Description of intervention(s) / exposure
Patients will be asked to grade pain experienced during both first and second eye cataract surgery under topical anesthesia, using a Visual Analog Scale. Difference in pain perception during first and second eye surgery will then be evaluated. Partecipants will be recruited over a period of 3 years, in order to reach a sample size of 60 patients for statistical evaluation. Allowing for possible drop-outs due to intraoperative events causing differences in surgical technique, at least 70 elegible patients will be recruited for the study
