Purpose: To compare the influences on the corneal endothelium and surgically induced astigmatism following cataract surgery performed with Sovereign¨Þ and Infiniti¨Þ using the longitudinal phacoemulsification through the clear corneal incision.
Methods: Patients were operated on with the Sovereign¨Þ (n=46) and Infiniti¨Þ (n=45) programmed with the same parameters. Corneal thickness, endothelial cell count, effective phaco time and average phaco power were measured. Surgically induced astigmatism was calculated by keratometric readings.
Results: The change in corneal thickness at 1 day and endothelial cell count at 1 month postoperatively was significantly lower in the Infiniti¨Þ group. However, there were no significant differences in the change in corneal thickness and endothelial cell count at 2 months postoperatively. Surgically induced astigmatism in the 2 groups was consistently similar. Effective phaco time and average phaco power were lower in the Sovereign¨Þ group.
Conclusions: Using the longitudinal phacoemulsification, early postoperative change of corneal endothelium was lower in the Infiniti¨Þ group. However, the efficacy of phacoemulsification in the Sovereign¨Þ group was superior to the Infiniti¨Þ group.
