Performance Comparison of the 25 Gauge 20,000cpm HYPERVIT Dual Blade vs. 10,000cpm ULTRAVIT Vitrectomy Cutter

This prospective randomised controlled trial will be conducted to investigate that increasing the vitrectomy cutting rate from 10,000 cut/min to 20,000 cut/min will result more efficiency and shorter core vitrectomy time, and it is equally safe as compared to the current 10,000 cut/min. We plan to target the patients undergoing for vitrectomy for common vitreoretinal pathology. Our plan is to conduct a randomised study with 2 arms, one with the higher cutting rate (20,000 cut/min) versus a second arm using the existing system 10,000 cuts/min.
