Purpose: The aim of this study was to compare the perioperative time and economic impact of a licensed intracameral anaesthetic/mydriatic combination (Mydrane) during routine cataract surgery.

Methods: A real-life, prospective, comparative study was performed in 3 clinical centres in France. Preoperative, surgical, and post-operative times were determined for two mydriasis strategies using conventional preoperative mydriatics/anaesthetics eye drops (control regimen) or Mydrane administered at time of surgery.
