Repositioning technique and rate for toric intraocular lenses.

I previously reported the excellent rotational stability of the AcrySof toric intraocular lens (IOL) (Alcon, Inc.) in a consecutive series of my first 100 cases. Ninety percent and 99% of the IOLs were aligned within 5 degrees and 10 degrees of the intended axis, respectively, and no IOL required surgical repositioning. I compared the results in this series with those in my retrospective series of 90 consecutive Staar toric IOLs using an identical surgical technique. The mean IOL rotation was 3.35 degrees G 3.41 degrees in the AcrySof group and 5.56 degrees G 8.49 degrees in the Staar group (P Z .0232). By the end of 2008, I had implanted 263AcrySof toric IOLs. Three of the IOLs had rotated more than 15 degrees off axis, and all 3 required surgical repositioning,
