What is astigmatism - What is Definition Of Astigmatism

What is astigmatism - Myopia or hyperopia are widely known optical defects, one involves see evil from afar and the other worse, but, astigmatism, is what exactly?

When a person suffers this ametropia (default view) what happens is that the curvature of your cornea is not the same throughout the area, i.e., has irregular areas. The Mission of the cornea for vision is extremely important. It is in charge of refract light so that the image that we are looking at projects in the retina, and once there, thanks to the photoreceptor cells, light is transformed into nerve impulses. Then through the optic nerve, these impulses are transferred to the brain.

What is astigmatism - What is Definition Of Astigmatism

If you have astigmatism, having asymmetric surface of the cornea, the light is refracted evil, causing you to make images look distorted both by far and closely. The difference with myopia and hyperopia is that they usually occur due to a defect in the size of the eyeball, and this causes that, or good image to project at a point prior to the retina (myopia), or in a posterior (hyperopia).

The cornea may be the perfect curvature, but having the eye too small or too large, equally produced errors in refraction and causes poor vision. A short-sighted person will only see evil from afar, and a long-sighted, closely. These two defects may not suffer simultaneously from, are mutually exclusive from each other, but the astigmatism is completely different, may be the only fault of the eye or may occur along with a farsightedness or nearsightedness.

As in any ametropia, there are different degrees of condition, and not all require treatment. Very mild astigmatism may be asymptomatic, i.e., does not show any detectable complication and own eye corrected the vision involuntarily without discomfort for sufferers it.

If it is more pronounced, appear symptoms such as headache, dizziness and difficulty to focus. According to the degree these nuisances will be more or less intense. There are several formulas to correct it: contact lenses, glasses, surgery... The specialist will advise us what is the best remedy.

Types Of Astigmatism - What Are Differents Type Of Astigmatism

Types Of Astigmatism - Astigmatism is a refractive error which makes vision blurred in some degree at any distance. Many people who suffer from myopia (commonly referred to as short-sighted) or hyperopia (known as hyperopic) also have astigmatism, while others only have astigmatism.
Astigmatism is caused by an irregularly shaped cornea. Instead of being round perfect, like a basketball ball, a corneal astigmatic has elliptical shape, more like a rugby ball.

Types Of Astigmatism - What Are Differents Type Of Astigmatism

The light passing through an astigmatic cornea can not focus on a single point on the retina, but it focuses on several points, what makes it impossible for the eye to focus a clear image.
The majority of people with astigmatism using glasses or contact lenses to achieve a better view. Glasses and contact lenses are effective for the majority of people, they are not always ideal for everyone. Among the disadvantages of carrying glasses or lenses are the possibility of that loss or breakage, the discomfort of carrying them and in the case of the glasses, the change in physical appearance.

Types of astigmatism

There are several types of astigmatism:

• Myopic astigmatism: occurs when either of the two principal meridians of the eye is myopic (where are both, should be in different degrees).
• The hyperopic astigmatism: in this case, one or both main meridians are hyperopic (where are both, should be in different degrees).
• Mixed astigmatism: A Meridian is short-sighted, and the other is hyperopic.

Astigmatism is also classified as regular or irregular. In regular astigmatism, the principal meridians are separate 90 degrees (perpendicular to each other). In irregular astigmatism, the principal meridians are perpendicular. The majority of corneal astigmatism is regular astigmatism (eye gives a form of football).
Regular astigmatism is usually also differentiate into 3 types.
Astigmatism direct (or according to the rule): the vertical Meridian is more pronounced (looks like a rugby ball)
Astigmatism reverse (or rule): the horizontal Meridian is more pronounced (looks like a rugby ball but vertical)
Oblique astigmatism: the angle of the curve is between 120 and 150 degrees and between 30 and 60 degrees.
Irregular astigmatism may appear due to a lesion in the eye causing scarring of the cornea. Also from certain types of eye surgery or by Keratoconus, a disease that causes a gradual thinning of the cornea.

Lasik For Astigmatism

Lasik For Astigmatism - LASIK, which means "Laser-Assisted In Situ Keratomileusis" ("Keratomileusis in situ laser-assisted") is a treatment of astigmatism that uses an excimer cold laser to give shape to the cornea so that you can properly focus images on the retina. The LASIK procedure is to cut a small flap in the cornea flap and move it to one side before returning to give shape to the underlying tissue.

Lasik For Astigmatism

The cornea heals quickly and many patients notice a significant improvement in vision from the first day of recovery. Because of its short period of recovery and practicality (is an outpatient procedure that usually take only 10 to 15 minutes), LASIK is the most common refractive surgery. Another innovation in the treatment of astigmatism is custom LASIK or LASIK surgery Wavefront ; This procedure takes three-dimensional measurements of the way in which her eyes processed images and uses them to guide the laser during surgery. This method is much more accurate than traditional LASIK, and treatment is to correct the astigmatism of more accurate than glasses or contact lenses.

Eye Astigmatism - What Is Eye Astigmatism

Eye Astigmatism - Astigmatism is an is a usual common refractive error which arises as a result of a flaw in the curvature of the eye. In the normal eye, the cornea (the front part of the surface of the eye) and lens are even and uniform in all directions. Eyes with astigmatism, the cornea or the lens have an irregular shape in some areas, causing blurred vision. Astigmatism is not an eye disease; It simply consists of a variation in the shape of the eye. A person may have astigmatism of moderate to severe depending on the amount of irregularities of the cornea or lens. If you want more information about the causes of astigmatism, symptoms and diagnosis, continue reading on the following pages.

If you have any of these symptoms, you should contact a qualified ophthalmologist to undergo a comprehensive eye exam.

In an eye with perfect form, the cornea enjoys a curvature evenly and smoothly and has the shape of a round ball. Eyes with astigmatism, the cornea has a more oval (like an American football); that makes spreading the light over. The result is a blurred image on the retina which makes it difficult for persons with astigmatism vision at any distance.
