A vitrectomy cutter apparatus and method. The apparatus (and method) is efficient in facilitating removal of vitreous humor during intraocular surgery such as a vitrectomy procedure for the human eye. The apparatus includes an exterior cylindrical member with ports substantially separately and/or oppositely disposed from each other. An interior cylindrical member reciprocates within the exterior cylindrical member to cut vitreous received via the separately disposed ports. The interior cylindrical member includes a funnel-shaped distal end and a spiral cut axially to reduce friction between the external and internal cylindrical members.
