i don't wear glasses but with age related eye fade I can tell you the chart in the better eyesight without glasses by Willian Bates really works well if you do the lessons. Put the chart that comes with the book on a wall. Then mark off 6 feet, 12 feet, and 18 ft or such. Place one hand over one eye and read the lowest line then do the other eye. Go back to 12 feet and do the same then 18 feet. Repeat this five times twice a day and you will get 20/20 vision very fast. It has worked for me very well. My neighbor who had glasses doesn't anymore and she is very thankful I told her about it. Not sure about surgery issues though but it won't hurt.
