Summary

The objective of this study is to evaluate uncorrected distance vision and quality of vision as measured by the McAlinden QoV questionnaire 3 months following the final lock-in treatment of the implanted RxSight Light Adjustable Lens (RxLAL) with the Light Delivery Device (LDD) in subjects with preoperative keratometric astigmatism. This is an exploratory study. No primary effectiveness endpoints will be defined.
