Abstract

AIM:

To compare the efficacy and safety of 0.5% intracameral lignocaine to 1% intracameral lignocaine prior to phacotrabeculectomy.

STUDY DESIGN:

Prospective, comparative, observational, and interventional study.

SETTING:

Tertiary eye care center in central India.

MATERIALS AND METHODS:

This study was comprised of 79 patients (79 eyes) with primary open angle glaucoma scheduled for phacotrabeculectomy. Patients were assigned to 1 of 2 Groups receiving proparacaine 0.5% eye drops and 1% intracameral lignocaine just prior to phacotrabeculectomy (Group 1, n = 39) and 0.5% intracameral lignocaine after completion of phacoemulsification just prior to trabeculectomy (Group 2, n = 40). The visual analogue scale was used to record intraoperative and postoperative pain. Patient comfort, intraoperative painful sensations perceived by the patient, supplemental anesthesia, complications, and surgeon discomfort were noted. An anesthetist also noted the vital parameters and the requirement for intravenous medications.

RESULTS:

There was no significant difference in the intraoperative pain score (P = 0.0733) or supplemental anesthesia (P = 0.372) between Groups. Postoperative pain score was statistically significant in Group 2 (P < 0.0001). The overall operating conditions in both Groups were comparable (P = 0.7389). A greater number of patients in Group 2 (88.57%) preferred the same anesthetic technique for combined surgery in the fellow eye. There was no difference in inadvertent eye movements and lid squeezing between Groups and they did not interfere with surgery.

CONCLUSION:

Topical anesthetic drops supplemented with 0.5% intracameral lignocaine before performing trabeculectomy is as effective as 1% intracameral lignocaine given at the beginning of phacotrabeculectomy for primary open angle glaucoma.
