BACKGROUND AND OBJECTIVE: The purpose of this randomized, single-masked clinical trial is to explore whether cefazolin mixed with 2% lidocaine can reduce pain.
PATIENTS AND METHODS: Patients naïve to ophthalmic surgery were randomized to subconjunctival injection of either a 0.5 mL cefazolin-balanced salt solution (0.3 mL cefazolin and 0.2 mL balanced salt solution) or 0.5 mL cefazolin-lidocaine solution (0.3 mL cefazolin and 0.2 mL 2% lidocaine) during retinal surgery with a retrobulbar block. Pain scores were obtained at the start of surgery, middle of surgery, before and after cefazolin administration, and postoperatively.
RESULTS: A total of 54 patients were recruited; 44.6% were male, and the mean age was 60.1 years ± 13.5 years. There were no statistically significant differences between the groups' operative characteristics or pain scores at each study time point.
CONCLUSION: In pars plana vitrectomy with or without phacoemulsification and intraocular lens insertion, subconjunctival cefazolin mixed with lidocaine conferred no added analgesic benefit. [Ophthalmic Surg Lasers Imaging Retina. 2017;48:881-886.].
