Abstract |
PURPOSE To compare the influences on the corneal endothelium and surgically induced astigmatism following cataract surgery performed with Sovereign(R) and Infiniti(R) using the longitudinal phacoemulsification through the clear corneal incision. METHODS: Patients were operated on with the Sovereign(R) (n=46) and Infiniti(R) (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(R) 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(R) group. CONCLUSIONS: Using the longitudinal phacoemulsification, early postoperative change of corneal endothelium was lower in the Infiniti(R) group. However, the efficacy of phacoemulsification in the Sovereign(R) group was superior to the Infiniti(R) group. |
