I had cataract surgery three years ago and about a year ago I noticed deterioration of my eye-sight. Thinking that I was going to need glasses, I went to visit Dr Sondheimer to have an eye exam. There is a gray film the develops behind the lenses of the implant and that was what was causing the changes in my eye-sight. He immediately did lazer surgery on the worst of the two eyes and within two days my sight was back to the original post surgery sight. Two days later the other was done. What great service! Thank you
