Clinical Performance and Surgeon Acceptability of a New Dual Mode Phacoemulsification System

PURPOSE: The purpose of this first in-human study was to evaluate the overall clinical performance of the VERITAS™ Vision System in patients scheduled to undergo cataract extraction and to confirm overall surgeon acceptability. PATIENTS AND METHODS: This prospective, open-label multinational study included adults with cataracts scheduled for planned cataract extraction and posterior chamber IOL implantation. Standard small-incision phacoemulsification cataract surgery with the VERITAS Vision System was conducted. Surgeons completed a questionnaire regarding their clinical experience with the VERITAS Vision System for each patient following surgery and 1-day postoperative. Corneal clarity and adverse events (AEs) were assessed. Surgeon acceptability was scored on a 5-point scale, with acceptability considered favorable for scores of 4 and 5. RESULTS: A total of 115 eyes (79 patients) were treated. The El Salvador site treated 41 patients (58 eyes), and the US site treated 38 patients (57 eyes). Overall, surgeons were satisfied with the clinical performance regardless of the cataract grade. The satisfaction with anterior chamber stability, post-occlusion surge, followability, holdability, cutting efficiency, usability, and overall satisfaction with the VERITAS Vision System was clinically favorable in ≥99% of cases. Overall satisfaction with the swivel handpiece, foot pedal, and enhanced ergonomics were clinically favorable in ≥97% of cases regardless of the cataract grade. Satisfaction with corneal clarity at same-day postoperative and 1-day postoperative, and 1-day overall clinical results of surgery with the VERITAS Vision System were clinically favorable in ≥94% of cases regardless of cataract grade. CONCLUSION: The new dual-mode phacoemulsification system with dual-durometer tubing, gas forced infusion, new swivel handpiece, and ergonomics improvements resulted in a high rate of user satisfaction with clinical performance and ergonomics. The VERITAS Vision System is safe and effective when used as indicated.
