astigmatism in cataract surgery

Astigmatism occurs when the cornea or lens are shaped more like a rugby ball - longer in one direction than the other. This means that the image at the back of your eye isn't as sharply focused. 

I assess each eye prior to cataract surgery and aim to reduce astigmatism by a combination of selected placement of the surgical incision and additional incisions, called limbal relaxing incisions, if necessary. In some cases I use special astigmatic or toric intraocular lenses in place of the standard lens for additional anti-astigmatic effect. Low post-operative astigmatism is necessary if multifocal intraocular lenses are to be used.
