Astigmatism is one form of refractive error that impairs vision. It is
a common eye condition affecting millions of people. Astigmatism is an
imperfection in the curvature of the cornea. The cornea and lens of the
eye should be smooth and evenly curved in all directions in order to properly
refract light, allowing clear vision. Astigmatism does not allow light
to properly focus on the retina, and produces a doubling or ghosting effect
in vision. Astigmatism affects both distance and close range vision.
If you are experiencing problems with your vision, it is important that
you understandastigmatism symptoms and your options forastigmatism treatment.
There are two types of astigmatism: corneal astigmatism and lenticular
astigmatism. Corneal astigmatism is an irregularly shaped cornea. Lenticular
astigmatism is an irregularly shaped lens of the eye.
Many people are born with astigmatism, and it may be accompanied by other
refractive errors such as nearsightedness or farsightedness. People who
are not born with astigmatism can develop it as a result of eye injury
or disease. While adults who have astigmatism may recognize their vision
isn’t as clear as it should be, children won’t necessarily
recognize there is a problem with their vision. Routine vision exams are
important in diagnosing any vision problems such as astigmatism in children
and adults so that it can be properly corrected.
Symptoms of astigmatism:
o Blurry vision
o Eye strain
o Squinting to see clearly
o Eye discomfort
Simply because you experience these symptoms doesn’t mean you have
astigmatism, as these symptoms may also be related to other refractive
vision errors, but only your doctor will be able to diagnose to cause
of distorted or blurred vision.
Treatment for astigmatism has improved over the years. In the past, individuals
with astigmatism were confined to rigid (or hard) contact lenses or eyeglasses
for vision correction. Today, many patients with astigmatism have the
option of toric lenses, which are soft contact lenses.
In most cases, LASIK eye surgery can treat astigmatism by reshaping the
cornea. Reshaping of the cornea will improve how the eye focuses light
rays on the retina. A consultation with your eye doctor is necessary to
determine the best treatment options for astigmatism.
