I went to Dr. Coker because a grey spot had suddenly appeared in my right eye (not just a floater). I recently moved to Las Vegas and was anxious to find a 'medical' eye doctor (not someone specializing in Lasik or fitting eyeglasses). I couldn't be more pleased (and relieved) to find Dr. Coker who not only knows the science and has the latest equipment but was very personable and took the time to precisely explain what was occurring. He really cares about his patients. It's also nice that his staff is friendly and helpful - they gave me price ranges for new lenses without trying to sell me. I highly recommend them.
