LASIK Eye Surgery for Astigmatism
- Posted on: May 25 2012
Astigmatism is an eye condition in which the shape of the eye is abnormally curved.
The cornea and lens of the eye should be smooth and evenly curved in all
directions. An equally curved eye will properly refract light, allowing
clear vision. Astigmatism is an irregular shape of the cornea or lens.
Astigmatism means light does not hit the eye in such a way that it is
properly focused on the retina and both distance and close range vision
is affected. There are several treatment options for astigmatism, includingLASIK eye surgery and
People who are nearsighted or farsighted may still have astigmatism. Symptoms
of astigmatism include blurry vision, eyestrain, headaches and squinting
to see clearly, though these symptoms could also be caused by other refractive
errors. Astigmatism is a condition that occurs early in life, and can
be detected in a
comprehensive eye exam.
Mild to moderate astigmatism is most commonly treated with eyeglasses or
contact lenses. Astigmatism patients are no longer limited to rigid contact
lenses or eyeglasses. Toric lenses, which are soft contact lenses can
be used to correct vision in some instances of astigmatism.
There are several surgical options our eye surgeon may use to treat astigmatism, such as
LASIK eye surgery, PRK, astigmatic keratotomy and limbal relaxing incisions. LASIK surgery
to correct astigmatism involves a reshaping of the cornea to improve how
the eye focuses light rays on the retina.
Astigmatism patients who also have cataracts and are planning to have cataract
surgery have an additional option — an implantable lens that makes it
possible to treat the cataract and correct the corneal astigmatism at
the same time. This implantable lens is the new AcrySof® IQ Toric
lens, which takes the most trusted platform for precise astigmatism correction
and adds the enhanced image quality of an aspheric lens,
taking the Toric IOL to a whole new level. The unique design of the AcrySof® Toric IOL makes it possible to reduce
or eliminate corneal astigmatism and significantly improve uncorrected
