The phacoemulsification performed equally well in a comparative study that also considered the different incision sizes.
Phacoemulsification systems are not all equal. They come with different components that can affect the outcomes.
Ninety eyes undergoing cataract surgery were included. Thirty eyes were treated with the Stellaris system with implantation of an Akreos MI IOL (Bausch + Lomb) through a 1.8-mm incision using longitudinal ultrasound and non-pressurized infusion; 30 eyes were treated with the Stellaris system with implantation of the Akreos MI IOL through a 1.8-mm incision with pressurized infusion; and 30 eyes were treated with the Infiniti system with implantation of an AcrySof IOL (Alcon) through a 2.2-mm incision, torsional ultrasound, and non-pressurized infusion.
