Dr. Knauf was excellent! I had cataract surgery done on just one eye and was concerned with the outcome of my sight given that my other eye did not have a cataract. Dr. Knauf listened to my concerns and recommended a solution that has given me my sight back again. Follow up phone call day of surgery was very much appreciated. Throughout the weeks after surgery, care and concern was shown by Dr. Knauf and his staff. Highly recommend Dr. Knauf!
