LASIK is a form of laser-guided eye surgery intended to repair disorders with vision. The surgery is performed by ophthalmologists, who are mDs who specialize in eye disorders. LASIK is ordinarily a preferred alternative to pRK surgery, as it is less pain-producing and requires less time for fulll healing. Prior to LASIK surgery, the patient's corneas are analyzed with a computer controlled sophisticated scanning device and it creates a map of the cornea. This step of the process also picks up astigmatism and also additional irregularities in the shape of the cornea. The surgeon uses this data to compute the location and amount of corneal tissue to be eliminated during the operation. The surgery is performed while the person is awake, nevertheless, the patient is typically given a mild sedating agent and anesthetic eye drops. The surgeon operates the laser machines, which produce all of the incisions. A flap is sliced in the cornea using a blade or a laser. Then an excimer laser remodels the cornea. The laser destroys tissue without inducing injury to the eye. Although relatively uncommon, complicating problems could occur with LASIK or any eye surgeries. Some of the more typically reported complications of LASIK include: infection, dry eyes and light sensitive eyes, under or over correction, changing vision, starbursts or halos around lights, double vision, and issues with the flap created during the surgery. Although LASIK technology is getting better rapidly, clinical studies have not ascertained long-term or permanent complications. The process can't be reversed.
