Abstract Details

Purpose:

Evaluation of the safety , efficacy and outcome of subtenon anaesthesia with peribulbar anaesthesia in Phacoemulsification cataract surgery.

Setting:

Chandraprabha Eye Hospital, Jorhat, Assam, India- 785001

Methods:

This was a prospective randomized controlled study with 500 eyes of 420 patients between july 2017 to December 2017 who underwent phacoemulsification surgery. All the patients were randomly divided into 2 groups. Group A underwent phacoemulsification with subtenon aneasthesia and group B underwent phacoemulsification with peribulbar aneathesia. Pain during administration of anaesthesia, during surgery and 4 h after surgery was graded on a visual analogue pain scale and compared for both the techniques. Sub-conjuntival haemorrhage, chemosis, akinesia after administration of anaesthesia and positive pressure during surgery were also compared. Patients were followed up for 6 weeks postoperatively.

Results:

All the patients were followed up for 6 weeks. In subtenon group 202 out of 250 patients(80.8%)did not experienced any pain during administration of aneasthesia. Meanwhile in peribulbar group only 48 out of 250 patients (19.2%) did not received any pain during administration. There was no significant difference in pain during and 4 h after surgery. Subtenon group had slightly more sub-conjunctival haemorrhage. About 178 (71.2%) patients of the peribulbar group had absolute akinesia during surgery as compared to none (0%) in sub-tenon group.There was 1 case globe perforation during peribulbar administration.

Conclusions:

Sub-tenon anaesthesia is safe and as effective as peribulbar anaesthesia and is more comfortable to the patient at the time of administration.
