LASIK is a form of laser-guided surgery to the eye meant to improve or correct issues with sight. The surgical procedure is performed by ophthalmologists, who are mDs specializing in eye disorders & diseases. LASIK is ordinarily a preferred alternative to pRK surgery, as it is much less painful and requires less time to recover completely. Prior to LASIK surgery, the patient's corneas are examined with a computer controlled sophisticated scanner and a map of the cornea is created. This step of the procedure also picks up astigmatism & other deviations in the cornea's shape. The eye surgeon uses this data to ascertain the amount as well as location of corneal tissue to be eliminated during the operation. The operation is performed with the person awake and alert, nevertheless, the patient is generally given a mild sedative and anesthetic eye drops. The operating surgeon operates the laser machines, which do all of the cutting. A flap is carved in the cornea, which is the clear front part of the eye, using a laser or a blade. Then an excimer laser is used to remodel the cornea. The laser destroys tissue without causing harm to the eye. Although usually uncommon, some complications could occur with LASIK or any eye surgeries. Some of the more typically reported complications of LASIK typically include: infection, light sensitive or dry eyes, under or over correction, changing vision, starbursts or halos around lights, double vision, and issues with the flap that was produced during the operation. Although LASIK technology is improving very rapidly, research studies have not proven long-term or permanent complications. The eye surgery can't be reversed.
