Effect of intraocular acetylcholine and carbachol on the corneal endothelium. In vivo comparative study

Abstract

The purpose of this study is to evaluate differences in corneal endothelial cell loss after intraocular use of two different miotics in subjects who have undergone extracapsular cataract extraction with posterior chamber intraocular lens implantation. The patients were divided into two groups: the first received 1 ml of 1% acetylcholine chloride and the second 0.5 ml of 0.01% carbachol as intraocular miotics. The endothelial count was done preoperatively and then 1 month after cataract extraction. There were no statistically significant differences in the mean cell loss between both groups. The authors believe that both miotics could be used in cataract surgery.
