LASIK is a form of laser-guided eye operation which is intended to repair disorders with sight. It is carried out by ophthalmologists, who are mDs who specialize in eye disorders & diseases. LASIK is generally a preferred alternative to photorefractive keratectomy, or PRK, as it is less pain-producing and requires less time for full recovery. Prior to having LASIK eye surgery, the patient's corneas are examined with a computerized scanning device and a corneal map is created. This procedure also detects astigmatism & other deviations in the shape of the cornea. The eye surgeon uses this information to judge the location as well as the amount of corneal material to be eliminated during the surgery. The surgery is done with the person awake and alert, even so, the person is generally given a mild sedating drug and anesthetizing drops in the eyes. The operating surgeon operates the laser machines, which do all of the incisions. A flap is cut in the cornea using a blade or laser. Afterwards, an excimer laser is used to remodel the cornea. The laser destroys tissue without causing damage to the eye. Although relatively uncommon, damaging complications do occur with LASIK or any eye surgeries. Some of the more commonly reported complications of LASIK are: infection, dry or light sensitive eyes, over or under correction, fluctuating vision, halos or starbursts around lights, double vision, and issues with the flap that was created during the operation. Although LASIK technology is getting better quickly, studies have not proven long-term or permanent damage. The eye surgery is irreversible.
