Surgical procedure
For all patients, standard phacoemulsification under topical anaesthesia (lidocaine 4%) was performed via a temporal 2.2 mm posterior limbal incision. The following eyedrops were administered 20 min before surgery: 1% tropicamide, 10% neosynephrine, nepafenac and moxifloxacin. Standard antisepsis of the ocular surface with 5% iodine povidone for 3 min and periocular skin with 10% iodine povidone for 5 min was performed immediately before draping the eyelids. At the time of surgery, all patients received intracameral cefuroxime (Aprocam, Théa Pharmaceuticals Limited, Newcastle-under-Lyme, UK) injection.
