The Impact of Physiologic Cataract Surgery on Patient Comfort and Medication Usage
Matthew Rauen
Summary
The study will pertain to investigating the impact of high vs low IOP on the intraoperative experience and comfort for the patient and surgeon. Our hypothesis is that operating at a more physiological IOP using Unity VCS/CS and Centurion with Active Sentry at a higher, or more traditional IOP will result in significantly less discomfort/pain as assessed by the decreased need for rescue medication and lower VAS scores.
Description
Objective/ Unmet Medical Need: To investigate the impact of Unity VCS/CS with Intelligent Fluidics at a low IOP setting and Centurion with Active Sentry at a traditionally high IOP setting on the intraoperative experience for the patient and surgeon. Limited research on phacoemulsification at near physiological IOP and its impact on patient discomfort/pain using the Unity VCS/CS system. Design: Prospective, single-surgeon, eyes undergoing phacoemulsification will be randomized to high (IOP 65mmHg) or low (IOP 25mmHg) IOP, contralateral eye will receive other treatment.
