For the last 2 years I've had to go to the eye DR. for my eyes swelling, itching, and redness. I just went to see him again 2 weeks ago b/c my one eye was completely swelled shut and I had no upper eyelid. It was gross and scary. He gave me Prednisolone Acetate Ophthalmic (eye drops). They are a steriod and should only be used for a couple days not for long term use. ANyway I used them for 4 days to get everything back to normal. Now I'm back to normal and the eye DR. gave me a 2nd prescription for Patanol (eye drops). Those can be used everyday forever i's just like an allergy eye drop. A lot better than visine tears or any other OTC eye drop. My eyes havent swollen anymore and I use the Patonal 2 times a day. It seems to be doing the job.Hope this helps.
