To able to see clearly, the cornea and the lens must bend or refract the light rays to focus on the retina which is a layer of light-sensing cells that line the back of the eye. If the light rays don’t focus on the retina, you begin to see everything blurry. This is called a refractive error. Basic types of refractive errors are nearsightedness (myopia), farsightedness (hyperopia), astigmatism or presbyopia. The aim of glasses, contact lenses, and refractive surgeries is to eliminate these errors by making light rays focus on the retina.

Laser eye surgery is a surgical vision correcting procedure in which eye’s cornea is reshaped, and poor vision is corrected by using an extremely precise excimer laser. These surgeries may successfully and safely bring back 20/20 vision, reduce and even eliminate the need for glasses or contact lenses. 

LASIK Eye Surgery is the new trend as far as vision correction technology goes, so let's read up on some interesting facts.

A LASIK procedure is a relatively new laser eye surgery or laser vision correction technique used to treat myopia, hyperopia and astigmatism. This procedure has gained a lot of popularity in recent years due to the high patient satisfaction rates, which are usually between 92% and 98%.
