Cataract

Astigmatism Reduction

What is astigmatism?

Besides nearsightedness and farsightedness, the third major category of refractive error is called astigmatism. This blur results from a cornea that is not perfectly spherical in shape, but rather football shaped.

Procedures such as LASIK, PRK or Limbal Relaxing Incisions can surgically reduce astigmatism by re-shaping the oblong curvature of the cornea. An astigmatism correcting IOL known as the Toric IOL can be implanted at the time of cataract surgery to reduce or eliminate astigmatism usually requiring only drug store reading glasses for near tasks after surgery.
