What Is LASIK?
LASIK, short for Laser in Situ Keratomileusis, is an eye surgery used to correct refractive errors. These errors refer to vision problems like myopia (near-sightedness), hyperopia (far-sightedness), and astigmatism (blurred vision). Made possible in the 1980s, the treatment is most common among refractive surgeries. Ophthalmologists use a special laser called an ‘excimer’ to reshape the cornea so that light travelling through it is properly focused onto the retina at the back of the eye. This procedure can be undertaken by people who are above 18 years of age and leads to reduced dependence on eyeglasses and contact lenses. According to webmd.com, 96% patients have desired vision after a LASIK treatment. However, it may lead to fluctuating vision. In 2009, 28 million patients in the US underwent LASIK procedure.
