Narrative Responses:

Purpose
To determine the accuracy of an intraoperative wavefront aberrometer by comparing predicted and measured residual refractive error for eyes that underwent routine cataract surgeries with toric intraocular lenses (IOL).

Methods
A retrospective study of 50 eyes that received a toric IOL utilizing the intraoperative wavefront aberrometer ORA System (WaveTec Vision) to select the lens power and to guide the final lens orientation. After the first postoperative month, a manifest refraction was obtained for spherical equivalent, cylinder, and axis. These outcomes were then compared with the ORA System’s predicted residual refractive error.

Results
Preliminary results demonstrate reliable outcomes, and final results will be tabulated prior to presentation.

Conclusion
The intraoperative wavefront aberrometer is a useful device for refining the selection of toric IOL power and guiding final lens orientation.
