous blood serum drops to accelerate nerve healing; steroid eye drops to help with irritation. I gave that information to my ophthalmologist who then reviewed Dr. Hamrah’s papers & approved that course of action. My nerve damage was verified by the confocal microscope test. The autologous eye drops dramatically reduced my pain in 30 days. I went from a hot burning sand sensation in my eye to one of moderate dry eye. I recommend that people google the research papers of Dr. Hamrah to determine if his recommendations are suitable for them if they are having long term post cataract pain.
