I have worn glasses for nearsightedness and astigmatism since I was eight; I am now 50. Two years ago I had PRK surgery. I'm not sure why now. I was told I would need reading glasses anyway, but it was exciting to think I wouldn't need glasses most of the time. I have suffered from dry eye ever since and had punctal plugs placed in both top and bottom lids to help. I think my vision was over-corrected because nothing is crystal clear at any distance though on sunny days I feel I can see best. Before surgery, maybe ten years ago, an eye dr. told me that I should do exercises looking at beads at various distances along a string held in front of my eyes. He indicated that I could prevent something from going wrong later; I never asked what. Now when I do close work at the computer or reading a book, I very quickly start to see double. The double vision happens at both a far distance and to the letters on the page. It occurs horizontally below the object I'm viewing. I lasts for a good long time. I'm worried and don't know what to do next. Should I see the PRK surgeon again? Should I just see my regular eye dr.? Eye drops seem to dry my eyes out eventually; I use Systane.
You should see a good ophthalmologist for a complete evaluation. You need a refraction to see what the eye prescription is, to determine if you need a change in your glasses' prescription. Uncorrected refractive error can give double vision symptoms. Also ask about Restasis eye drops, which treat the inflammation which causes dry eye; this will allow your eyes to produce their own tears. Restasis is not a steroid, so it is safe for long-term use. Exercises will not help your vision at this age. It is a good idea to continue artificial tears 4 times a day. Systane, Optive, and Blink Tears are good ones.
