Abstract

Aim: To compare subtenon’s block with peribulbar block with respect to complications encountered.
Materials and Methods: A prospective, comparative time bound study was conducted including a total
of 140 patients who were randomized into 2 groups; 70 patients each in PB Group (peribulbar block)
and 70 in ST Group (subtenon’s block) who were selected for manual small incision cataract surgery.
Any complications during administration of anaesthetic, limitation of ocular movements and onset of
anaesthesia was assessed before starting the surgery and documented.
Results: Most of the patients 92(65.7%) were between 50 to 60 years age. 58 patients in Peribulbar group
experienced moderate pain at the time of block while only 18 patients experienced it in Subtenon’s group.
Subconjunctival haemorrhage was seen limited to the site of anaesthetic administration in 52 patients in
subtenon’s group. The onset of akinesia with subtenon’s block was (3min+/ 1.5min) compared to peribulbar
block (7min+/2min).
Conclusion: Subtenon’s anaesthesia is safe and effective in manual small incision cataract surgery.

Keywords: Anaesthesia, Peribulbar, Subtenon’s.
