Astigmatism is a very common condition affecting one in three people. Even though astigmatism is such a prevalent condition, it is still extremely misunderstood. For example, did you know that LASIK surgery is used for astigmatism correction? Not everyone with astigmatism will be considered a good candidate for LASIK, but it’s worth it to find out.

If we liken the shape of the cornea to balls used in sports, those with astigmatism have football-shaped corneas, while a normal cornea is baseball-shaped. Due to the difference in the shape of the cornea, light is refracted – or bent – differently as it enters the eye. The result is the sensation of blurry or distorted vision.
There are two types of astigmatism. The most common type is referred to as regular astigmatism, which affects about half of the adult population. The second kind of astigmatism is called irregular astigmatism and is the result of keratoconus, an eye disease that results in gradual thinning of the cornea.
LASIK For Astigmatism Correction
Irregular astigmatism is not easy to treat with prescription eyeglasses, but contacts can be used as a treatment option in some cases. LASIK can be used as for astigmatism correction depending on the severity and type of astigmatism a patient may have.
LASIK or Laser-assisted in situ keratomileusis is one of the most commonly performed surgeries. A laser is used to reshape the cornea to correct refractive errors such as astigmatism. People with mild to moderate astigmatism tend to have the best results with conventional LASIK or Blade-Free LASIK, which is also known as custom LASIK. Your LASIK surgeon at Feinerman Vision Center will examine your eyes to determine what kind of astigmatism you have, and which type of LASIK surgery is the best option for you.
How Will My LASIK Surgeon Decide If LASIK Is Right For Me?
The process to qualify for conventional LASIK or blade-free LASIK is strict, requiring several tests that are run on your eyes. If you are being considered for custom LASIK, your eyes will be checked for both higher and lower order aberrations (such as blurring, halos, distorted vision), as well as measuring the thickness of your cornea. Since LASIK surgery removes corneal tissue to reshape it for vision correction, this is one of the most important parts of the approval process for undergoing conventional or blade-free LASIK. The results of these tests will help your LASIK surgeon determine which vision correction surgery is the best option for you.
The Benefits Of Blade-Free LASIK
In conventional LASIK, the flap in the cornea is created by your LASIK surgeon with a blade called a microkeratome. Although very rare, it is possible for the flap to be made irregularly, resulting in complications. Blade-free LASIK creates the flap, reducing the small chance of an irregular corneal flap. Regardless of the benefits, your LASIK surgeon will determine which option is best for you. Call our office for a free consultation with Feinerman Vision Center today!
