how is astigmatism treated?

Question

Answer 1

Contact lenses: The irregularities in the curvature of the cornea can be addressed though customized contact lenses.

Answer 2

Astigmatism: Astigmatism is where the surface of the eye is peaked like a football, instead of being smooth like a soccerball. Uncorrected astigmatism causes straight lines to appear wavy. It may be corrected with glasses, contact lenses, or refractive surgery. For people with significant cataracts, it may be corrected with a toric implant.

Answer 3

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).

Answer 4

Astigmatism: A complete eye exam can pick up astigmatism, since it is measurable in your glasses prescription. It can also be mapped using corneal topography, where a surface is made of your eyes.

Answer 5

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.

Answer 6

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.

Answer 7

Refractive Error: Here is a great article by mayo clinic: http://www.Mayoclinic.Com/health/astigmatism/ds00230/dsection=causes. Astigmatism has to do with distortions of the curves in the cornea or the lens of the eye.

Answer 8

Cornea, lens: In astigmatism, light that enters the eye is refracted more in one direction than the other, allowing only part of the object to be in focus at one time. 95% of the time, this is caused by differences in curvature in different axes of the cornea on the front of the eye. The cornea does 2/3 of the focusing of light in the eye. The other 1/3 is done by the lens, which causes 5% of astigmatism.

Answer 9

Astigmatism: Astigmatism occurs in about 60% of eyes. It is an ovalness of the eye corrected with a reverse oval in the eyeglasses and contacts. The degree is quite variable and most have a small amount but you need to see your ophthalmologist to have yours measured.

Answer 10

Very common: Small degrees are very common but are easily corrected with glasses. Big amounts can be difficult to correct but is less frequent.

Answer 11

It might: Almost all degrees of astigmatism can be corrected with properly prescribed eyeglasses or contact lenses. For a person with only a slight degree of astigmatism, corrective lenses may not be needed at all, as long as other conditions such as nearsightedness or farsightedness are not present. If the astigmatism is moderate to high, however, corrective lenses are probably needed.

Answer 12

It might: Almost all degrees of astigmatism can be corrected with properly prescribed eyeglasses or contact lenses. For a person with only a slight degree of astigmatism, corrective lenses may not be needed at all, as long as other conditions such as nearsightedness or farsightedness are not present. If the astigmatism is moderate to high, however, corrective lenses are probably needed.

Answer 13

You cannot: With the exception of certain eye diseases, most people's prescription, including astigmatism, is stable from the early 20s to the middle to late 40s and sometimes beyond. You can correct for this with glasses, contacts or laser vision correction.

Answer 14

Possible help: Sometimes hard contact lenses such as gas permeable contact lenses can provide a controlled physical contact against the cornea to slow progression of astigmatism. Avoid rubbing the eyes. New surgical techniques known as corneal cross-linking are under fda investigation with possible approval within a year.

Answer 15

Astigmatism: Unless your eye has an abnormality, your astigmatism should be stable. If your astigmatism us worsening, you should see a cornea doctor for further evaluation and treatment. Treatment would depend on the cause of the astigmatism.

Answer 16

See an Eye MD: If your astigmatism is changing, then you may have a corneal disorder. See an ophthalmologist for evaluation.
