ABSTRACT
Background: Cataract is a frequent surgical procedure performed worldwide. The study compared lidocaine 4% drops with 2% gel on surgeon抯 comfort, need for supplemental anaesthesia and duration of surgery in patients who underwent manual small incision cataract surgery.Methods: This was a Prospective, Comparison study conducted at a Single centre by multiple surgeons. Patients enrolled for surgeries were divided into Group A: Lidocaine 4% drops 1ml was instilled in the conjunctival sac 5 minutes before surgery and Group B: Lidocaine 2% gel 2ml was applied. Endpoints evaluated were surgeon抯 comfort, need for supplemental anesthesia and duration of surgery.Results: The mean duration of surgery for gel was 20�minutes as compared to 29�minutes with drops (p*- value<0.001). 26 (87%) patients in gel did not require any supplemental anesthesia as compared to 3 (10%) patients in drops. Peribulbar supplementation was required for 20 (67%) patients in drops as compared to 1 (3%) patient in gel (p*- value<0.001). 26 (87%) patients in gel were operated comfortably by the surgeon as compared to 2 (6%) patients in drops. Mild to Moderate discomfort was experienced by the surgeon in operating 27 (90%) patients in drops as compared to 3(10%) patients in gel (p*- value<0.001).Conclusions: The surgeons were more comfortable using gel with least requirement of supplemental anaesthesia and faster completion compared to drops.
ABSTRACT
Background: Cataract is globally acknowledged leading cause of blindness. This study was undertaken to compare the effects of Lidocaine 4% drops with 2% gel on intra operative and post-operative pain in patients who underwent manual small incision cataract surgery.Methods: It was a single Centre, one-surgeon, prospective, comparison study. Patients enrolled for surgeries were divided into Group A: Lidocaine 4% drops 1 ml was instilled in the conjunctival sac 5 minutes before surgery and Group B: Lidocaine 2% gel 2ml was applied. Endpoints evaluated were ocular pain of patient during and after surgery.Results: A total of 60 patients underwent MSICS, out of which 30 each received drops and gel. Mean intraoperative pain VAS score was 2.26±0.69 for gel group and 5.13±1.13 for drops group (p*<0.001) Mean post-operative pain VAS score was 0.26±0.69 in gel group and 1.13±1.13 in drops group (p*=0.002).Conclusions: Compared to drops, Lidocaine gel has reduced intraoperative and post-operative pain.
