Performance characteristics of a straight versus bent 25-gauge vitrector.

Background And Objective: During vitrectomy in phakic patients, lens damage can occur while shaving the peripheral vitreous. Modifying the vitrector with a slight bend can diminish this risk.

Materials And Methods: To assess whether the bent vitrector performs to standard, the cutting and aspiration functionality of a straight and bent cutter was tested on both the vitreous from an enucleated porcine eye and balanced salt solution.
