Design outcomes

Primary

Measure	Time frame
During this study, patient data will be collected and analyzed by means of intraoperative documentation. On the one hand, a well-founded statement about the quality of the incisions, the surgically induced astigmatism and the optimal or minimal limbal distance of the incisions during femto-cataract surgery will be made. On the other hand, incision patterns as well as the time of phacoemulsification will be analyzed in comparison to conventional cataract surgery.	—
