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.
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.

What is astigmatism?

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 more...

What causes astigmatism?

Irregular Cornea. Astigmatism usually is caused by an irregularly shaped cornea. Instead of the cornea having a symmetrically round shape (like a baseball), it is shaped more like a football, with one meridian being significantly more curved than the meridian perpendicular to it. Astigmatism usually causes vision to be blurred or distorted to some degree at all distances. Read more...
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...

What does astigmatism mean?

Not spherical. Astigmatism means that the front window of the eye, the cornea, is not spherical. It is shaped like the side of an egg. Astigmatism is normal. Read more...

Normal finding. 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...

What is astigmatism and is it related to glaucoma?

Not usually related. Astigmastism usually applies to the shape or curvature of the front of the eye or cornea. It is usually correctable with glasses, contacts or refractive surgery. Glaucoma is a disease where there is damage to the nerve in the back of the eye. Occasionally, after glaucoma surgery, there may be increased astigmatism. Read more...
Can be. For example, after glaucoma surgery, some astigmatism can be induced by incisions in the cornea or sclera. But by itself, glaucoma does not typically cause astigmatism. Read more...

Hi doctors, was just wondering what is astigmatism in children?

Astigmatism. Means that the front surface of the eye is not perfectly spherical. In other words, more like the side of an egg than an orange. Most eyes have astigmatism. If one has significant astigmatism, the vision will be blurred and the person will need glasses or contact lenses to see well. Read more...

Can you tell me what is astigmatism. Does it have anything to do with glaucoma?

Different things. Astigmatism is a refractive error of the eye, typically either from the cornea or lens. It is typically corrected with either glasses or contacts. This is different from glaucoma. However, glaucoma and astigmatism can occur at the same time, especially after glaucoma surgery where incisions on the eye can change astigmatism. Read more...
Refractive error. Astigmatism is a measure of how "unround" the eye is. We tend to think that the eye is a perfectly round globe, but it actually is almost always at least a little oblong, like a rugby ball. The degree to which the front window (cornea) is oblong is measured in amount and angle of astigmatism (in which direction the ball is standing). Glaucoma has nothing to do with astigmatism.

What is astigmatism compared to other visual or eye problems?

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 more...
