Topical anaesthesia with oxybuprocaine versus sub-Tenon’s infiltration with 2% lignocaine for small incision cataract surgery

AIMS To determine whether topical anaesthesia in small incision self-sealing phacoemulsification cataract surgery provides comparable anaesthesia to sub-Tenon’s infiltration. METHODS Thirty five patients undergoing small incision self-sealing phacoemulsification cataract surgery were allocated rando...

Description
Summary:AIMS To determine whether topical anaesthesia in small incision self-sealing phacoemulsification cataract surgery provides comparable anaesthesia to sub-Tenon’s infiltration. METHODS Thirty five patients undergoing small incision self-sealing phacoemulsification cataract surgery were allocated randomly to receive topical anaesthesia with 0.4% oxybuprocaine or sub-Tenon’s infiltration with 2% lignocaine. Pain experienced during the operation was assessed by asking the patient to score on a visual analogue graphic pain score chart. RESULTS The median pain score for the topical group (3) was significantly higher than that of the sub-Tenon’s group (0) (p = 0.004). CONCLUSION Sub-Tenon’s infiltration is superior to topical anaesthesia in ensuring patient comfort during small incision scleral tunnel self-sealing phacoemulsification cataract surgery.
