Objectives To describe a new system for fiberoptic-free bimanual vitrectomy and
to present the outcome of 37 eyes with preretinal membranes due to diabetic
retinopathy or proliferative vitreoretinopathy that underwent surgery using
this system.
Methods The system consists of a 40-diopter aspheric field lens suspended from
the operating microscope and a prismatic inverting device. The aspheric lens
is placed above the cornea, and the illumination from the operating microscope
creates an inverted image of the fundus, which is made erect by an inverter
system. No fiberoptics are required, and both hands are free to use 2 microinstruments.
Main Outcome Measures The practical utility of this system and its surgical results and complications.
Results The system was used successfully in all cases. Membrane dissection and
hemostasis were performed without incident. An improvement in visual acuity
of 2 or more lines was found in 30 of 37 eyes. Five eyes did not reveal change
of 2 or more lines, and 2 eyes had a decrease in visual acuity of more than
2 lines. There was no evidence of phototoxicity.
Conclusion This system is very useful for bimanual vitrectomy.
