Astigmatism lasik surgery to cure astigmatism
Summary: a high degree of success is achieved through astigmatism lasik surgery and being a painless and quick process, is highly desirable.
Treatment of astigmatism is possible through astigmatism lasik surgery, which uses zyoptics wave front technology. It is important that the laser treatment be delivered at the exact angle so that it is effective. A 6.0 D correction is possible by astigmatism lasik surgery. Astigmatism is usually found along wit short sightedness or far sightedness. Since the cornea of the eye is not perfectly circular as it should be, people suffering from astigmatism have difficulty in seeing vertical, horizontal or diagonal lines. The shape of the cornea determines if one has short sightedness, far sightedness or astigmatism. A person with astigmatism up to 5.0 Dioptes can be treated using astigmatism lasik surgery, which can treat the areas of blurry vision in the cornea. The precision of the excimer laser and lasik are used to alter the shape of the cornea in astigmatism lasik surgery so that light gets properly focused or refracted by the eye.
Surgical procedure:
The use of anaesthesia in the form of eye drops ensures that there is no pain during the surgery. An instrument called a microkeratome glides across the cornea so that a thin layer of the cornea may be lifted. Next, an excimer laser is used to beam ultraviolet laser pulses, which will help reform the internal cornea with accuracy levels up to 0.25 microns. Adjustments of the laser beam with the assistance of a computer make it possible to treat high levels of astigmatism. After the tissue is reshaped, the flap is replaced in its original position and allowed to heal without any stitches.
The entire procedure takes less than half an hour and so, is often performed as an outpatient procedure. This is also a relatively painless surgery though there may be some discomfort a day after the astigmatism lasik surgery.
