A toric IOL ( @ D , @ D , or @ D , determined by a toric calculator ) was implanted in eligible patients with age-related cataract requiring a @ to @ diopter ( D ) spherical IOL power and with a predicted postoperative astigmatism of @ to @ D. Eyes within the lowest cylinder range ( predicted postoperative astigmatism @ to @ D ) were randomized in a @:@ ratio between the @ D toric IOL group and the nontoric accommodating IOL ( Crystalens ) control group .
