Study Comparing High-frequency Pulsed Vacuum Technology and Phacoemulsification for Cataract Surgery For Adults with Bilateral Cataracts

What this Trial Is About

Researchers are evaluating a new technology called high-frequency pulsed vacuum for cataract surgery, comparing it to the commonly used phacoemulsification technique. Cataracts cause clouding of the eyes lens, mainly due to aging, and surgery is the primary treatment. This study aims to show the benefits of the pulsed vacuum approach, especially for patients with at-risk corneas, by conducting a randomized, comparative, crossover trial. The study compares two surgical methods one uses high-frequency pulsed vacuum technology to break up and remove the cataract in a less invasive way, while the other uses phacoemulsification, which employs ultrasound to fragment the lens. Participants will have both eyes operated on, with the order of techniques randomized between eyes. The pulsed vacuum method interrupts vacuum pulses to safely dissect cataract material while maintaining eye stability and reducing tissue damage. During the study, participants will be assessed before and after each surgery, including checks of visual acuity, inflammation, complications, and endothelial cell count using specular microscopy at about 30 days post-surgery. The surgical time, patient comfort, satisfaction of healthcare teams, and adverse events will also be monitored. This detailed follow-up aims to measure safety and recovery outcomes over the course of the trial.
