Clinical Trial Summary

To compare the prediction error of ORA vs formula for post-LASIK cataract patients when PanOptix IOL was implanted. Using post-operative outcomes to determine if preoperative IOL calculations, including Barrett TK, Barrett Universal II, Hill RBF, ASCRS post-refractive calculator, or intraoperative aberrometry is more accurate when the two methods disagree in patients who have had previous refractive surgery undergo cataract surgery.

Description:

The study will be non-interventional with data being collected prospectively and retrospectively between at least two surgical sites. All subjects will have previous LASIK and be at least 3 months post op PanOptix implantation. The study will enroll up to 200 patients and a statistical database will be created.
