Pre-Operative Diclofenac Sodium Eye Drops Vs Intra-Operative Adrenaline Irrigation in Maintaining Mydriasis during Extracapsular Cataract Extraction

Abstract

Purpose: To compare the effectiveness of pre-operative diclofenac sodium eye
drops with per-operative intraocular irrigation with adrenaline 1:1,000,000 (one in
one million) solution in maintaining mydriasis during cataract surgery.
Material and Methods: It was a randomized control trial and was conducted in
the department of Ophthalmology, Khyber Teaching Hospital Peshawar from
September 2010 to March 2011. 210 patients with senile mature cataracts were
divided into two groups “A” and “B” with 105 patients in each group. Group “A”
received pre-operative diclofenac eye drops for 24 hours and group “B” received
per-operative irrigation with 1:1,000,000 of adrenaline solution. In all patients
pupillary size was measured after cortical matter removal during extracapsular
cataract extraction.
Results: The mean age of patients in group “A” was 59.87 ± 6.54 SD years and
in group “B” was 61.38 ± 6.30 SD. The mean pupillary size after cortical matter
removal in group “A” was 7.0667 mm ± 1.78 SD while that in group “B” was
8.3371mm ± 1.94SD. The difference between the two was statistically significant
after applying independent sample„t? test with p value of <0.000.
Conclusion: Per-operative irrigation of adrenaline 1:1,000,000 solution keeps
better pupillary size as compared to pre-operative diclofenac sodium for patients
undergoing extracapsular cataract extraction,
