The doctor was explaining it verbally without using any aids. As in your diagram, he said there was concentric rings around a center hole, I probably mistook him for meaning a physical hole. The centration of these rings needed to be fairly exact or problems could arise like blurry vision, halos, glare, etc. He said the single vision lens had very little problems. Overall in his 8 years at Gainesville and over 12,000 procedures in his office he was only aware of one patient losing their eye sight after surgery. He said that patient had other problems and was probably not a good candidate for the surgery. When I heard all that, I was confident this would work but wanted the less complicated and went with the single vision lens.
So far so good in my right eye, everything is so much brighter, I never knew whites didn't have an amber tint. I had been in twilight five previous times for various procedures such as cardiac cath and carpal tunnel surgery. This was the most twilight of all, I was nowhere near groggy or in and out of sleep, full awake but yet no pain whatsoever. However, with an oxygen tube in your nose and your face covered except for the hole around the eye, you see nothing and only hear music, they played my choice, which was the Beatles.
