Venturi and Peristaltic Based Phacoemulsification in Femtosecond Laser Cataract Surgery

Completed

Conditions studied: Cataract Senile

In brief

This study will compare two methods of vacuum (peristaltic or venturi) commonly used during the removal of a femtosecond treated cataract. The investigators will observe which method uses less energy, is gentler on the eye, reduces corneal swelling and if the vision recovers faster with one method compared to the other.
