During vitreoretinal surgery, the microvitreoretinal blade may be misdirected and injure operating room personnel. A sheated, retractable blade has been developed to reduce the likelihood of such injuries. In the blade's retracted position, a safety feature prevents inadvertent exposure of the sharp blade. This device may have its greatest utility in operating on patients with cytomegalovirus retinitis who require either retinal reattachment surgery or placement of a ganciclovir implant.
