Astigmatism is a refractive error of the eye, the cornea is irregularly shaped causing aside. The irregular shape of the cornea changes the way light rays are refracted, and then be focused on the retina of the eye 's.
There is no harm in your field of vision, such as the blurring of the lines marked. Astigmatism is another presentation of the development of eye strain and headaches, especially during prolonged reading.
Treatment canbe surgical or nonsurgical. The non-surgical treatment involves the use of corrective lenses. Surgical treatment of astigmatism, the other face of refractive eye surgery.
corrective lenses
The conservative approach for the treatment of astigmatism is about the use of corrective lenses. This corrective lenses are able to counteract the irregular shape of the cornea. Corrective lenses involving the use of glasses and contact lenses. Another process, known asOrthokeratology, or ortho-K, make use of contact lenses to change the shape of the cornea. Ortho-K requires the use of the lenses only at night. Thus the shape of the cornea is changed gradually.
Refractive
Refractive surgery is the treatment for permanent use. Change the shape of the eye permanently. There are several types of corrective eye surgery that can be used in the treatment of astigmatism.
Firsta process known as AK or astigmatic keratotomy, was used to cut the cornea of the patient to change their shape. But with the advent of excimer laser refractive eye surgery and new techniques, the use of AK has decreased significantly. Newer techniques of refractive eye surgery might reduce the risk of complications and have produced better results, so they are convenient for both ophthalmologists and patients.
TodayLASIK refractive eye surgery is the most common used in treatment. LASIK involves creating a corneal flap with an excimer laser to reshape the cornea of the eye 's. Another refractive eye surgery PRK is used to treat astigmatism, with only the surface of the eye removed. However, PRK is more commonly used. One of the new types of refractive eye surgery is LASEK with a thin layer ofCornea under open, the laser ablation of the layers as they can.
It can be treated adequately with both non-surgical and surgical techniques. Ask your eye doctor about the risks and benefits of various options.
