How does Lasik work?

LASIK stands for laser-assisted in-situ keratomileusis. LASIK surgery requires the use of an excimer laser to change the shape of the cornea. This change creates better vision for people who have numerous vision problems like nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. There are several types of laser vision correction surgeries that patients can choose from with the help of their LASIK surgeon. LASIK works by correting the curvature of the cornea to give people the chance to have 20/20 vision.

Types of Lasik procedures

• Blade-based LASIK

• LASEK (Laser-assisted epithelial keratomileusis)

Custom LASIK

Wavefront-guided LASIK

• IntraLASIK


During standard LASIK eye surgery, the physician numbs the eye and holds it open with a speculum. A “microkeratome” is then used to create a small flap in the top layer of the cornea. The cornea is then folded back and the excimer laser is used reshape the curvature of the tissue before the flap is replaced.

Benefits of laser vision correction procedures:

• Possible 20/20 vision

• Reduced or no need for eyeglasses and contact lenses

What types of vision problems does LASIK correct?
