Abstract Details


Evaluation of the quantity and timing of rotation using single peace hydrophobic acrylic toric intraocular lens (IOL) postoperatively.



Department of Ophthalmology, Dokkyo Medical University, Tochigi, Japan.


This study is a retrospective study. Cataract surgerys with implantation of TECNIS® Toric IOLs (Abbott Medical Optics) were performed to 60 eyes (51 people) by a same surgeon. Excluded criteria is other ophthalmic diseases and irregular corneal astigmatism. Refractive value was measured using auto refractometer (KR-8800, TOPCON), and astigmatism, visual acuities were measured preoperatively and 1 day, 1 week, and 1 month postoperatively. Quantity of rotation from target axis was measured immediately on the end of surgery, 1 day and 1 month postoperatively. Paired t-test, Student’s t-test, Dunnett's test and Tukey's test was selected for statistical analysis.


The mean quantity of corneal astigmatism at preoperatively, 1 day, 1 week and 1 month postoperatively are 1.32±0.50D, 0.83±0.53D, 0.71±0.54D, 0.54±0.46D respectively. Astigmatism were decreased on all selected period after surgery (P<0.01). Quantity of rotation for the target axis at the end of surgery, 1 day and 1 month postoperatively are 1.97±1.95°, 7.10±7.10°, 7.67±7.48°respectively. The significant rotation was recognized between the end of surgery and 1 day postoperatively(P<0.01).


The significant rotation of the toric IOL occurred within 1 day after surgery. To increase the accuracy of toric IOL, prevention of rotation light after the surgery.
