I had really poor vision. I had lasik done on one eye, then the other. Initial results were far better than I even hoped for. Over the years it regressed ever so slightly, but I will always be better off than had I not had the procedures.
The expense was the biggest hurdle to getting it done, and making sure I went to someone with experience, good qualifications, and good track record. Now, medical offices offer financing. The interest rate on the medical credit cards is not bad. It is worth paying a higher price to a doctor with an established reputation than to just go with the best advertised price.
