LASIK (Laser-Assisted in Situ Keratomileusis) is a laser eye surgery used to correct and enhance the vision of long-sighted (hyperopic) and short-sighted (myopic) people, as well as those with astigmatism. It is a surgical procedure intended to reduce a person's dependency on glasses or contact lenses in the long term. A LASIK procedure uses a laser to alter the shape of the cornea, which allows light travelling through it to focus on the retina at the back of the eye, allowing the person to view images in focus. The surgery takes around 15 minutes under a local anaesthetic. There are some risks associated with LASIK eye surgery. Because it is a very technical surgery, problems can occur. The ideal candidate should be over 18, who has had stable vision and an optical prescription for at least the last two years. Those with only mild long-sightedness, short-sightedness or astigmatism may not be suitable candidates. LASIK eye surgery prices start from approximately £895 per eye. More advanced LASIK can cost £1295 per eye.
