If this is the foremost, guru ophth doc who has practiced for years, and he/she likes the "relatively minor change" that this involves, I would have no problem doing the study. The doc is not going to risk their reputation for the study, and 110 eyes is enough that he/she would have found out about complications or glitches by now. 110 does not sound like a lot, perhaps, but this is on top of the thousands the doc has done before. However tricky, it is still a repetitive motor task, and the learning curve is early on, just like flipping a pancake or sewing on a button; our local guru does an eye in 6 minutes flat!

The fact that your doc is going to switch to this when it becomes available is a good sign, too.

It's always a bit scary to think of any procedure, or any study, but it's always fair to ask the doc, "What would you do if it were you/your wife/mother/etc.?" Docs are often careful about not pushing a patient to any particular conclusion, but generally know absolutely what they would do in their own situation, and that can be valuable.
