Naik MP, et al. - In this prospective, randomized, comparative observational study, researchers compared anterior chamber depth and postoperative visual outcome in patients undergoing phacoemulsification under topical vs peribulbar anesthesia. In contrast to the pre-op values, inter-group comparisons of postoperative change in ACD at 1-week post-op and 6-week post-op were statistically significant. Post-phacoemulsification, the ACD is more after peribulbar anesthesia than to topical anesthesia. Post-op refractive result is higher when using topical anesthesia.
