How bad is astigmatism?

How bad is astigmatism?

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

Astigmatism (Definition)

An eye condition that causes blurry vision because the eye is unable to focus light to a point and thus unable to produce a sharp ...Read more

How bad is my astigmatism? O.D. -.5/+1.25/+175. O.S. -.5/+1.75/+172

Good/Bad in the eye: Of the beholder. Astigmatism simply means the focusing of the eye is not equal all angles around the central line of sight; more curvature one way than 90 degrees around. The +1.25 & +1.75 values in the ophthalmologist's Rx for correction is the astigmatism correction in diopters (1 = the curvature needed to focus parallel light rays to a point 1 meter away). Values >3-4 diopters=fairly high. ...Read more

Can you tell me is having astigmatism a bad thing?

Can you tell me is having astigmatism a bad thing?

Astigmatism: Astigmatism is one type of refractive error. Myopia (or nearsightedness), hyperopa (or farsightedness), and astigmatism all can cause refractive error. Refractive error is what causes a patient to require glasses or contact lenses to see better. Astigmatism is typically when the cornea is shaped more like a football than a basketball. Glasses, contact, and LASIK can fix this problem. ...Read more

Can you tell me if astigmatism gets so bad that even glasses won't correct them it?

Astigmatism: This is unusual but certainly is possible especially if the astigmatism is irregular in nature because of a problem with the cornea (window to the eye). If you are unable to be corrected with glasses, a visit with an ophthalmologist is valuable to determine if an medical condition exists that is causing your severe astigmatism. ...Read more

Do I need to wear glasses all the time if I have astigmatism (bad astigmatism)?

Why not contacts or: Contact lenses can treat high degrees of astigmatism as can toric intraocular lens implants. A specialist in astigmatic contact lens fitting may be needed. Clear lens extraction with a toric intraocular lens is controversial. ...Read more

It takes 20 times longer for my eyes to accomadote from bright to dim. Is my astigmatism that bad?

It takes 20 times longer for my eyes to accomadote from bright to dim. Is my astigmatism that bad?

No association: Astigmatism has no relationship to dark adaptation. Dark adaptation gets worse with age. If yours is much worse than similarly aged friends, then you should see an ophthalmologist to have it investigated. It could be a sign of a rare retina disease. (most cases turn out to be normal.). ...Read more

How do you suddenly have astigmatism in both eyes? Had bad reaction to topiramate about a month ago. Related?

How do you suddenly have astigmatism in both eyes? Had bad reaction to topiramate about a month ago. Related?

Puzzling: Topamax (topiramate) can cause swelling of the ciliary body in the eye which can cause the pressure to increase and to become very near-sighted. It is difficult to imagine a scenario in which it would cause or change astigmatism. These issues resolve with discontinuing the drug.

Discuss this with your ophthalmologist. ...Read more

I've had a severe astigmatism in my left eye. My right eye has a slight. Could it have something to do with my bad astigmatism?

Hard to tell: Need to see if astigmatism is changing. 'bad astigmatism' can occasionally represent keratoconus which is progressive change of curvature of cornea with eventual thinning. ...Read more

I have a lazy eye and at the same I have very bad astigmatism in the same eye. Can I get lasik eye surgery on it?

I have a lazy eye and at the same I have very bad astigmatism in the same eye. Can I get lasik eye surgery on it?

Yes, but: Lasik can only do what glasses or a contact lens can do. If you are happy with the vision with these choices, then lasik may provide similar vision without them. Discuss your options with an ophthalmologist. ...Read more

What is astigmatism?

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 more

What causes astigmatism?

Eye growth: Mosty astigmatism is due to the way the eye develops as it grows and is due to differential growth in one axis causing an ovalness of the need for glasses. Some astigmatism can also be from eye trauma. ...Read more

Diagnosing Astigmati: Astigmatism is caused by a football shaped cornea so technologies can that can measure corneal shape (topographers) can diagnose astigmatism.Glasses refraction, corneal topography, scheimpflug photography, keratometry, and many sophisticated technologies can easily diagnose astigmatism today. Most cases can be corrected by glasses/cls, laser techniquesand lens implant technologies (toric lenses). ...Read more

How to tell if I have astigmatism?

Most people do: Most people have astigmatism which is when the front of the eye is not a perfect sphere. With significant astigmatism, your uncorrected (without glasses or contacts) vision is blurred.

So if you don't have blurred vision, you don't have significant astigmatism. If you do have blurred vision, your eye doctor can tell you if it is due astigmatism or another cause. ...Read more
