Abstract

Extensive clinical evaluation of several vitreous infusion suction cutter (VISC) models demonstrated the need for better internal seals, total waterproofing, and vacuum-tight lines. We designed a new unitized connection to power supply and suction and infusion lines. The power unit has been altered with various safety features. Experimental radio-frequency diathermy was successfully integrated into one of the VISC models, but is not presently recommended for clinical vitrectomy. We modified use of the fundus contact lens. A new fiber optics attachment for intraocular illumination provided very bright light inside the eye and eliminated annoying reflexes.
