Astigmatism is a refractive error that can be corrected through LASIK surgery. It is a relatively common eye problem and it can occur among children and adults alike. Astigmatism is similar to nearsightedness and farsightedness.
What is Astigmatism?
Astigmatism occurs when the cornea is improperly shaped, making it difficult to focus light onto the retina. The light rays that enter the eye do not focus evenly on the retina, which results in a blurred image. Objects that are near or far away will still be blurry for a person with astigmatism.
Symptoms of Astigmatism
Blurred vision, eye fatigue, eye strain, and headaches are all associated with astigmatism. Astigmatism may make some more sensitive to light, as well as make driving at night difficult. All of these symptoms can be treated through vision correction.
Treatment for Astigmatism
Sometimes astigmatism can range from mild, which would require no treatment, to severe, which may require LASIK surgery. Here are some options to treat astigmatism.
● Corrective lenses – Corrective lenses bend the incoming light rays to compensate for refractive errors, so that the images received will be properly received by the retina. Corrective lenses come in the form of eyeglasses or contact lenses.
Contact lenses come in three types: rigid, gas permeable and soft contact lenses. Rigid contact lenses are made of a combination of plastic and glass. Gas permeable contact lenses use polymers, which is a type of plastic. Soft contact lenses are made out of hydrogel, a combination of water and polymer.
● Astigmatic Keratotomy – This is a refractive surgical procedure that can correct astigmatism. Incisions are made on the steepest parts of the cornea which causes it to assume a more spherical shape. The light would then precisely focus on the retina so the vision would become clearer and sharper. Astigmatic keratotomy takes only a few minutes to perform and can be performed in conjunction with other refractive procedures.
● LASIK – LASIK is widely considered one of the safest and most effective ways to treat refractive errors. It is painless and has a much faster recovery period than keratotomy. LASIK is the most preferred refractive surgery, by doctors and patients alike.
