I had cataract surgery in one eye. I elected not to have same ophthalmologist do the other eye because my new eye now has a pupil larger than in the other eye (I think from stretching during surgery) and I have a very slight eyelid droop (again from a tool he used). He told me he had trouble dilating my eye prior to surgery (but later on, he denied he said that ?!?). THE GOOD NEWS IS MY DISTANCE VISION HAS DEFINITELY IMPROVED and the surgery was not painful. But, with regard to your question on dry eyes – I use a computer daily for many hours. I use drops (Systane and others). But what I want to mention is the BRUDER EYE PADS. The Dr. suggested them and I find them to be very good. The mask (eye pads) has granules in it; you put it in the microwave for 14 seconds. Then (it cannot be TOO HOT) put them over you eyes for 5 minutes. I think they help and I believe the heat opens the tiny blood vessels in your eyelid which simulates tears. (NOW, I MAY NOT HAVE EXPLAINED THat CORRECTLY, BUT I DO THINK THEY HELP). Best wishes, "GolfandTennis".
