LASIK is a type of laser-guided eye surgery which is intended to rectify issues with eyesight. LASIK is carried out by ophthalmologists, who are mDs specializing in disorders of the eye. LASIK is typically preferable to pRK (photorefractive keratectomy), as it is much less painful and requires less time for fulll healing. Prior to LASIK eye surgery, the patient's corneas are analyzed with a computer controlled scanning device and it makes a map of the cornea. This step of the process also picks up astigmatism & other problems in the cornea's shape. The eye surgeon uses this information to determine the location as well as the amount of corneal tissue to be removed during the surgery. The operation is performed with the patient awake and alert, nonetheless, the person is often given a minor sedating medication and anesthetizing drops in the eyes. The operating surgeon operates the laser machines, which produce all of the incisions. A flap is cut in the cornea, which is the clear front part of the eye, using a blade or a laser. Then an excimer laser remodels the cornea. The laser vaporizes tissue without creating harm to the eye. Although usually uncommon, complications or damage could occur with LASIK or any type of eye surgeries. Just some of the more typically reported complications of LASIK can include: infection, dry eyes and light sensitive eyes, over or under correction, fluctuations in vision, halos or starbursts around lights, double vision, and problems with the flap created during the operation. Although LASIK technology is improving very rapidly, clinical studies have not proven long-term complications or damage. The surgery can't be reversed.
