Astigmatism is a naturally occurring condition affecting many individuals in which the cornea is slightly oval, rather than round or spherical. While not a “disease”, astigmatism does lead to blurred vision, and must be corrected in order to see clearly. Traditionally, after cataract surgery with a basic implant lens, this correction was done with prescription eyeglasses in the form of bifocals.
There is now, however, a better way. Astigmatism can be corrected completely and permanently at the time of cataract surgery with a special, customized “toric” implant lens. Simple over-the-counter reading glasses will still be required, but patients choosing to correct their astigmatism with Toric Implant Lens will generally not need prescription glasses for driving, watching TV, or other distance needs.
