LASIK for Astigmatism: Everything You Need to Know
March 9, 2017
Most people have some degree of astigmatism. However, very few really know anything about it, or that LASIK can permanently correct astigmatism. So, what exactly is astigmatism, and how can LASIK fix it?
To help you find these and other answers, here’s everything you need to know about LASIK for astigmatism.
What is Astigmatism?
Astigmatism is a refractive error caused by an irregularly shaped cornea. Normally, the rounded shape of the cornea bends the light in the eye to focus it clearly on one point of the retina. An irregularly shaped cornea causes the light to focus on two different points instead of one resulting in blurred vision.
Most people who have astigmatism are usually born with it. It can also develop after an eye injury or eye surgery. In some cases, astigmatism can be caused by keratoconus. Keratoconus is a rare condition that changes the shape of the cornea and causes it to become thinner.
The most common symptom of astigmatism is blurred vision. Many patients may also experience eye strain and headaches, especially after reading or using the computer for extended periods of time.
LASIK Eye Surgery for Astigmatism
Glasses and contact lenses can help you see clearly, but only temporarily. If you want to correct astigmatism permanently, LASIK eye surgery is the way to go.
LASIK eye surgery is a quick and easy procedure that permanently corrects refractive errors like astigmatism. First, the surgeon will create a flap to expose the cornea. Then, a laser is used to reshape the cornea to the appropriate curvature. Once that is complete, the flap is put back in place.
LASIK helps those with astigmatism achieve crystal-clear vision. However, before you can undergo the procedure, you must be evaluated to determine if you are a good candidate for LASIK.
Those who do qualify for LASIK typically have good eye health, are 18 years of age or older, and have had little to no change in vision within the past couple of years.
LASIK Eye Surgery Recovery
Most astigmatism patients will experience clearer vision as early as the morning after undergoing LASIK eye surgery. But you will want to take a few precautions during the LASIK eye surgery recovery period to make sure your eyes heal properly.
For example, you should limit your time on the computer and in front of the TV after LASIK to prevent eye strain. You should also wait a few weeks before you start exercising again to reduce the risk of eye injuries.
Most importantly, you must schedule regular follow-up appointments with your eye doctor for the first few months after LASIK. During these appointments, your doctor will check your eyes and vision for any issues.
LASIK eye surgery is an ideal vision correction solution if you want to see clearly for years to come. To learn more about how LASIK can fix astigmatism, schedule your free LASIK consultation at Kremer Eye Center now.
