LASIK is a type of laser-guided eye operation meant to correct or at least minimize issues with eyesight. The operation is carried out by ophthalmologists, who are medical doctors specializing in diseases and disorders of the eye. LASIK is usually preferable to pRK eye surgery, as it is less painful and requires less time for fulll healing. Before having LASIK surgery, the patient's corneas are analyzed with a computerized sophisticated scanner and a map of the cornea is made. This process also discovers astigmatism as well as additional problems in the cornea's shape. The eye surgeon uses this data to judge the amount as well as location of corneal tissue to be eliminated during the operation. The surgery is performed with the person awake, however, the person is typically given a mild sedating drug and anesthetizing drops for the eyes. The surgeon operates the laser machines, which create all of the cutting. A flap is cut in the cornea using a laser or a blade. Afterwards, an excimer laser remodels the cornea. The laser vaporizes tissue without creating damage to the eye. Although usually uncommon, damaging complications may occur with LASIK or any type of eye surgeries. A number of the more commonly reported complications of LASIK can include: infection, dry or light sensitive eyes, under or over correction, fluctuating vision, rings around lights, doubled vision, and disorders with the flap that was produced during the surgery. Although LASIK technology is getting better quickly, research studies have not completely defined long-term complications or damage. The lASIK procedure is irreversible.
