Hello, I am not sure if I can be of any help. First of all apologies for my bad English, as I am not a native speaker. But I too had long-lasting pains and sensations in my eyes and head (and still have but less), before and AFTER my corneal debridement procedure in both eyes. I also went to a neurologist and she found nothing wrong. Then I learned about neuropathy. The nerves in the eyes are probably extremely triggered by the procedures and have been overly sensitive and need to calm down. I did a lot of research and what may help you are opioid pain-relievers. I am not sure if they are allowed in the US, but in the Netherlands, I have been prescribed the opioid with the brand name Tramadol. When I had severe pains and sensitivity (and could not sleep because of it) I took this for the night. After three nights or so I indeed noticed less sensitivity and less pain. I followed this procedure several times. What also is important to recognize that the cornea (and I don't even know about the deeper layers, please investigate) can take forever to heal, even up to one year. In the meantime, all kinds of discomfort can be expected associated with the healing next to the neuropathy. What also somewhat helped me was self-hypnosis/mantra. (In which I was trying to program myself that my eyes are perfect and all functions were just as they should be etc.) Pains one and a half year later seems too long though. Wishing you all the best.
