Purpose : The aim of the study was to identify the incidence of SubTenon's related complications during cataract surgery.

Methods : Retrospective review of the available electronic patient's records of all the patients that underwent cataract surgery at Harrogate District National Health System Foundation Trust between June 2007 and September 2017 was performed. Anaesthetic complications, peri-operative and post-operative complications were recorded as well as the anesthetist grade.

Results :

Of the 11,450 cataract operations studied, 291 had anaesthesia related complications (2,54%). Subconjunctival haemorrhage was reported in 154 patients (1.34%), 94 patients (0.82%) had conjunctival chemosis, 30 patients (0.26%) had uncontrolled eye movement, 8 patients (0.07% ) experienced pain/discomfort, 2 patients had eyelid bruising (0.02%), 3 patients (0.03%) had intraoperative suprachoroidal haemorrhage. Multivariate logistic regression performed showed that the complications were random and did not correlate with the grade of the anaesthetist.

Conclusions : The incidence of SubTenon's anaesthesia related complications seems to be low rendering this type of anesthesia an effective and safe anaesthetic option for cataract surgery.
