Lumi Thera treatments were not available in the U.S,, so I went to Switzerland for three weeks and received them. At the close of the treatments, I could read one more line on the eye chart! There are no side effects. Now, thankfully, Lumi Thera has been approved by the FDA. There may only be two U.S. locations so far. One is in Garden Grove, CA; I travel 40 miles to it. The retinologist gives a complete eye exam before the starting treatment. I am so excited with Lumi Thera, and hope I have the same result as in Switzerland. 😀 😀 😀
