When Does Astigmatism Call for LASIK?

Book Appointment

LASIK is an innovative, minimally invasive surgery that can quickly reshape your cornea to improve your vision.

As a skilled optometrist, Tanya Lau, OD, offers on-site LASIK consultations to determine if you’re a good candidate for this type of laser procedure. Dr. Lau bases her decision on your overall health and your existing vision issues.

One of the main reasons people seek LASIK treatments is to correct a common vision issue known as astigmatism.

How astigmatism affects your vision

Astigmatism is a condition that develops when there’s an issue with the curvature of your eye. This curvature causes your vision to appear blurry and distorted at both a distance and close up.

To correct astigmatism and clear your vision, you must rely on eyeglasses or contact lenses for your day-to-day activities. Now, with advancements in laser technology, you can also correct your eye curvature with a laser-assisted in-situ keratomileusis (LASIK) procedure.

LASIK for treating astigmatism

LASIK treatment can clear your vision with little risk and minimal downtime. Your provider performs the procedure on an outpatient basis and provides medications to keep you relaxed and comfortable.

The laser technology creates a flap in your cornea to correct the curvature of your eye and clear your vision. Within 24 hours of your procedure, you can begin seeing more clearly, and you’ll continue to see improvement in the days that follow.

Overall, treatment takes only a few minutes for each eye and you only need a brief period of recovery before you can go home. Dr. Lau offers post-LASIK evaluations to ensure your eyes are healing properly and your vision is improving. She can also provide guidance as to when you can return to work and other activities without harming your eye health.

The best candidates for LASIK

The goal of LASIK for treating astigmatism is to correct the curvature of your eye so that you can see clearly without contacts or glasses. However, it’s important that you have realistic expectations for your procedure.

Dr. Lau can discuss how LASIK may benefit your vision based on your individual medical history, overall eye health, and the severity of your astigmatism. In most cases, LASIK is best-suited for those who have mild curvatures and can provide vision improvement significant enough to eliminate the need for glasses and contacts.

If you have moderate-to-severe astigmatism, you may not achieve the same results with LASIK. In some cases, you may have better vision, but still will need to rely on glasses or contacts for some activities, like driving or reading. Even when LASIK is initially successful at clearing your vision, you may eventually need prescription lenses as you get older.

Why you may not qualify for LASIK

Since severe astigmatism may not be addressed completely with LASIK, Dr. Lau can determine if you should move forward with the laser therapy after a vision assessment.

You may also not qualify for LASIK if you have:

  • An infection
  • Large pupils
  • Dry eye syndrome

Existing eye diseases, like glaucoma or diabetic retinopathy, may also exclude you from receiving a LASIK treatment.

Your general health is also a consideration before a recommendation for LASIK and chronic health conditions, like diabetes or immune system disorders, may make a LASIK procedure risky.
