Study protocol
LENS
Surgical training was done individually in a wet lab center in São Paulo, Salvador, and Recife (Brazil). Both groups had a training module explaining the technique before performing the procedure. The procedure was performed using a model suitable for training of intraocular lens fixation SimulEYE® (INSEYET, WESTLAKE VILLAGE, CA, USA). The NGENUITY® 3D Visualization System (Alcon, Fort Worth, TX, USA) was used to train all participants and was used for all procedures. The system videos were captured through a capture card (Cam Link 4K –Elgato), and the procedure videos were recorded without audio for analysis by the masked graders. In the face-to-face training group, the mentor was in the same room as the trainee during the whole procedure, directly explaining the steps of the surgery. In the telementoring group, the images captured on a local computer were sent via control protocol/internet protocol (TCP/IP) transmission to a second computer located in another room. The images were transmitted through a videoconferencing platform (Zoom Inc., San Jose, California, USA) so that the mentor could follow the procedure in real-time. For communication between the surgeon in training and the mentor, another camera was used that captured the audio and images of the surgeon’s face (
