CATARACT, SEPARATION
Surgery was standardised with 23- or 25-gauge transconjunctival pars plana vitrectomy with posterior hyaloid face separation, if not pre-existing. All phakic patients underwent combined cataract surgery. After core and peripheral vitrectomy, ILM staining was performed with heavy brilliant blue G (BBG) 0.025% for 30-s contact time. All surgeons used pinch peeling as their preferred ILM peeling initiation technique. After the air-fluid exchange, 16% C2F6 was used as tamponade, and patients were instructed to position face-down for 3 days then non supine for 7 days. All surgeries were recorded.
