LASIK is a type of laser eye operation meant to minimize or repair difficulties with eyesight. The surgical procedure is carried out by ophthalmologists, who are medical doctors who specialize in disorders of the eye. LASIK is ordinarily a preferred alternative to pRK surgery, as it is much less painful and requires less time to heal completely. Prior to having LASIK eye surgery, the patient's corneas are examined with a computerized sophisticated scanning device and a map of the cornea is made. This step of the procedure also spots astigmatism and also additional irregularities in the cornea's shape. The operating surgeon uses this information to compute the amount and location of corneal tissue to be eliminated during the operation. The surgery is carried out with the person awake, nevertheless, the patient is generally given a modest sedative and anesthetizing eye drops. The eye surgeon operates the lasers, which produce all of the cutting. A flap is sliced in the cornea using a laser or a blade. Subsequently, an excimer laser remodels the cornea. The laser destroys tissue without inducing damage or injury. Although relatively uncommon, some complications can occur with LASIK or any eye surgeries. Just a few of the more typically reported complications of LASIK can include: infection, dry eyes and light sensitive eyes, over or under correction, changing vision, rings around lights, doubled vision, and disorders with the flap that was created during the surgery. Although LASIK technology is getting better rapidly, scientists have not proven long-term complications or damage. The procedure can't be reversed.
