A hydrophobic acrylic Toric IOL (Tecnis Toric Abbott Medical Optics) is studied to determine its efficacy in correcting sphere and cylinder in patients presenting for cataract surgery.

A prospective non-randomized single surgeon, single centre study of patients presenting for cataract surgery with significant astigmatism. 598 eyes were enrolled and 557 completed the study. Post operative results were analyzed for the accuracy of both sphere and cylinder correction.

The median absolute error for sphere correction was 0.32 diopters (SD 3.9) and for cylinder 0.19 diopters (SD 0.28). These results were also stratified into with and against the rule astigmatism and will be presented. Outliers will be presented and reasons proposed for their residual refractive error.

Tecnis Toric IOL is an effective means of astigmatism correction in cataract patients. Thoughts on improving outcomes will be presented.
