Abstract

We evaluate central endothelial cell loss(ECL) following phacoemulsification through a temporal sclera tunnel incision and temporal clear corneal incision. Seventy two eyes that had phacoemulsification surgery were divided into two groups. In group 1(n=41), a foldable silicone intraocular lens(IOL). was implanted through a 3.2mm sutureless clear corneal incision. In group 2(n-31), a 5.5mm sutureless scleral tunnel incision. Cell density of the corneal endothelium in all eyes was recorded preoperatively and 2 months postoperatively. and the percentage of endothelial cell loss was determinded. Percentage of endothelial cell loss were 8.37+/-7.5% in group 1, 6.61+/-7.1% in group 2. Phacoemulsification with 5.5mm scleral tunnel incisions produced slightlyless ECL than Phacoemulsification with 3.2mm clear corneal incisions. No statistically significant difference was observed among these two groups.
