A toric IOL ( 1.25 D , 2.00 D , or 2.75 D , determined by a toric calculator ) was implanted in eligible patients with age-related cataract requiring a 16.00 to 27.00 diopter ( D ) spherical IOL power and with a predicted postoperative astigmatism of 0.83 to 2.50 D. Eyes within the lowest cylinder range ( predicted postoperative astigmatism 0.83 to 1.32 D ) were randomized in a 1:1 ratio between the 1.25 D toric IOL group and the nontoric accommodating IOL ( Crystalens ) control group .
