No, lasik surgery is one of the effective way to cure astigmatism. The way in which surgeons correct astigmatism through LASIK is by flattening the steeper curve of the cornea. This helps to decrease the cornea's oblong shape and creates a more spherical form. In the procedure, laser pulses are precisely delivered to corneal tissue in the axis of the steeper curve. By decreasing the angle of the sharper curve and contributing to the overall spherical shape of the cornea, LASIK surgery enables the eye to focus light rays more efficiently, resulting in clearer, crisper vision.
One of the many benefits of laser eye surgery is that it is the only treatment available for astigmatism that actually addresses the source of the problem rather than simply treating the symptoms.
