To evaluate the efficacy of topical incisional site sub-conjunctival 2% and intracameral 1% lignocaine anesthesia in terms of pain, surgical complications, and visual outcome in manual small incision cataract surgery.
Data was prospectively collected for 48 cataract patients treated by a single surgeon at the National Eye Center in Dili, Timor-Leste. Patients received 0.3 ml sub-conjunctival 2% lignocaine and 0.2 ml intracameral 1% lignocaine as anesthesia and Modified Wong-Baker Faces Pain reading scale was used to measure pain score. Patients who had undergone surgery in the fellow eye under peri/retro bulbar or sub-tenon anesthesia were also asked about eye pain during previous procedure.
Of the 48 patients analyzed, 31 (64.6%) were male and 17 (35.4%) female. The average age of patients was 60.8 years (SD 12.9). Majority of the patients had no pain with a few reporting minor pain. Surgeon’s experience was favorable in terms of patient cooperation, ocular movement, and anterior chamber stability. Over 95% of cases resulted in vision 6/18 or better.
Topical anesthesia with sub-conjunctival 2% and intracameral 1% lignocaine for manual small incision cataract surgery shows to be promising in this population considering patient comfort, surgeon experience, potential hazards, and visual outcome.
