Because of the excimer laser, this procedure has a high degree of predictability. In the first part of the procedure, a thin flap of corneal tissue is created and moved over as though on a hinge. Next, the computer driven excimer laser is used to reshape the underlying tissue. Finally, the surface layer is repositioned. Vision usually recovers quickly and there is generally minimal discomfort following the procedure.
Most patients return to a normal lifestyle within a day.
This animation depicts the creation of the corneal flap, excimer laser corneal reshaping, and repositioning of the corneal flap.
