Background: Chalazion is a type of meibomian cyst. Lidocaine 2% local anesthetic injection is used for incision and curettage of chalazion. Lidocaine gel 2% is also being used now a days in chalazion surgery. Aim: To compare the efficacy of lidocaine 2% gel with lidocaine 2% injection in chalazion surgery evaluated in terms of mean pain score Methods: The study was cross sectional study and conducted in Department of ophthalmology Pakistan Institute of Medical Sciences Islamabad. The study duration was 8 months (November 2012 to July 2013). Sample size of 120 patients was achieved. A simple random sampling method was used for selection of patients. Patients were randomly allocated into two groups using lottery method. Ethical approval was taken from ethical review board of PIMS. . Data was collected through pre tested structured questionnaire. Results: Out of all 120 patients 60 patients were treated with lidocaine 2% gel and 60 patients were treated with lidocaine 2% injection. Out of all 120 patients there were 40 (66.7%) males and 20 (33.3%) females in lidocaine 2% gel group while in lidocaine 2% injection group there were 35 (58.3%) male and 25(41.7%) females. The mean pain in 2% lidocaine gel is 3.68 with 0.725 SD (p=0.017) while in 2% lidocaine injection group is 4.05 with 0.928 SD (p=0.017), so mean pain found to be higher in lidocaine 2% injection(95% CI). Conclusion: We conclude that 2% lidocaine gel is very effective in chalazion surgery especially in lowering the pain due to anesthetic administration.
