Astigmatism Detroit, What the heck is it anyway?

Astigmatism seems very mysterious, and many patients think that it is a rare disease, difficult to treat, and leading to poor vision. In fact, astigmatism is not much more difficult to deal with than the other refractive errors. Patients who have astigmatism have an unusual shape to the cornea. It is shaped more like a football instead of round like a basketball. This creates 2 points of focus inside the eye.

Astigmatism is just one of the 3 refractive errors of the eye. The other 2 are myopia (nearsightedness) and hyperopia (farsightedness).

There are specialty lens implants that can be placed at the time of surgery to correct this, just like glasses or contact lenses can. The lens makes the 2 points of focus into one, giving clearer distance vision. More info about refractive error is found on my website: 2020vision.com
