Abstract
【Subjects and Methods】Subjects were 39 eyes of 39 patients (20 males and 19 females; mean age, 68.8±9.7 years) who were implanted with multifocal T-IOL (ACTIVEFOCUSTM SV25T3-6, Alcon). The T-IOL power was determined using the CT formula in all eyes at the time of surgery. We retrospectively examined the following: 1) comparisons of the preoperative corneal with-the-rule (WTR) and against-the-rule (ATR) astigmatic measurements obtained using the K and FRCyl values, and 2) comparisons of the postoperative astigmatism errors and the percentages of eyes that had achieved a refractive astigmatism error within ±0.50 D and ±1.00 D with both formulas.
