Your eye doctor should be able to get you some of those 'over all glasses' sunglasses that are made to go on over regular glasses.
Mine gave me a set after cataract surgery last year. They aren't exactly pretty, but they do an excellent job of blocking light coming even from the sides. They wrap around the side to block almost completely.
If your eye guy (or gal) won't give you a set, and you don't already have some[thing], let me know and I'd be happy to mail the ones I have (surgery was in July 2008 so I'm long past needing them).
Best to you; I hope you heal quickly and painlesserly.
EDIT: P.S. What is an 'Eye Plug'?
