Can Laser Eye Surgery Correct Astigmatism?.. And Is It Right for You?

Can Laser Eye Surgery Correct Astigmatism?.. And Is It Right for You?

Astigmatism is a common refractive error that causes blurred vision due to an irregularly shaped cornea or lens.

If you have astigmatism and you’re looking for a more permanent solution to blurry vision, you may be wondering:

  • “Can I have Laser Eye Surgery for astigmatism?
  • “Can Laser Eye Surgery treat severe astigmatism?”
  • “What sort of treatment outcomes can I expect following the procedure?”

In this article, we’ll discuss:

  • What exactly is astigmatism (and its various sources and forms)
  • How Laser Eye Surgery is used to correct astigmatism
  • The latest and most effective treatment options

Here’s everything you need to know.

 

What is astigmatism?

Astigmatism is a condition where the eye’s cornea or lens has an irregular shape, causing light to focus on multiple points in the eye rather than a single point. This results in blurred or distorted vision at all distances.

It’s one of the most common diagnoses and is very manageable:

14%

of under-15s
have astigmatism

30%

of all people
have astigmatism

67%

of over-65s
have astigmatism

*Based on a study of 2124 patients.

There are two main types:

  1. Corneal astigmatism: Distortion of the cornea (outer part of the eye).
  2. Lenticular astigmatism: Distortion in the lens (inside the front of the eye).

Astigmatism can also be classified based on its relationship with other refractive errors:

  1. Myopic astigmatism (nearsightedness)
  2. Hyperopic astigmatism (farsightedness).
  3. Mixed astigmatism (both near and farsightedness).

 

Common symptoms of astigmatism

Although the brain accommodates for small distortions, significant astigmatism can cause:

  • Blurred vision (up close and/or far away)
  • Difficulty with night vision
  • Eyestrain or irritation
  • Frequent headaches
  • Squinting

This is why regular screening and vision testing by an eyecare specialist is vital — so that they can quickly identify, treat and prevent problems from worsening.

 

What does an astigmatic prescription look like?

An astigmatism prescription typically includes three components:

  1. Sphere (SPH): Indicates the lens power needed to correct nearsightedness or farsightedness
  2. Cylinder (CYL): Denotes the amount of astigmatism
  3. Axis: Specifies the direction of the astigmatism (measured in degrees)

It looks like this:

Laser Eye Surgery for Astigmatism

LASIK eye surgery for astigmatism has a very high success rate at AccuVision. It is an excellent procedure for most patients with astigmatism, and can be used to correct most types of astigmatism very effectively.

In fact, Mendoza et al. conducted research on the postoperative outcomes of LASIK in astigmatic patients.

The results, published in Investigative Ophthalmology & Visual Science, showed LASIK for astigmatism, even in severe cases, is often highly effective.

 

Can severe astigmatism be treated with Laser Eye Surgery?

You may have been told that you’re ineligible for Laser Eye Surgery due to:

  • Your level of refractive error (too shortsighted or too farsighted).
  • Source of your astigmatism — corneal, lenticular or both.
  • Extent of your astigmatic distortion.

But this may not necessarily be true.

Our surgeons routinely treat complex astigmatisms — patients with even 6 Diopters of astigmatism can expect excellent long-term vision outcomes.

Book your consultation with us, and your clinician will discuss all your available options in detail to determine the best course of treatment.

 

4 things to consider before you get Laser Eye Surgery

To determine if eye surgery for astigmatism is suitable for you, consider the following factors:

 

1) Your overall health

You may be ineligible for Laser Eye Surgery if you:

  • Have underlying health conditions, such as autoimmune disorders and uncontrolled diabetes.
  • Are pregnant, as pregnancy could affect the shape of your cornea.
  • Have had previous eye surgery, as you’re at higher risk for complications.

Discuss these and any other potential risk factors with your clinician during the consultation.

 

2) The expertise of your surgeon

An experienced surgeon will have a thorough understanding of the techniques used in Laser Eye Surgery. They can identify and manage any vital decision making or complications that may arise during the procedure.

A skilled surgeon is crucial in ensuring the best possible outcome for your treatment.

 

3) Calibre of technology

Which is more important? The laser or the diagnostic equipment?

The laser makes precise, controlled changes in shape of your cornea — any inaccuracies or imprecisions could result in suboptimal outcomes or complications.

And diagnostics provide critical calculations necessary for your procedure.

So, it is impossible to have one without the other.

That’s why we place equal importance on both — and have worked with WaveFront to develop our diagnostic and therapeutic equipment to match our rigorous standards.

This is the best way to have precise control over every aspect of your treatment.

 

4) Cost of the procedure

Laser Eye Surgery cost may vary greatly depending on the procedure, the location and the surgeon.

But here are some other factors you should look for in your treatment:

  • Comprehensive pre-surgical assessment so you get the best treatment plan for your individual needs.
  • Experienced clinicians using cutting-edge equipment for advanced surgical precision.
  • Extensive aftercare with detailed advice and follow-up to ensure the best long-term visual outcome.
