title: Vitreoretinal dissection set.
abstract: We developed and evaluated a vitreoretinal dissection set consisting of six microspatulas, a specially designed micro-olive tip, an internal drainage cannula, and a master handle. The microspatulas, which have a spear-headed shape with blunt edges and flat, smooth surfaces, offer a range of angulation from 60 degrees to 160 degrees as well as options for front, back, or tip opening for irrigation or aspiration purposes. All parts can be used through conventional 20-guage or 19-guage sclerostomies, and they all fit on the same handle as well as on any Luer lock system. This set allows for mechanical and/or hydraulic dissection, membrane engagement by suction, and simultaneous use of probe with scissors or forceps. It has been proved safe and effective in more than 100 vitrectomies, including cases of diabetic tractional detachment, proliferative vitreoretinopathy, retrolental fibroplasia, and macular pucker.
