What are different types of eye surgery astigmatism?

Astigmatism of eye surgery, also called refractive or laser eye surgery, concerns several types of surgery that transform the cornea, a clean front surface of the eye when it has abnormal curvature. Abnormal curvature or astigmatism either corneal or lenses immediately behind it cause blurred vision. The aim of each type of eye surgery is to correct the irregularly shaped cornea or lens, allowing the light to pass through the cornea so that the retina placed correctly located in the rear of the eye. Different types of eye surgery can be recommended depending on the degree of astigmatism present. Different types of eye surgery include laser assisted in situ keratomileusis (lasik), photorefraction keratectomy (PRK), laser epithelial keratomileus (lasek), laser thermokeroplastic (LTK) and astigmatic corretomas (AK). A common type of eye surgery astigmatism, astigmatism is corrected by transforming the corneal tissue so that it can properlydirect the light into the eye and back to the retina. The corneal tissue is transformed by scratching a high -focused laser beam of light. Then a flap is formed in the outer layer of the cornea, so it is possible to approach the underlying tissue. Lasik eye surgery is very effective for people who are short -sighted and far -sighted, as well as people with astigmatism.

Surgery is a type of laser eye surgery that is used to repair mild to medium astigmatism, nearsightedness and foresight. During this type of laser surgery, the surgeon transforms the surface and inner layers of the cornea with the pulsating beam of ultraviolet light. There is no need for cutting during photorephractive keratectomy.

Surgery is a newer form of surgery of astigmatism of astigmatism, which is used to treat astigmatism, nearsightedness and foresight. There is no scratching or Ř during the Lasek procedureEye of the eye. The epitheal valve is created with a 20 % alcohol solution that removes a small amount of corneal tissue by evaporation.

ltk surgery is a type of non -contact surgery of the refractive eye of the laser, which is used to treat astigmatism and foresight. During the LTK surgery, the laser beam shrinks and transforms the cornea in seconds, without any cutting or removing the corneal tissue or lens. It is a quick procedure, but LTK is not a permanent laser eye surgery, because the eyes are changing with age. Finally, further operations may be required.

and surgery is a surgery used to remedy astigmatism rather than for the form of laser eye surgery. One or two slices are performed in the steepest part of the cornea during AK surgery. The cornea is then released and has a rounder shape. Refractive eye surgery AK can be used separately or in conjunction with EYE Laser Operation.
