This study is to evaluate the necessity of considering posterior corneal toricity on refractive outcome of patients with cataracts and corneal astigmatism after implantation of intraocular lenses.
This is determined by comparing total corneal and refractive astigmatism,and by comparing the expected refractive result with actual refractive astigmatism postoperatively,using total corneal and anterior corneal astigmatism to calculate respectively.
417 studies on the registry are indexed under Astigmatism; 50 are open to participants now.
This study's planned enrollment of 30 is below the median of 55 across 325 interventional studies indexed under Astigmatism.

After topical anesthesia with Alcaine, 3.0-mm clear corneal incisions were made. Torsional phacoemulsification was performed using the Infiniti Vision System with the OZil handpiece, a 45-degree Kelman miniflared tip, and DuoVisc viscoelastic (all from Alcon).
Total corneal astigmatism is obtained by Pentacam at every visit.
