One of refractive disorders and the most frequent common in patients suffering from hyperopia and myopia , astigmatism is a condition characterized by blurred vision and which is caused by an abnormality in tissue morphology of the cornea , which can be processed by a laser assisted corrective surgery .
A common vision related disorder , astigmatism is a condition caused by an abnormal growth of the cornea, the natural lens of the eye, which , by its irregularities causes blurry, distorted vision, and in some cases , vision, eyestrain and headaches. In addition, if astigmatism usually appears along with other refractive errors such as myopia and hyperopia , the disease responds well to laser eye surgery .
In recent decades , patients with this condition have started to prefer laser eye surgery to the traditional use of corrective lenses and treatment of astigmatism contact lenses , mainly because it is a procedure ambulatory , which implies a minimum risk and low postoperative discomfort .
Although astigmatism is like myopia hyperopia and loss of visual acuity, this condition is much more complex than the other two spherical refractive errors , both in magnitude and direction , which is why , astigmatism it is more difficult to correct with glasses and contact lenses .
The complexity of this is provided at the front or back of the corneal tissue , and is due to an asymmetry of the eye structures . However , astigmatism appears after a traumatic injury to the tissue of the cornea and , after growth of keratoconus .
Currently, many patients with refractive deficiencies , including astigmatism turn to corrective eye surgery laser to improve your visual acuity and return to a normal life - glasses free. , Advanced technology allows our century ophthalmologists worldwide by solving high refractive anomalies , which often can not be solved by glasses and contact lenses , thus restoring normal vision to patients suffering from astigmatism a relatively painless way safely .
Perhaps the most common corrective eye surgery LASIK laser -assisted type, which means in situ keratomileusis laser-assisted , is a very popular procedure for patients with astigmatism . The procedure involves making an incision in the ultra - thin in the epithelium of the cornea, and then , using an excimer laser vaporization stromal tissue malformed below to convert the perfect corneal refractive lens thereby improving sight.
Although LASIK is the most popular procedure that helps patients suffering from refractive errors , including astigmatism , there are many other types of eye surgery (PRK , LASEK , LTK and ALK ) before s' install on a particular procedure, the patient must first consult an ophthalmologist to choose the right treatment for your condition .
