Abstract

AIM: To study the effect of intracameral injection of preservative-free lignocaine to induce pupil dilatation, without using any preoperative dilating eyedrops or intraoperative mydriatics in patients with age-related cataract associated with type 2 diabetes mellitus.

DESIGN: This was a prospective, observational, and interventional case series conducted at a tertiary eyecare center in rural India.

MATERIALS AND METHODS: A total of 32 patients underwent phacoemulsification under topical anesthesia for visually significant cataract. Preoperative pupillary diameter was measured 3 days prior to surgical procedure under mydriatics (tropicamide 0.8%, phenylephrine hydrochloride 5%). Intraoperative pupillary dilatation was achieved by 1% intracameral lignocaine solution alone. Effective phacoemulsification time (EPT), total surgical time, and final pupillary diameter were recorded at the conclusion of surgery.

RESULTS: The average duration of diabetes was 11.2 (range 5-25) years. There was no difference in dilatation by preoperative pupil-dilating drops (5.2±0.5 mm, range 3-8.3 mm) and intracameral 1% lignocaine during the surgical procedure (

CONCLUSION: Intracameral lignocaine 1% provides sufficient mydriasis for the safe phacoemulsification of cataract in patients with type 2 diabetes of variable duration.

Keywords: intracameral lignocaine; intracameral mydriatic solution; phacoemulsification; topical anesthesia; type 2 diabetes
