A study of effect of intracameral use of preservative-free lignocaine (1%) for pupillary dilatation during phacoemulsification surgery

Abstract

Aim: The aim of the study was to assess the effect of intracameral preservative-free lignocaine (1%) on the dilatation of pupil while doing phacoemulsification surgery. Materials and Methods: A prospective study carried out on 21 patients in a tertiary care hospital. The pupil diameter was measured just before instilling intracameral preservative-free lignocaine, after 1 min and 5 min, respectively. Any mydriatic was not used either before or during the surgery. Effects were compared between male and female patients and between light- and dark-colored irides patients. Results: The diameter of pupil after instillation of intracameral lignocaine was significantly higher. The effect was more pronounced in light-colored irides. There was no difference in the pupillary diameter between both the sexes. Conclusion: Intracameral preservative-free 1% lignocaine has a fast and effective mydriatic property and with more studies, can be used as a safe alternative to topical and intracameral mydriatic while phacoemulsification.
