LASIK - short for "laser in-situ keratomileusis"

LASIK has become the standard of care in refractive surgery and is used to correct nearsightedness, farsightedness and astigmatism. In this procedure, the surgeon creates a hinged corneal flap before the excimer laser is applied to vaporize a small amount of corneal surface. After the laser is used, the corneal flap is replaced, bonding almost instantly and without stitches. Because the surface of the eye is not disturbed, there is little post-operative discomfort, few complications and a quick recovery time.



There are three common types of Refractive Errors:

Myopia - (nearsightedness) is a refractive error that causes poor distance vision. Either the eye being too long can cause myopia or your cornea having too much focusing power, as a result the image focuses in front of the retina.

Hyperopia - (farsightedness) is the opposite of Myopia. The distant images are seen as clear but the objects up close appear blurry. An eye that is too short or a cornea that lacks the necessary refractive power to focus images on the retina causes this.

Astigmatism - is a condition that blurs and distorts near and far objects. A normal cornea is round with even curves. If you have astigmatism, your cornea is shaped more like the back of a spoon, curves more in spots and not in others. Light rays have more than one focal point and focus on different areas of the retina.
