    Abstract:
    PURPOSE: To report the incidence, clinical settings, and visual acuity outcomes of acute-onset endophthalmitis after cataract surgery. DESIGN: Retrospective, observational case series. METHODS: Annual cataract surgery statistics were determined by review of electronic surgical records. The clinical and microbiologic records were reviewed of all patients with clinically diagnosed endophthalmitis within 6 weeks after cataract surgery at a single university-affiliated hospital between January 2000 and November 2004. main outcome measures: Operative technique, intraoperative complications, and visual acuity. RESULTS: The incidence of acute-onset endophthalmitis after cataract surgery was 0.04% (7/15,920) for cataract surgeries of all methods, 0.05% (6/11,462) for cataract surgery by clear cornea phacoemulsification, and 0.02% (1/4,458) for cataract surgery by methods other than clear cornea phacoemulsification (P = .681, Fisher's exact test). Six of seven (86%) cases occurred in the right eye, and all cases were performed by right-handed surgeons through temporal incisions. Five of seven (71%) patients had relative immune compromise. Four of seven (57%) patients had an intraoperative complication: vitreous loss in three patients and iris prolapse in one patient. Two patients had topical placement of lidocaine 2% gel before povidone-iodine preparation. The visual acuity at final follow up was 20/25 or better in four patients and count fingers or worse in three patients. CONCLUSIONS: The incidence of acute-onset endophthalmitis after temporal clear cornea incision phacoemulsification is low (0.05%). Potential risk factors for endophthalmitis may include intraoperative complications, relative immune compromise, application of lidocaine 2% gel before povidone-iodine preparation, and inferior incision location.
