LASIK is considered an elective and cosmetic surgery, meaning that it is not usually deemed medically necessary. . LASIK can improve your quality of life by potentially eliminating the need for glasses or contacts. LASIK (laser-assisted in situ keratomileusis) is the most commonly performed laser eye surgery to treat myopia (nearsightedness), hyperopia (farsightedness) and astigmatism. LASIK can improve vision and have a positive, lasting impact. Around 80 percent of people who get LASIK surgery will have no need for glasses or contacts after the procedure.
Like other types of laser refractive surgery, the LASIK procedure reshapes the front surface (cornea) of the eye to enable light entering the eye to focus on the retina without glasses or contact lenses. LASIK typically is pain-free and requires only about 15 minutes to treat both eyes. Vision improvement is immediate and often stabilizes in as little as 24 hours.
Nearsightedness: Myopia is a very common condition in which the light coming into the eye is not focused properly onto the retina, making it difficult to see objects far away. The condition is usually caused by an elongation of the eyeball that occurs over time.
Farsightedness: Hyperopia is the opposite of myopia, and is usually caused by shortening of the eyeball.
Astigmatism: is an imperfection of the cornea preventing part of it from focusing light onto the retina. The result is a blurred area within an otherwise clear image. This problem may occur along with either myopia or hyperopia. These frequent conditions are termed “refractive errors.”
There are three essential steps to a LASIK procedure:
