Degrees Of Astigmatism
How much degree of astigmatism is ignorable? I have -0.50 cyl, ax 111 in right and -0.50 cyl, ax 92 in left. Should i get correction for this?
To what degree can a lensectomy correct astigmatism? I have heard that a lensectomy can correct astigmatism. I'm excited about this since my condition rules out laser corrective surgery. Is this an effective treatment for astigmatism? Am i likely to still
Yes and no......: Astigmatism can be caused by both your lens and your cornea. Usually, most of it is caused by your cornea. If you remove your lens you would need to replace it with an aritifical lens, preferably with a toric implant to offset the corneal astigmatism. This is called refractive lens exchange. Lensectomy just removes your lens, which may rarely remove astigmatic lens but leaves you very blurry. ...Read moreSee 1 more doctor answer
Oval eye shape: Refractive errors require either plus (farsighted) or minus (nearsighted) glasses + an extra amount if the eye is oval in shape (astigmatism). These are called refractive errors and can be corrected with glasses or contacts. The list of other eye problems is long and these are usually unrelated to astigmatism. ...Read moreSee 1 more doctor answer
Corneal curvature: Astigmatism just means that your cornea is not perfectly spherically shaped and instead has different curvatures in different directions (kind of like a football in the extreme example). Everyone has some degree of astigmatism although not everyone has enough to notice it. I doubt you "need" any surgery. ...Read moreSee 1 more doctor answer
Usually not: Astigmatism is a physical curvature aspect of the cornea and lens of the eye which in effect makes the eye oval. The term astigmatism is from physics and is not usually a bad thing. The correction is a reverse oval in the eyeglasses or contacts. Most astigmatism is small and easily corrected. Sometimes it is large or irregular and that make perfect vision difficult. See your ophthalmologist. ...Read more
