It is the kind of freedom that allows people to make lifestyle choices that were not options to them before because they were totally dependent on glasses or contact lenses. These advantages have resulted in the growing popularity of this operation among refractive surgeons all over the world. This flap allows for rapid recovery of vision and reduces discomfort after the procedure. The second technique uses an FDA-approved excimer laser to sculpt the underlying cornea, correcting the refractive error. The eye is not patched, but a protective shield is placed over the eye to prevent inadvertent rubbing of the eye.
Visual recovery is typically rapid, and there is little or no post-operative pain.
Eye drops, including an antibiotic to guard against infection, are taken for a week. After topical anesthetic eye drops are placed in the eye to minimize sensation, the eyelids are secured in the open position using a lid speculum. The eye is then stabilized with a suction ring which fits snugly on the eye. This allows the cornea to protrude through the hole in preparation for the microkeratome. You will not feel pain during this stage, however, vision will darken during the time the suction is applied and there may be a slight pressure sensation.
