How does PRK work and are there needles involved?
Vision is corrected by reshaping 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.
