If you need cataract surgery, ask Dr. Chiang about the cataract multi-focal lens. I had to wear glasses or contact lenses since I was 18 years old. For the first time since the procedure, I don’t need glasses for reading or distance. It’s really great. Yesterday I had to sew a button on a shirt and was able to thread the needle with no problem. The surgery for the procedure was painless and the recovery time is short. Seeing great at 64.
