Systemic adverse events: a comparison between topical and peribulbar anaesthesia in cataract surgery.
OBJECTIVE
To evaluate the safety of topical anaesthesia (TA) versus peribulbar anaesthesia (PBA) in patients undergoing routine cataract surgery on the basis of systemic adverse events.


METHODS
In this retrospective study, a total of 2,020 consecutive cases of cataract surgery performed by one surgeon on 1,621 patients with PBA (n = 1,010; between 1998-1999) or TA (n = 1,010; between 1999-2001) were evaluated on the basis of intra-operative and early postoperative adverse events requiring medical intervention.


RESULTS
The rate of pre-existing risk factors in patients undergoing cataract surgery is high (97%). Complications are significantly less frequent in TA than in PBA in the intra-operative (p < 0.001) and postoperative (p = 0.022) courses. The incidence of intra-operative complications is higher in elderly patients (>or=65 years of age) than in younger patients (p < 0.001).


CONCLUSIONS
The results from the present study indicate that intra-operative complications are less likely in patients that receive TA, suggesting the use of TA for routine cataract surgery both in young patients and particularly in elderly patients when there are no contraindications in the individual case.
