Background: Cataract surgery is almost exclusively performed under local anesthesia. Patients admitted for cataract surgery under local anesthesia by peribulbar injection have a more fear of pain rather than surgery itself. An essential prerequisite of successful pain management is adequate assessment of pain by using validated tools which are appropriate to the population or individual.

Aims: The objective of the study was to find out the threshold of pain associated with the peribulbar injection as local anesthesia for cataract surgery.

Materials & Methods: The present cross–sectional study involved 120 patients who underwent elective cataract surgery were administered a peribulbar block. Before injection all patients were briefed about the procedure, the degree of pain that they may experience & were asked to grade the pain of peribulbar anesthetic injection, using a Visual Analogue Scale (VAS).

Results: Total of 120 patients were participated in the study. Maximum patients i.e. 65% were in age group of ≥61 years. Males (57.5%) outnumbered females in the present study. Regarding degree of pain 9.2% patients didn’t felt any pain while 81.7% felt just needle prick lead to heaviness or mild pain. Only small percentage of patients i.e. 9.1% had injection associated moderate to severe pain. Other complications included chemosis in 4.2%, subconjunctival haemorrhage in 1.7% cases that didn’t hinder surgery. No other adverse local reaction or systemic complications were observed.

Conclusion: Focus of the study was on the degree of pain associated with peribulbar injection for cataract surgery & it has been concluded that the peribulbar anesthesia for cataract surgery is safe and highly effective with much less pain than actually patient have in their mind
