Hey There,
I haven't had the eye surgery myself. I'm quite pleased with my contacts. But I have a few friends who have. All of them were very postive about it. One of them is a Cacoy Doce Pares player and he spars all the time. I've sparred with him quite a bit since the operation both in gear and without and he, if anything, has gotten quicker.
I'd say if you don't fear infection, then go for it.
