How does LASIK work and are there needles involved?
Vision is corrected by reshaping the inner corneal bed of the eye. This is done by removing a very thin layer of tissue from the front surface of the eye called the cornea – placing the lens power of your glasses on the cornea. Persons being treated remain remarkably comfortable though the entire procedure, requiring only a few anesthetic drops in the eye to ensure a virtually pain-free procedure that takes only minutes. No needles are used and with current technology there is very little discomfort after the procedure. A more detailed explanation (complete with pictures).
