Opposite clear corneal incisions with cataract surgery improve pre-existing astigmatism
Paired opposite clear corneal incisions may have a significantly greater refractive effect and more stable surgically induced astigmatism for with-the-rule astigmatism correction compared with against-the-rule astigmatism correction, according to a study.Opposite clear corneal incisions (OCCIs) are one of a few options used to improve pre-existing astigmatism at the time of cataract surgery; however, there are varying reports on mean astigmatic correction, incision size and follow-up time.
