The goal of this study is to collect more information about the safety and rate of visual distortions associated with TECNIS Toric intraocular lenses (IOLs), Models ZCT450, ZCT525 and ZCT600, which have already been approved by the US Food and Drug Administration (FDA). <br><br>To be eligible for this study, patients must have high corneal astigmatism in both eyes and must already be planning to have cataract surgery.
