Abstract
A vitrector for removing material from an eye includes a hand piece, a shaft coupled at a first end to a first end of the hand piece, the shaft having a sharp second end opposite the first end of the shaft, and a cutting device positioned within the shaft and configured for removing the material from the eye. The sharp second end of the shaft is configured for piercing a pars plana of the eye and a sclera of the eye. A method for removing material from an eye includes forming a single opening through a pars plana of the eye and a sclera of the eye using a sharp point of a shaft of a vitrector, cutting the material using a cutting device incorporated within the shaft, and removing the material from the eye using the vitrector.
