Editor’s note: The current authors tested a novel minimally invasive vitrectomy technique, through one-port pars plana sclerotomy using 25-gauge instruments. They used an anterior chamber maintainer and transpupillary illumination to perform simple vitrectomies in eyes that appear to have had pre-existing posterior vitreous detachments. The slit-beam on a microscope was used with a wide-angle contact lens system and 25-gauge micro-instrumentation. Indentation was used to examine the peripheral retina, and the patients were rendered aphakic during surgery with later implantation of a lens implant to aid wide-angle viewing. However, the technique seems of limited value, with increased risk of reduced interior examination of the eye for the sake of one sclerotomy.
