Participant gender:
All
Summary
The primary aim of the study is to compare the effectiveness of the intracameral application of Mydrane® (standardized combination of Tropicamide 0.02%, Phenylephrine 0.31% and Lidocaine 1%) with the preoperative topical application (Tropicamide 0.5% and Phenylephrine 10%). To evaluate the steadiness of the dilating effect on the pupil, the ratio of eyes without necessity for further pupil dilating procedures to perform the capsulorhexis is assessed.
