What Are The Allopathic Treatments Suggested For Astigmatism?

The most common allopathic treatment for astigmatism is the use of either power glasses or contact lenses. The lens works in the principle of counter-reacting with the shape of the cornea in order to facilitate the visionary abilities. The contact lenses that are particularly used in treating astigmatism are called toric lenses. In case of keratoconus, a surgery may be employed in order to cope up with the problem.

In considering the surgical method, the refractive surgery is the most common mode to be employed. Primarily there are two types of refractive surgeries –

• Radial keratotomy (RK) in which intersection is made in cornea to rectify the shape by using diamond blade instrument.

• Photoreactive keratotomy (PRK) in which the micro-thin slices of the cornea are removed in order to shape the cornea by using a laser.

The most advanced technique used in treating astigmatism is Laser Assisted in situ keratomileusis (LASIK) in which a flap of the cornea is removed using laser in order to improve the shape of the corneal tissue.

Anyone who undergoes for LASIK therapy must consider the effectiveness and expertise as well as knowledge of the surgeon in question. The possible outcomes and side-effects may also be evaluated through a proper and methodical discussion prior to the surgical intervention.
