Can LASIK Fix Astigmatism?

LASIK for astigmatism

LASIK, laser-assisted in-situ keratomileusis, corrects nearsightedness by flattening the cornea with a laser and treats farsightedness by steepening the cornea.  Astigmatism is a different visual problem. Instead of a normal round cornea you have one that’s more oval like a football, and the curvature causes your blurry vision. LASIK treatment for astigmatism doesn’t flatten or steepen the cornea; it corrects the uneven curvature of your cornea.

 

LASIK vs. Contact Lenses for Astigmatism

LASIK for astigmatism is an excellent option when compared to other alternatives like eyeglasses or contact lenses. Eyeglasses and contacts compensate for the abnormal curvature of the astigmatism with a lens that is curved in the opposite way from the cornea, effectively cancelling out the distortion. Unlike LASIK, these are short-term corrections to the symptoms associated with astigmatism- blurry vision, eyestrain, and headaches. They can also be disorienting since, by definition, these lenses are non-uniform in shape.  Astigmatism contacts can also rotate out of alignment causing blur.  And all contact lenses carry the risk of infection, inflammation, or corneal damage.

PRK and LASEK for Astigmatism

With reshaping the surface of your eyes, temporary fixes like contact lenses or glasses become unnecessary in many cases. There are different types of refractive surgeries. PRK, or photorefractive keratectomy, involves your surgeon removing the outer, protective layer of your cornea before changing its curvature. LASEK, or laser-assisted subepithelial keratomileusis, different from LASIK, involves the folding of an extremely thin layer of the cornea, unlike the slightly thicker flap seen in LASIK.

LASIK for Astigmatism

LASIK for astigmatism involves your surgeon making a thin, small circular hinged cut into your cornea. He or she folds back the hinged flap and then reshapes the cornea using an excimer laser that doesn’t produce any heat. Many people choose to have LASIK for astigmatism over other refractive surgeries because it is very safe and the recovery time is very short.

Since the U.S. Federal Department of Agriculture (FDA) approved LASIK in 1998, its popularity and acceptance as a safe and minimally invasive surgery has grown. In fact, each year thousands of Americans, whether they have LASIK for astigmatism, nearsightedness or farsightedness, have undergone this surgery with great results. The vast majority of LASIK patients achieve perfect or near perfect vision without the use of temporary fixes like eyeglasses or contact lens.  Some LASIK patients may still need to make use of glasses for reading or driving, but LASIK can still provide life altering vision correction.

Before you choose to have LASIK a proper evaluation of the benefits, risks, and anticipated results, along with a consultation and evaluation with a physician, should be completed by each potential LASIK candidate. Numerous factors play into the eligibility of LASIK candidates and every person considering LASIK should make sure that they are able to comply with the post-surgical orders.  For instance, after surgery you shouldn’t rub your eyes. This can wrinkle or displace the thin corneal flap. Also, there may be side effects that tend to fade over time as your cornea heals, such as haziness and difficulty with night vision.
