Patient verified via Press Ganey

I chose Dr. David Hwang this time, I am a patient with deep myopia, my right eye was hit by a ping pong ball 20 years ago, causing bleeding in the fundus of my right eye, which seriously affected my vision in my right eye, and now the second eye suffers from cataracts, I am very anxious, Dr. Hwang examined my eyes, made a very accurate judgment, and made a very prudent decision to let me do a retinal examination to rule out the possibility of retinopathy, and then decided to do cataract surgery for me, I am very grateful to Dr. Hwang for his patience, careful analysis, and superb medical skills, which relieved my anxiety and was a very pleasant experience.
