LASIK (Laser-Assisted In-Situ Keratomileusis) surgery is a procedure that corrects vision problems that are rooted in focusing errors. These include farsightedness, nearsightedness and astigmatism. LASIK surgery reshapes a part of the eye to allow a more efficient refraction of light and processing of images. It is performed by trained professionals who specialize in eye surgeries and vision correction. If you are looking for LASIK doctors Houston has a number of specialists in the field. Learn more about what LASIK is, how it works and if it is a good option for astigmatism.
What is Astigmatism?
Astigmatism is a condition that affects vision, resulting in blurry images. It is caused by irregularity in the shape of the cornea, which is the transparent part of the eye in front. A normal eye is shaped like a volleyball, round and even, while an eye that has astigmatism is shaped like a football. The abnormality in the shape of the eye affects how light is refracted, resulting in distorted images.
To correct astigmatism, a portion of the cornea is operated on during eye surgery. The cornea protects the anterior chamber, pupil and iris. It is one of the components of the eye that refracts light and plays a key role in the overall optical power of the eye. Any irregularity in the shape of the eye affects how an image is processed in the brain.
Astigmatism can occur in both nearsighted and farsighted individuals. It is also fairly common – many people with vision problems have some degree of astigmatism.
Symptoms of Astigmatism
People with astigmatism may experience one or a combination of the following symptoms:
- Blurry, fuzzy or distorted images regardless of distance from the eyes
- Eye discomfort, irritation or eye strain
- Squinting
- Poor night vision
- Headaches
How Can LASIK Help?
LASIK surgery is one of the more popular types of refractive eye surgeries designed to correct vision. It utilizes concentrated pulses of light in the form of laser to vaporize a targeted portion of the cornea called the stroma. Removing minute amounts of the tissues at the site will re-shape the cornea and correct vision.
LASIK surgery works best for individuals who suffer from mild to moderate astigmatism. Although it can be an excellent option for vision correction and allow the patient to reduce or even eliminate his or her dependence on prescription eyeglasses and contact lenses, it may not be recommended for everyone who has astigmatism. Some patients, for example, may have other conditions that may not make LASIK surgery a feasible option. Ultimately, the decision whether or not you can undergo astigmatism and vision correction through LASIK surgery rests on you and your doctor.
