Astigmatism

Astigmatism

Many patients with myopia and hyperopia have some degree of astigmatism, or an oval shape, to their cornea. It occurs when your cornea is shaped more like a football than a basketball. As a result, you experience distortion or tilting of images due to the unequal bending of light rays entering your eyes. People with high degrees of astigmatism have blurred vision for both near and distant objects.

The table below shows the categories of severity for astigmatism:

Mild Astigmatism < 1.00 diopters
Moderate Astigmatism 1.00 to 2.00 diopters
Severe Astigmatism 2.00 to 3.00 diopters
Extreme Astigmatism > 3.00 diopters

Every patient and prescription at TLC is looked at individually to decide what is best for them. TLC doctors are very prudent and thorough in deciding whether you are a good candidate for laser vision correction and will be happy to discuss the potential outcome and risks involved for a patient with your particular prescription.
