The dataset consists of 50 videos of cataract surgeries performed in Brest University Hospital between January 22, 2015 and September 10, 2015. Reasons for surgery included age-related cataract, traumatic cataract and refractive errors. Patients were 61 years old on average (minimum: 23, maximum: 83, standard deviation: 10). There were 38 females and 12 males. Informed consent was obtained from all patients. Surgeries were performed by three surgeons: a renowned expert (48 surgeries), a one-year experienced surgeon (1 surgery) and an intern (1 surgery). Surgeries were performed under an OPMI Lumera T microscope (Carl Zeiss Meditec, Jena, Germany). Videos were recorded with a 180I camera (Toshiba, Tokyo, Japan) and a MediCap USB200 recorder (MediCapture, Plymouth Meeting, USA). The frame definition was 1920x1080 pixels and the frame rate was approximately 30 frames per second. Videos had a duration of 10 minutes and 56 s on average (minimum: 6 minutes 23 s, maximum: 40 minutes 34 s, standard deviation: 6 minutes 5 s). In total, more than nine hours of surgery have been video recorded.
