What this trial studies

This study aims to compare the effectiveness and safety of femtosecond laser-assisted cataract surgery using the Active Sentry handpiece against standard phacoemulsification techniques. The femtosecond laser automates critical steps in the surgery, potentially reducing collateral damage and improving outcomes. The Active Sentry handpiece monitors intraocular pressure in real-time to enhance safety during the procedure. The study will evaluate differences in cumulative dissipated energy and corneal endothelial cell loss between these techniques.

Who should consider this trial

Good fit: Ideal candidates for this study are adults over 18 years old undergoing uncomplicated cataract surgery.

Not a fit: Patients with a history of ocular surgery or concomitant ocular diseases other than cataract may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to safer and more effective cataract surgery options for patients.

How similar studies have performed: Other studies have shown promising results with femtosecond laser-assisted techniques, indicating potential for success in this approach.
