I thought about I long and hard before deciding to do it. When my optician said I was damaging my eyes by wearing my soft contact lenses for too many hours a day, starving me eys of oxygen, I decided it was healthier for my eyes.
The cornea is amazing tissue, it heals really fast. It reattaches itself within a minute of the LASIK treatment. There are risks and you have to weigh them up before doing, but if you get a reputable surgeon the risks reduce. Mine was very professional, I had my prescription measured by two different opticians at the clinic prior to the surgery to make sure the mesurements were correct, and they were double checked as it was fed into the computer. It was all over so fast, and immediately afterwards I had 2/20 vision. Awesome. Bit scratchy for the first day, but no worse than what your eyes feel like after a days skiing in bright sunlight with contact lenses.
There ar two types of laser surgery, I had what they call LASIK here, they cut a flap on the cornea, shape the underlying cornea with the laser and then let the flap backdown. The other method is PRK, they burn the outer surface of the cornea, this is the original laser treatment that has been superceded by the LASIK. It takes longer to recover and you don't get 20/20 eyesight immeidately. They only use this treatment for people who are suitable for LASIK, luckily I was, I don't think I would have PRK.
The clinic I went to said only 50% of people are suitable. Lots of factors are take into account, including how thick your cornea is. My cornea was 500 microns thick (half a millimetre), they only had to remove 30 microns to correct my vision, my prescription was 2.0. This is a minute amount.
I waited until the end of the ski season (September down under), stopped wearing my contacts for 3 months and then got surgey in November. My surgeon said not to wear your contacts for 3 weeks prior to the surgery so your cornea returns to its natural shape. Considering the minute amount they take off, I wanted to make sure it was totally back to its natural shape so there was no risk of it changing further after surgery, so wore my glasses for 3 months - yuk!
My eye prescription has not changed for 8 years. Stability of your prescription is antoher factor. They are effectively shaping the cornea to meet your current prescription. If you keep having to get stronger glasses every couple of years then maybe in a couple of years time you might need further correction.
It's important to keep your eyes well lubricated afterwards. After 5 months I still put drops in when I wake up because they quite dry. Much less hassle that putting contacts in and out.
I'm a convert! In New Zealand it costs $2000 NZD per eye, asn NZD is worth about 41c USD.
