Abstract
To design an improved self-stabilizing lens ring for 25-gauge vitrectomy. Device report. A lens ring was designed to be fixated to the globe using 25-gauge transconjunctival cannulas. This ring consists of a single plastic component with multiple concavities at the ring margin to fit 25-gauge cannulas. The ring can accommodate conventional standard and panoramic vitrectomy lenses. A lens ring has been designed for 25-gauge vitrectomy and to hold conventional contact lenses. Stability of the lens ring is achieved without the need for sutures and instead is achieved by the three point fixation provided by the existing 25-gauge cannula system.
