A new cataract removal system with innovative fluidics has been developed. This study seeks to explore the possibilities afforded by the safe use of high vacuums with incisions of 2.2 and 2.0mm, while maintaining superior anterior chamber stability.

Access has been given to a pre-release version of this new cataract removal system. Phaco power parameters and fluidics parameters apart from vacuum are constant throughout the study. Each nucleus acts as its own control because a central trench is sculpted and each hemi-nucleus is removed with either high (600 mmHg) or low (350 mmHg) vacuum. Phaco power (CDE), estimated BSS used and procedure time for each hemi-nucleus are compared. An assessment of AC stability is made subjectively from the surgical video
Analysis of the surgical video confirms very good anterior chamber stability with the higher vacuum, even with 2.0 mm incisions. Preliminary results show a favourable profile of parameters measured with the higher vacuum setting (600 mmHg).
Early results with this new cataract system with innovative fluidics show that the use of high vacuums is safe, even with 2.0 mm incisions. There is an unprecedented stability of the anterior chamber even with such high settings, and therefore safe and efficient removal of cataract is possible.
