Evaluation of the Accuracy of Two Marking Methods and the Novel toriCAM Application for Toric Intraocular Lens Alignment

It has been shown that approximately 30% of patients undergoing cataract surgery have corneal astigmatism of more than 0.75 diopters (D).1 Postoperative residual astigmatism decreases unaided visual acuity and quality of vision.2 A better understanding of the effect of posterior corneal astigmatism3 and the availability of more accurate toric intraocular lens (IOL) predictions have improved the ability to correct astigmatism with toric IOLs during cataract surgery, even in patients with low preexisting cylinder.4 Toric IOLs need to be positioned accurately on the intended meridian to have
