Lasic (sp) is a possible alternative, if you are otherwise healthy enough to tolerate it. My D-I-L had it done, she's 40, and sees batter than she ever has - had worn glasses all her life.

The mention of multi-focal lenses reminded me of something that I experienced with mine: I had a terrible time walking and working on jobsites with them, and finally went back to single vision lenses; I kept tripping over grade changes, or misjudging a low clearance and trying to take my cabeza off, or I'd reach for something and miss. If I was working on a piece of equipment that required a lot of eye movement and different focal points, I'd get a headache, or make myself dizzy from moving my head around to accomodate them. I still have a pair of bi-focals, but only use them rarely, on work on a bench, like carb work, or such.
