@bobr1040 hi, this is Rhoda @rckj. Sorry it took me a day to get back to you. Also, if you feel comfortable explaining to me what kind of peripheral pain you have, I might be able to answer your questions better. I have map dot fingerprint corneal dystrophy and have had two surgeries to each eye. I am temporarily stable but showing some signs that may lead to more surgery. I was misdiagnosed for many years until I found a corneal dystrophy specialist. He is really good and compassionate. If you are anywhere near Boston, I highly recommend him. Micheal Raizman, MD at Opthalmic Consultants of Boston. If you aren’t too far away I know an organization that flys patients to medical care free of charge. The surgeries I have had were all debridement plus use of the excimer laser to clear debris and promote healing. Yes, after all surgeries I had excruciating pain. Dr. Raizman explained the issue with opiates. The cornea is filled with nerves but has virtually no blood supply. So taking oral or IV painkillers will never work on the cornea because there is no blood supply to bring it to the cornea. It wasn’t an issue of withholding opiates because of all the current overreaction to opiate use. Patients in pain need should get opiates if they will help. I do, for another serious illness I have. They help with my other illness but not with the corneas. I researched corneal pain and I believe my doctor is right. But, opiates should work on peripheral pain that doesn’t originate in the cornea. All my peripheral pain was referred pain from the cornea so no help there. There are analgesic drops for surgeries and procedures but they can’t be used for post operative pain as they damage and degrade the cornea with any use other than procedures. Bandage lenses help me some as well as several drops that encourage the cornea to heal, plus antibiotic drops. Regarding bandage lens, they have to be carefully fitted and inserted, then kept moist with whatever drop your doctor recommends. Lubricant drops helped me but check with your doctor first. Also any lubricant drop must be preservative free, usually single use containers. I use Refresh Plus. Same brand ointment helped at night. But , yes, the pain was awful due to all those nerves in the cornea and no blood supply to deliver the opiates. I wish I knew what to say. Oh, it also helps to stay in dark rooms and use dark glasses. My doctor gave me dark glasses that fit over my regular glasses, which helped.Regarding peripheral pain, I saw a neuroopthamologist who confirmed, for me, that all the pain came from the cornea, after a series of simple tests. It was awful. I have taken hydromorphone (dilaudid) with minimal effect. I use self and guided hypnosis which helped some. I am a doctoral clinical psychologist who does hypnosis, so had access to those resources. Depending on where you are, I might know someone, if you want to try that. Basically I had to wait for healing. Did they use the laser as it does shorten healing time? Dr Raizman is one of the worlds experts on dystrophy and the laser. I’d be happy to call him for a referral in your area, if you decide to change doctors. Regarding “sand in the eye” feeling, lubrication helped. My doctor also put silicone punctal plugs in both lower lids. It blocks too rapid drainage of tears, keeping the cornea naturally moister. Sad to say, despite all the advice and my doctor warning me about the pain, it is awful and basically I had to ride it out. Dr Raizman kept a close eye on me and adjusted drops, etc. I am hoping you will write back and let me know what helped and what didn’t. I may also have more information on your peripheral pain once I understand what it is for you. All my best wishes and hopes for a speedier relief from pain. Regards, Rhoda.
