The carbon footprint of cataract surgery in a French University Hospital.

Purpose: To assess the carbon footprint of cataract surgery in a French university hospital.

Setting: Operating room of Cochin University Hospital, Paris, France.

Design: Single-center component analysis.

Preoperative imaging optimized for epiretinal membrane surgery.

Background: To compare imaging modalities for visualizing primary epiretinal membrane (ERM) with each other and with intraoperative digital images (IDI) after blue staining.

Methods: The records of consecutive patients operated for primary ERM over a 12-month period were retrospectively reviewed. Preoperative imaging included color fundus photography (CFP), En Face spectral-domain optical coherence tomography (OCT), 45° infrared- (IR) and blue-reflectance (BR) scanning laser ophthalmoscopy.
