Abstract Details


To compare and determine patients and surgeons comfort and satisfaction in phacoemulsification under topical anesthesia with proparacaine hydrochloride 0.5% versus subconjunctival infiltration with 2% lidocaine


Regional Institute of Medical Sciences, Imphal, India.


26 patients of cataract divided into two groups, A and B each containing 13 patients were included in the study. phacoemulsification was performed on group A under topical anesthesia with proparacaine hydrochloride 0.5% and on group B under topical anesthesia along with subconjunctival infiltration of 2% lidocaine. un co-operative patients, those with previous ocular trauma and corneal opacities were excluded from the study. All patients in both groups were operated by the same surgeon. the surgeon and patient satisfaction score was entered in a standardized proforma.


10 patients (76%) in group A felt no pain while 3 patients (23%) felt pain upto the extent that 0.5 cc of 2% lidocaine was needed to infiltrate at the phaco port site. thereafter the procedure was competed comfortably and pain free. Mean phacoemulsification time was 2.5 minutes and mean operation time was 30 minutes. In group B, the patients were operated after infiltration of 0.5 cc 2% lidocaine injection. All the patients were operated pain free. The mean phacoemulsification time was 2.2 minutes and the mean operation time was 30 minutes


The subconjunctival infiltration of 2% lidocaine injection with topical anesthesia is superior to topical anesthesia with prparacaine hydrochloride alone during phacoemulsification ensuring patients and surgeons comfort. None of the patients in any group showed the complication as sometimes seen in periocular and retrobulbar anesthesia FINANCIAL DISCLOSURE?: No
