Pronounced astigmatism -- a common vision impairment that results from an irregularity in the curve of the cornea (the curved, transparent dome of tissue through which light first passes on its way into the eye) and causes blurred vision -- develops in some individuals after cataract surgery because of swelling of the tissue or tight stitches (if stitches are used) that pull on the cornea and distort its shape. After the eye has healed from the operation, swelling diminishes and any stitches may be cut. This usually corrects the astigmatism. In some people, cataract removal can relieve existing astigmatism, as incisions may be designed to adjust the cornea's shape
