Understanding LASIK Eye Surgery

LASIK stands for Laser-Assisted In Situ Keratomileusis. It is a surgery lasik procedure that aims to correct refractive errors in the eyes, such as nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. The goal of LASIK is to reshape the cornea, the clear front surface of the eye, so that light properly focuses on the retina, resulting in clear vision.

LASIK utilizes advanced laser technology to precisely remove tiny portions of corneal tissue. By reshaping the cornea, LASIK corrects the imperfections that cause vision problems.

The Science Behind LASIK

To understand how LASIK works, it is important to have a basic understanding of the anatomy of the eye. The cornea, which is responsible for about two-thirds of the eye’s focusing power, plays a crucial role in vision. When the cornea is misshapen, it can cause light to focus in front of or behind the retina, resulting in blurry vision.
