Treating Astigmatism with Our Eye Doctor in Colleyville, TX
Having good eyesight is something many people take for granted, and some people believe that the only problems they need to watch out for in their vision, or their children's vision are nearsightedness or farsightedness, but there is another related issue seen frequently at Advantage Eyecare in North Richland Hills, TX that needs to be addressed; astigmatism, which causes a distortion of vision, as well as other issues.
What is Astigmatism?
Astigmatism is a refractive error, most often caused by an irregular shaped cornea, not a disease of the eye. There is a problem with the way the eye focuses light. Light can't come into a single focus on the retina, instead, there are multiple focus points in front of and/or behind the retina, which results in distorted vision. Unlike nearsightedness or farsightedness, the distortion caused by astigmatism is not dependent on distance but can occur for images at both close as far ranges.
Ideally, the cornea should be a spherical shape, which has meridians that are supposed to be vertically and horizontally symmetrical from one another.
Corneal astigmatism, one side is more curved than the other, throwing vision off balance.
Lenticular astigmatism, a variation of the shape of the lens inside the eye can also occur, although it is less frequent.
Also, about 90% of astigmatism cases are regular astigmatisms, which involve perpendicular meridian and are signified by the front surface of the eye being football shaped. When irregular astigmatism happens, it is often due to scarring on the cornea, which can happen during surgery, or an eye disease that causes thinning corneas.
Three Types of Astigmatism
Myopic Astigmatism - One or both principal meridians are nearsighted, if both they are nearsighted to differing degrees
Hyperopic Astigmatism - One meridian is farsighted to a different degree than others in the eye
Mixed Astigmatism -One meridian is nearsighted, the other is farsighted
Risks of Not Correcting Astigmatism
People who suffer from astigmatism are more likely to squint, or experience, eye strain, eye fatigue, or have headaches in addition to the blurring and distortion of what they see. Activities, such as driving or operating machinery, become unreliable.
For children who have astigmatism, the risks are greater since the eyes and their relationship to the brain is still in development. Many experience educational problems, less skill in sports, and social issues. Uncorrected astigmatism can also lead to lazy eye in children.
Fortunately, identifying and correcting astigmatism is usually very standard at Advantage Eyecare, as it is found with a routine eye exam. Once identified, it can astigmatism can usually be corrected with eyeglasses, contacts, or refractive surgery, including LASIK.
