Participant flow

Recruitment details

Preoperatively, subjects were examined to ensure they met the inclusion/exclusion criteria. Patients were \>49 years of age, of any race and either gender. Patients had operable cataracts in at least one eye and were able to provide informed consent

Pre-assignment details

As access to Ophthalmic Viscosurgical Devices (OVDs) was limited, patients received whichever OVD was in stock at the time of surgery. 51 patients had a different OVD used in each eye. As a result, their demographic data is included in 2 OVD groups, resulting in a total of 224 patients (when group totals are added).
