LASIK, or Laser-Assisted In Situ Keratomileusis, is a type of refractive surgery that has been widely used to correct vision problems such as nearsightedness, farsightedness, and astigmatism. This surgical procedure involves creating a thin flap in the cornea, which is then reshaped using an excimer laser to improve visual acuity.
The procedure begins by creating a thin flap in the cornea using a specialized instrument called a microkeratome or an IntraLase femtosecond laser. The surgeon then folds back the flap to access the underlying tissue, where the excimer laser reshapes the cornea to correct the vision problem.
While LASIK has been shown to be highly effective in correcting vision problems, it's essential to understand that like any surgical procedure, there are potential risks and complications. These may include dry eye syndrome, visual disturbances, and infection.
