How does astigmatism threaten homeostatis of the organ system(s)?

Blurry vision: Astigmatism just means that the i does not focus light at a single point. The result is blurred vision unless the astigmatism is corrected. Classic complaints of uncorrected astigmatism are ghosting of vision. ...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

What is astigmatism?

What is astigmatism?

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

What is astigmatism?

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

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

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

Can astigmatism be cured?

Can astigmatism be cured?

Yes: Astigmatism is an irregularity of the cornea that is generally treated with glasses or contact lenses. It can be surgically 'cured' with laser vision corrrection ( lasik or prk ) or incisional corneal procedures. ...Read more

How is astigmatism diagnosed?

How is astigmatism diagnosed?

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

Can a major astigmatism be fixed?

Usually: Astigmatism can be corrected with eyeglasses and special contact lenses. It can be diminished with lasik surgery in most cases. The key word here is "major". Discuss with your ophthalmologist what options would be best for you. ...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
