It is estimated that well over 60 million Americans wear glasses or contact lenses. The vast majority of these people have common vision problems that can be easily remedied by LASIK. Read on to learn more about these conditions and how your eyes work.

LASIK: Your Cornea and Your Retina

The eye is a very complex part of the human anatomy, but you don’t need to be a scientist to understand the most basic vision problems. All you really need to know about is the function of the cornea and the retina. All light passes through the cornea when it enters the eye. It refracts this light to the retina which is the light-sensing part of the eye. When there are irregularities in the cornea, they interrupt the way light gets to the retina and vision problems occur. LASIK corrects these corneal imperfections to improve your vision.

Astigmatism is the most common vision problem. It is an irregular curvature or shape of the cornea (kind of like a football) that causes both distance and near objects to be blurred. It causes light rays to focus on two points in the back of your eye, rather than on just one. LASIK helps many people overcome astigmatism.
LASIK: Irregularly-Shaped Cornea LASIK: Myopia or Nearsightedness

Myopia or nearsightedness means that you can see near objects but not far objects. It is a vision problem experienced by approximately one-third of the population. Myopia occurs when the eyeball is slightly longer than usual from front to back. This causes light rays to focus at a point in front of the retina, rather than directly on its surface. LASIK helps many people overcome myopia.
LASIK: Nearsightedness and Focal Point Diagram LASIK: Hyperopia Farsightedness

Hyperopia or farsightedness means that you can see objects in the distance but have trouble with objects up close. It is a common vision problem affecting a significant portion of the population. This problem occurs when light rays entering the eye focus behind the retina, rather than directly on it. LASIK helps many people overcome hyperopia.

If you wear reading glasses before LASIK you will likely need reading glasses after.
