Objectives
Narrative objectives1
In recent years, cataract surgery has made remarkable progress, and expectations of patients have been growing for the surgery. The patients especially have higher expectations for Premium IOLs in terms of its property and those need higher accuracy of the preoperative examination and the IOL power calculation.
ORA, an intraoperative wavefront aberrometry, enables surgeons to measure the refraction in the aphakic phase and determine the IOL power intraoperatively, and ORA has been reported that it has the same or higher accuracy of predicted postoperative refraction as the preoperative IOL power formulas. On the other hand, PanOptix is the first approved trifocal intraocular lens in Japan, and it is reported that PanOptix shows good visual performance and satisfaction. Although further improvements in accuracy and satisfaction can be expected by using ORA, there is few reports to have assessed the predictive accuracy of ORA with PanOptix.
Not only spherical equivalent refractive errors but also residual astigmatism highly influence on the postoperative satisfactions. We have experienced some cases, in which the preoperative examination indicated the adaption of non-Toric IOL but the residual astigmatism remained after the surgery, and Toric IOL should have been inserted. Thus, it is desirable to be able to choose Toric or non-Toric and determine the cylindrical power of Toric IOL before the IOL insertion. Therefore, we decided to conduct a retrospective study to compare ORA with the preoperative IOL power calculation formulas in the predictive accuracy for PanOptix and PanOptix Toric, and also to investigate correlation between the postoperative residual astigmatism and each factor.

The predictive refractive accuracy of ORA for PanOptix (non-Toric) and PanOptix Toric will be evaluated in comparison to preoperative IOL power calculations. In addition, factors associated with postoperative residual astigmatism will be investigated.
