Study	Reason for exclusion
Camesasca 2007	Endophthalmitis was not an outcome of the study: 2 different postcataract surgery antibiotic/steroid therapeutic combinations were compared in an intra‐individual randomized controlled trial; 142 participants (284 eyes) completed the 15‐day study; the study outcomes were efficacy of treatment, frequency of complications, and participant satisfaction.
Carron 2013	Endophthalmitis was not an outcome of the study: topical ciprofloxacin 0.3% prior to cataract surgery was compared with no antibiotics in a randomized controlled trial; 46 participants completed the 1‐day study; the study outcomes were the presence of bacteria in cultures taken the day prior to surgery, the morning of surgery, immediately before surgery, and at the end of surgery.
Cetinkaya 2015	Not a randomized controlled trial: intracameral moxifloxacin was administered following standard cataract surgery in some eyes, but not others; all participants received topical moxifloxacin for 1 week after surgery; data were reviewed retrospectively and participants with intraoperative complications were excluded from analyses; the study outcomes were postoperative best‐corrected visual acuity, anterior chamber cell and flare, intraocular pressure, and corneal edema.
Kolker 1967	Not a randomized controlled trial: subconjunctival injections of antibiotics were administered following intraocular surgical procedures (including cataract, glaucoma, corneal transplant, pupillary membrane needling, etc.) to alternate participants during the first phase of the study and to all participants subsequently; rates for postoperative endophthalmitis were not reported separately for people with cataract who did not receive antibiotics in the first phase of the study.
Li 2015	Not a randomized controlled trial: topical neomycin/polymyxin‐B was administered either 1 day or 1 hour prior to cataract surgery; the authors reported the study as a prospective comparative case series; the study outcomes were the presence of bacteria in cultures taken prior to the application of povidone‐iodine before surgery, after the application of povidone‐iodine before surgery, and at the end of surgery.
Maloof 2004	Not a randomized controlled trial: letter reporting changes made by a hospital following an increased rate of endophthalmitis; changes included reorganizing the layout of the operating theater and administering postoperative intracameral vancomycin.
Paganelli 2009	Endophthalmitis was not an outcome of the study: an intraoperative injection of triamcinolone and ciprofloxacin in a controlled‐release system (DuoCat) was compared with prednisolone and ciprofloxacin eye drops after cataract surgery in a randomized controlled trial; 135 participants completed the 4‐week study; the study outcomes were postoperative anterior chamber cell and flare, intraocular pressure, lack of anti‐inflammatory response, and presence of infection.
Peyman 1977	Not a randomized controlled trial: South Indian eye camps were sequentially divided into 3 groups of treatment regimens: group 1: no prophylactic intracameral gentamicin was used, but oral and topical chloramphenicol was given to all participants; group 2: female participants received prophylactic intracameral gentamicin, but no chloramphenicol and male participants received oral and topical chloramphenicol, but no prophylactic intracameral gentamicin; group 3: all participants received prophylactic intracameral gentamicin, but no chloramphenicol or any other antibiotic was given.
Pérez‐Canales 2015	Not a randomized controlled trial: intracameral injections of vancomycin versus cefuroxime were administered at the end of cataract surgery; the authors reported the study as a prospective comparative case series; the study outcomes were postoperative uncorrected and corrected distance visual acuity, refraction, anterior chamber cell and flare, intraocular pressure, endothelial specular microscopy, and corneal edema and thickness.
