My vision was at a -8.25. I couldn’t even see my hand 6 inches from my face. Seconds after the surgery I could see an improvement. Minutes later I could see one of the nurse’s faces who was 10 feet away. The next day, I woke up with 90% better vision. It will continue to improve. I was very nervous about the procedure, but Dr. Wang and his staff are extremely nice and caring. I would highly recommend Dr. Wang for any LASIK surgery.
