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.
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.

Charts from up to 200 myopic post-refractive patients who have received PanOptix will be reviewed at at least two Vance Thompson Vision sites (Fargo, ND and Sioux Falls, SD). All patients will have had ORA used during the cataract surgery.
