Corneal irregularity
(Astigmatism)

Astigmatism is a condition that affects the shape of your eye. It is a common type of refractive error. Astigmatism is a condition in which the eye does not focus light evenly onto the retina, the light-sensitive tissue at the back of the eye. The symptoms can be: disorted or blurry vision at all distances.

HOW DOES ASTIGMATISM OCCUR?

Astigmatism occurs when light is bent differently depending on where it strikes the cornea and passes through the eyeball. The cornea of a normal eye is curved like a basketball, with the same degree of roundness in all areas. An eye with astigmatism has a cornea that is curved more like a football, with the some areas that are steeper or more rounded than others. This can cause images to appear blurry and stretched out.

Some patients with slight astigmatism will not notice much change in their vision. A patient with stronger astigmatism would be affected by blurry vision. This could lead to symptoms like: headaches or burning eyes sensation.

Astigmatism can be corrected with eyeglasses or contact lenses; alternatively it can be corrected with an eye laser surgery. The refractive surgery could be the opportunity to completely get rid of your glasses or contact lenses. Eye laser surgery or on the other hand, lens implants could be a solution.

Care Vision offers 2 laser eye procedures: LASIK and PRK/LASEK

ASTIGNATISM TREATMENT

 

LASIK stands for Laser-Assisted In-Situ Keratomileusis and has been in use since 1990. The first step is to administer anesthetic eye drops. Step two is to prepare the uppermost layer of cornea, the so called flap (corneal lamella), with the microkeratome. Subsequently, the laser is in use for a few seconds, and then the flap is returned to its original position. 

The second treatment option is the PRK/LASEK method. This is also a short and painless procedure.

Which method is used for the correcting of astigmatism depends on the structure of the eye as well as the personal circumstances of the patient. Since for the PRK/LASEK method, no flap is necessary, this treatment is particularly suitable for martial artists and police officers.
