I went to the opthalmologist today to get checked for an eye infection. He said my left lens was dirty. Had me take it out, and put it in a case with some disinfectant. He then added Alcon Supraclens. When I put the lens back in my eye, it burned and stang my eye. I looked at the vial of Supraclens, and it had expired!! The date was May 2003. I called Alcon and they said it shouldn't cause any permanent damage but my eye is still watering after flushing it out with water. Any advice?
