text: If you are under 18, or your prescription is constantly changing, then it's not worth getting  until your eyes are stable. I wouldn't really recommend it for older people(over 70)for slower healing . Also, there are an awful lot of health problems that can prevent you from getting it done such as type 1 diabetes, clinical dry eye, pregnancy & rheumatoid arthritis to name a few.Your eye has to be thoroughly checked to ensure that it is able to take the treatment as well.The other one is expectation. You aint gonna be able to see through walls and stuff, but it's certainly a life changing surgery. The majority of people are suitable for it and don't be put off by stupid stories.You can have cateract surgery after you've had it done and unless your optometrist is incompetent, you shouldn't get a detatched retina, as the eye screen to check suitability should pick up any risk, including that.\nTry http://www.opticalexpress.co.uk\nOr http://www.visx.com\nThey have the Visx Laser, and Visx actually invented laser eye surgery and hold all the patents, so are the market leaders. Everyone else chases their tails.
