When you say "laser", are you meaning the "RK" type (for nearsighted less than diopter -6, they zap the center of the cornea with the laser) or the LASIK (flap & zap, greater than -6) ?
I had the LASIK 4 yrs ago this Christmas. I was a -10 and need nothing now. I was slightly undercorrected in my non-dominant eye so when the time came when I would normally require reading glasses, the undercorrected eye would take over and I would not need the reading glasses. I do not even notice it except at night when driving. I have a pair of glasses specifically for driving at night. It just clarifies things a bit.
Any "enhancements" I may need in the future are included and no charge, as well as a yearly check-up and any glasses I may need. I truly feel I will not need any additional surgeries. I have actually gotten better over time, as the halos are less prevalent. My vision is 20/20 and 20/40.
I researched this procedure for over 3 yrs before I decided to get it done. I also researched the doctors and inquired as to how many of this procedure they had personally done. I went with the most experience. He had done over 17,000 vs the local doctor with less than 1,000.
It is SO NEAT to be able to open my eyes at night and see the clock, let alone read it. Staying out later than normal and not needing eye drops or contact cases and glasses. Not ordering contacts and buying solutions. No traveling hassles. Not having glasses fog up when you go outside from the change in temperature.
I understand the neuroses (sp) from a medical standpoint. I too am in the medical field. (microbiology). That's also why it took me so long to decide to have it done.
I hope some of this helps. Since you are in Canada, your ophthalmologists have been doing this procedure longer than the US drs. My doc came from Canada. That is why he had so much more experience than anyone else did. The US had only just appoved the procedure a year before I decided to do it. Canadians had the procedure for 7 yrs prior.
