I will soon be meeting with an opthamologist for the purpose of laser treatment for early glaucoma caused by some meds I was given for a recent head injury. I am told that the treatment causes some pain, and I am wondering what to expect, other than the pain I have presently, which is relieved with some very good OTC drops for dry eyes. Also, I saw a product for dry eyes that was a 'warming mask' and I wonder if anyone has any experience with this type of eye mask, thanks
