Abstract Details

Purpose:

To compare the safety of different settings of phacoemulsification by studying the changes in corneal thickness endothelium and central macular thickness.

Setting:

Tertiary care eye hospital of eastern India

Methods:

In this prospective randomized control trial 285 consecutive cases of phacoemulsification where randomly distributed into three different intraoperative settings. Group 1: IOP 20mmHg; aspiration 60 vacuum 700+ mmMg. Group 2: IOP 20mmHg; aspiration 26 vacuum 700+ mmMg. Group 3: IOP 46mmHg; aspiration 26 vacuum 650 mmMg. The following data were analyzed-  central corneal thickness, endothelial cell density and central macular thickness.

Results:

Post operative visual acuity, rate of PCR, intraocular pressure were not different in the three groups (p>0.05). Their was no difference in mean central corneal thickness and central macular thickness in the three groups (p>0.05). Mean endothelial cell density was significantly preserved in group 1 (p<0.05)

Conclusions:

Dissociative settings using low intraoperative pressure with high aspiration vacuum is an efficacious and safe way of phacoemulsification with additional advantage of preservation of endothelial cell density.
