Purpose: To assess and compare the corneal endothelial affection during phacoemulsification when using irrigating fluid of either balanced salt solution (BSS) or Ringer's lactate (RL) during the procedure of managing dense brunescent cataract in old age. Design: Randomized controlled clinical trial Methods: The study included fifty eyes of 45 patients of? 68 years. All patients had senile nuclear cataract of grade > IV undergoing phacoemulsification. They were equally divided into group A, where the surgery was performed using BSS infusion fluid, and group B using RL Observations made included specular microscopy to evaluate endothelial cell density (ECD) and endothelial cell size variability (CV), corneal pachymetry for central corneal thickness (CCT), and any other complications. Evaluation was done preoperatively and 1 week and 6-8 weeks postoperatively.
