Astigmatism is a visual impairment that is caused by an irregular curvature of the cornea or the lens behind it. You know that you see objects through the reflection of light on an object. The light reflected by an object travels to the retina through the cornea and the lens. In a normal spherical curvature of the cornea, light is bent or refracted evenly so that the light hits a single point in your retina. When you have astigmatism, the light rays are refracted unevenly so the resulting image is out of focus. Treating astigmatism, therefore, necessitates correction of the abnormal curvature of the cornea or the lens, whichever of the two is causing the problem.

Lasik astigmatism procedure or laser in-situ keratomileusis is just one of the surgical means of correcting astigmatism. Other surgical procedures apart from lasik astigmatism procedure include astigmatic keratotomy and excimer laser photoastigmatic refractive keratectomy. There are also variations to lasik astigmatism procedure.

The main object of all these surgical procedures is to correct the irregular curvature that is causing improperly refracted and thus incorrectly focused images. And to do this, there is a need to flatten extra tissue that’s causing the irregularity. But unlike other procedures, lasik astigmatism surgery does not require perforating incisions of the cornea. The lasik astigmatism procedure also does the correction using a computer-guided laser and through a protective layer of corneal tissue. The result is a much safer astigmatism treatment procedure.

Laser technology such as lasik astigmatism treatment is also useful for nearsighted and farsighted people. After all, the reshaping of the cornea is required in both instances. However, lasik technology is more useful in astigmatism treatment because more precision is required in correcting an unevenly curved cornea.
