The main benefit of a flapless procedure (PRK) is that it is not susceptible to flap complications sometimes associated with severe eye trauma. Typically, such flap issues do not occur with mild to moderate eye trauma, i.e. the level of trauma associated with sporting injuries. However, there have been reported occurrences of flap problems for patients facing other severe eye injuries. The advancement of femtosecond laser (i.e. bladeless) LASIK flaps has significantly decreased the chances of a flap complication.
