I'm looking at having eye surgery to correct my vision, as I'm tiring of wearing glasses; in particular with a deployment on the horizon. I am less skeptical about laser surgery now but still have my concerns. I have heard of Orthokeratology which consists of inserting shaped contact lenses into the eye at night, which gently compresses the cornea flat in line with your prescription needs. On removing them the wearer gets a day's worth of perfect vision without the hassle of a contact lens. Apparently the Chinese used to do this hundreds of years ago by sleeping with small bags of sand resting on their eyelids Seems ideal. Any one heard of this before?
