Dr. Rapoza at Opthalmic Consultants of Boston. Four years ago I had lasik and my wife had PRK. They're busy and the scheduling for checkups sucked, but he was fantastic. You can Google him and read his bio.

It's pricey, but you can use HSA/FSA for it. My wife needed a touchup a year later due to an old scar and this didn't cost extra.

Edit: I should note that OCB has a location in Boston for checkups, but Dr. Rapoza only does surgery in Waltham as far as I know.
