What is Astigmatism?

Astigmatism is the shape of the cornea being shaped irregularly, similar to a football instead of a baseball. Most astigmatic corneas cause blurry vision which requires patients to wear glasses or contacts. The reason for the blurry vision is the astigmatism causes the light to be deflected to the wrong area of the retina when trying to see (as depicted in the image). Astigmatism can cause blurred visions at both a distance and up close. Astigmatism is most common in farsighted patients.

Treatment Options for Astigmatism

Astigmatism can be corrected with glasses and contacts to help refract the irregular shaped cornea to the correct focal part of the retina, using cylinder in your refractive prescription.

Astigmatism can also be treated surgically here at St. Michael’s Eye & Laser Institute, through Astigmatic Keratotomy, a procedure our Ophthalmologists perform which involves placing microscopic incision on the eye.


LASIK is another option for Astigmatism patients, St. Michael’s Eye & Laser has been using to help astigmatic patients since the founding of LASIK. Dr. John Michaelos, M.D. at St. Michael’s Eye & Laser has been pioneer in LASIK refractive surgery performing thousands of surgeries to help astigmatic patients, eliminating the need for glasses or contacts. This process involves reshaping the cornea using an all laser procedure which makes the cornea more uniform.
