I remember before that who got LASIK was Al Martin, Prior to his first season here. He absolutely raved about his improved ability to see the baseball. Dr. D might have bought. Intuitively, and in a vaccuum, he might have hit better than he did in his time here, but with the change in league, home ballpark, coaching/hitting instruction, whether he was already in age decline, etc. etc. etc, who is really to say why he didn't hit better and actually hit worse? It is difficult to isolate the effects of LASIK on the different aspects of visual function as it is (studies are being performed in my field all the time), let alone how those changes in visual function, for better or worse, affect actual baseball performance. Have some more research by a few collegues on that exact subject I home I believe, and I will check once I am off duty.
