Abstract Details

Purpose:

To evaluate post-operative (21-35 day) mean refractive astigmatism outcomes and residual refractive astigmatism distribution after using intraoperative aberrometry during lens replacement procedures to guide cylinder power selection and axis of placement.

Setting:

Prospective, multicenter, masked evaluator study

Methods:

Subjects (n=84) were analyzed for this prospective, multicenter, masked evaluator study. Evaluators were masked to treatment and toric IOL type. Data related to mean pre- and post-operative refractive astigmatism were collected and analyzed. The distribution of post-operative residual refractive astigmatism was evaluated.

Results:

Mean pre- and post-operative refractive astigmatism were 1.72D ± 0.75 and 0.26D ± 0.31, respectively. Post-operative residual refractive astigmatism distribution was as follows: ≤0.25D, 69%; ≤0.50D, 89%; ≤0.75D, 94%; ≤1.00D, 99%.

Conclusions:

This descriptive study demonstrated that using intraoperative aberrometry reduced refractive astigmatism with 89% of those cases resulting in ≤0.50D and nearly all (99%) subjects to ≤1.00D with of residual refractive astigmatism.
