A New Observation/Illumination System For Vitreoretinal Surgery – Own Experience


The purpose of this paper is to present a new observation/illumination system for vitreoretinal surgery.


Over 400 eyes were treated with the use of optical fiberfree intravitreal surgery system (OFFISS), a device consisting of a 40-D aspheric field lens underslinging the microscope. An inverting device is inbuilt in this system.


The new device could be successfully used and enabled bimanual surgery.


The system is especially useful in removing pr eretinal membranes in diabetic patients, PVR patients and for bimanual peripheral vitrectomy with surgeons own indentation.
