Involves simply removing and polishing the surface layer of the eye(cornea). This reshapes the eye and corrects most refractive errors.benefits:Simple technique with very little surgical risk.
no longterm flap risk - a consideration for certain situations (such as marial arts, construction, law enforcement, and dry sydrome). Surgery is on the top, superficlal layer of the cornea, making it generally safer.things to consider:Slower recovery than lasik - most people take on week off work : full vision recovery can take weeks/months for some.
potentially more discomfort in first few days. faint scarring may occur with strong treatments or re - treatments Small risk of recurrent corneal erosion syndrome(i.e awakening with irritation in the eye - may happen months after surgey).
