What is Lasik and How Does it Work?
If you're tired of wearing glasses or contacts and want to get rid of them for good, LASIK eye surgery may be right for you.
Here's how it works: LASIK is a type of laser refractive surgery that can correct vision problems like nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. During LASIK surgery, a special type of cutting laser is used to precisely change the shape of the dome-shaped clear tissue at the front of your eye (cornea) to improve vision.
In eyes with normal vision, the cornea bends (refracts) light precisely onto the retina at the back of the eye. But with nearsightedness (myopia), farsightedness (hyperopia) or astigmatism, the light is bent incorrectly, resulting in blurred vision. Glasses or contact lenses can correct vision, but reshaping the cornea itself will provide the necessary refraction.
Are there side-effects?
You should understand that there are risks involved with any surgical procedure. Eye surgeons have performed millions of successful procedures worldwide since its introduction in 1995, however some patients experience temporary side effects such as halos around lights at night or glare from bright sunlight during recovery time after surgery.
