Abstract

To evaluate whether the addition of intracameral lidocaine to topical anaesthesia during cataract surgery leads to a decrease in the administration of intraoperative midazolam and fentanyl. Retrospective case-control study. The eyes of 124 patients undergoing phacoemulsification were included in the study, with 62 in the intracameral group and 62 in the control group. A single-centre, retrospective chart review of cases between April and October 2007 in which patients had undergone small-incision phacoemulsification with foldable intraocular lens insertion and received preoperatively either topical tetracaine 0.5% with unpreserved intracameral lidocaine 1% (intracameral group) or topical tetracaine 0.5% alone (control group). Intraoperatively, midazolam and fentanyl were administered as needed based on pain and anxiety. A total of 124 eyes (124 patients) were included. There was no statistically significant difference between the mean intraoperative midazolam doses given for the 2 groups (p = 0.08). The mean intraoperative dose of fentanyl was lower in the intracameral than in the control group (p < 0.0001). A comparison of intraoperative fentanyl requirements between groups using a multivariate regression analysis for age, gen...Continue Reading
