Laser surgery is very normal and common refractive surgery used to treat myopia, hyperopia and astigmatism. However there are several kinds of laser surgeries nowadays, different surgery requires different recovery period. PRK surgery is the original laser surgery. During PRK surgery, the surgeon will remove the whole epithelial layer of cornea, which makes its recovery period rather longer than other type of laser surgeries. Because there is no blood vessels on cornea but just millions of nerve ends, so it heals very slow and it is easier to get infection and haziness because of the wound, but it reduces the risk of complication. It takes circa 6 months to healed up averagely. While the lasik surgery, which is more popular and common today, requires a much shorter recovery period, because in Lasik surgery, the surgeon won’t wipe off the outer layer of cornea but create a flap to access the treatment area. However because of the created flap, it increases risk of infection and complication. Usually one week after a Lasik surgery, the patient can restore most vision.
