Before surgery, doctors will evaluate you and determine if you're a candidate for refractive surgery. Types of refractive surgery for astigmatism include: Laser-assisted in-situ keratomileusis (LASIK). With this procedure, an eye surgeon makes a thin, hinged flap in the cornea.
While glasses, contact lenses and orthokeratology (Ortho-k) can temporarily treat the effects of astigmatism, surgery is the only way to permanently correct it. Laser eye surgery and, in some cases, implantable toric lenses, can be used for permanent astigmatism correction.
Astigmatism surgery offers a range of corrective procedures that can improve your vision and enhance your quality of life. In this article, we will discuss the different surgical options available for astigmatism correction.
Refractive surgery. With LASIK and other procedures , a laser reshapes the cornea to adjust how light travels through it. There is no best way to correct your astigmatism—the most appropriate correction is one that best suits your vision needs and lifestyle.
The LASIK procedure for astigmatism involves reshaping your cornea. A misshapen bend of the cornea causes astigmatism. Eyes without astigmatism have an evenly rounded surface like a...
LASIK (laser-assisted in situ keratomileusis) is an FDA-approved laser eye surgery that corrects refractive errors like nearsightedness, farsightedness, and presbyopia. It can also treat mild to moderate astigmatism by reshaping the cornea.

Vision correction surgery (including LASIK eye surgery and photorefractive keratectomy or PRK eye surgery) uses lasers to fix vision problems. A specially trained ophthalmologist will perform these procedures to change the shape of your cornea so light hits your retina correctly.
It’s usually treatable with eyeglasses, contact lenses, or refractive surgery. What is Astigmatism? Astigmatism is a common and treatable eye condition that occurs when either the cornea or the lens has an irregular shape. It’s a type of refractive error that causes blurred vision at all distances.
LASIK corrects refractive errors, such as nearsightedness (seeing things better up close) or farsightedness (seeing things better in the distance), and astigmatism (an out-of-the-ordinary shaped cornea or lens). With these errors, light doesn't fall correctly on the light-sensitive retina at the back of the eye.
