Is LASIK For Astigmatism? - Kugler Vision
Have you been told you are not a candidate for LASIK because you have astigmatism? It’s time for a second opinion! Our mission is for everyone to achieve their best possible vision, so they may feel confident and live life with energy and vitality. We are committed to empowering our patients with the best vision scientifically achievable.
One of the most common myths about LASIK surgery is that it cannot be offered to patients with astigmatism. Although this was true over 20 years ago when LASIK technology was in its infancy, it is no longer the case. Modern laser systems can treat astigmatism very well! At Kugler Vision, Lance Kugler, MD is an expert in the analysis and treatment of astigmatism.
Astigmatism means that the eye is not perfectly round, like a basketball, but rather is irregularly shaped, like an American football. Astigmatism affects 50-75 percent of the general population and most patients with astigmatism are aware that they have it. However, there are many patients who have subtle forms of astigmatism that cannot be detected without advanced astigmatism
Watch as Dr. Kugler discusses Astigmatism on WOWT Channel 6, MomsEveryday in Omaha:
The cornea, or front-surface, is the structure of the eye that is most often responsible for astigmatism. Other structures within the eye, such as the posterior surface of the cornea or the crystalline lens, may also contribute to astigmatism.
Laser vision correction, like LASIK, changes the shape of the front surface of the cornea. Therefore, if astigmatism is confined to the front surface of the cornea, then laser vision correction is very successful in correcting blurry vision.
If the astigmatism is elsewhere in the eye, then laser vision correction may cause poor quality vision long-term. Avoiding long-term astigmatism requires special expertise in “vector analysis”. Advanced astigmatism analysis using vectors increases the long-term success of laser vision correction. In fact, Kugler Vision is one of only a few practices in the world actively using vector analysis software for all LASIK patients with astigmatism.
