Vision impairment can interfere with the most basic tasks, making daily responsibilities difficult for those with poor eyesight. While glasses and contact lenses can effectively enhance vision for patients with refractive errors, they may not be ideal. Many people desire a more permanent and convenient solution.
LASIK surgery corrects abnormalities that cause vision impairment to improve vision and drastically reduce a person’s reliance on prescription lenses. Our Salt Lake City, UT, patients often ask Dr. David Masihdas about LASIK for astigmatism. Just like myopia and hyperopia, astigmatism is a refractive error that can be corrected through LASIK treatment.
What Causes Astigmatism?
Astigmatism is a refractive error that typically affects both near and far vision. When someone suffers from astigmatism, their vision is likely to be blurry, whether they are trying to focus on close-up objects or those at a greater distance.
Astigmatism is caused by irregularities with the cornea. Specifically, in individuals with astigmatism, the cornea is asymmetrical. Rather than having a nice rounded curvature, like a ping pong ball, a cornea that causes astigmatism will be curved more like an egg or football. This irregular shape makes it difficult for light to focus precisely on the retina.
LASIK surgery is an effective solution for our Salt Lake City patients who suffer from astigmatism. LASIK allows Dr. Masihdas to reshape the cornea and improve its curvature. By making minor adjustments to corneal tissues, Dr. Masihdas can make it possible for the retina to properly focus light so that the patient can see clearly at both near and far distances.
Dr. Masihdas offers blade-free and wavefront LASIK at his practice. Both of these techniques use a precise and powerful laser to create a flap on the top surface of the cornea. Dr. Masihdas lifts this flap and uses a second laser to make necessary adjustments to corneal tissues. When treating astigmatism, the goal is to create a more symmetrical and rounded curve. Once adjustments have been made, the flap is lowered. Tissues will heal on their own, so no sutures are needed.
Most patients notice an immediate improvement in their vision following LASIK, but it can take several weeks for vision to stabilize and the full effects of surgery to become apparent. Patients may experience side effects such as dry, red, itchy eyes while they recover from LASIK, but these tend to be mild and should resolve in a timely manner.
