There is a wide range of techniques for local anaesthesia for cataract surgery including peribulbar, retrobulbar, sub-tenon and subconjunctival.
While topical and intracameral anaesthesia are becoming more popular anaesthetic modalities. Patients receiving topical bupicaine 0.5% with unpreserved intracameral lidocaine 1% during cataract surgery demonstrated a reduction in intraoperative analgesic requirements. Objective:
The objective of the study is to compare pain in patients with topical anaesthesia alone versus topical anaesthesia with intracameral lidocaine for phacoemulsification. Place of Study and Duration:
The study conducted at Department of Ophthalmology, Services Institute of Medical Sciences and Services Hospital, Lahore from january2018 to March 2019. Material and Methods:
It was a randomized controlled trial conducted at Department of Ophthalmology, Services Institute of Medical Sciences and Services Hospital, Lahore. The pain score in each patient was measured using Visual Analog Scale during the surgery. No pain 0-3 Pain 4-10 Results:
One hundred and twenty patients divided into two equal groups A and B, 60 patients of group A were operated with topical anaesthesia alone and other 60 of group B operated under topical anaesthesia along with intracameral Lidocain. Out of 120 patients 60 patients of group A have mean age of 54.55 and Standard Deviation 8.75 and 60 patients of group B gave mean age of 56.00 and Standard Deviation 9.01 Table-1. As regard to Gender of patients, out of 120 patients 61 (50.8%) were male and 59 (49.2%) were female Tale 2. Similarly in group B were having mean pain score of 2.07 and Standard Deviation 1.00 Table-3. Similarly as regard to the pain out of 120 patients 110 (91.7%) were have no pain and 10 (6.3%) patients were have pain Table-4. According to the groups, out of 60 patients in the group A (operated with topical anaesthesia alone) 52 patients were have no pain and 8 were have pain Table-5. Similarly in group B (operated under topical anaesthesia along with intracameral Lidocain) out of 60 patients 58 were have no pain and 2 patients were have pain Table-5, the resulted P value is P=.041. Conclusion:
There is significant reduction in pain score in patients operated under topical anaesthesia with intracameral lidocaine for phacoemulsification as compared to topical anaesthesia alone.
