摘要：
FIELD: medicine.SUBSTANCE: invention refers to ophthalmology. It involves inserting ports, introducing a light guide, carrying out vitrectomy, detaching an epiretinal membrane (ERM), unbending it, cutting and removed by using a vitreous cutter. It is combined with matching a longitudinal axis of the port for the vitreous cutter directed towards an edge of the ERM with generating a surgical axis (SA), matching a vitreous cutter axis and a longitudinal symmetry axis of the ERM with generating a surgical plane (SP) an external surface of a vitreous cutter tip is delivered under a retinal surface of the ERM to perform asynchronous oscillatory movements about a centre of oscillation with the positive to negative amplitude ratio within the range 1.5 to 1.0 the centre of oscillation is moved along an external curvilinear surface of the ERM each stage of discrete movement involves moving the vitreous cutter tip along the SA and in the SP 2-3 mm front, then 1-2 mm with the vitreous cutter tip advanced along the retinal surface of the ERM to an opposite edge of the ERM, increasing an area of the detached retinal surface of the ERM to start thereby formation of a rectilinear tunnel in a vacuum mode of 200-300 mm Hg, an upper wall of the ERM tunnel is fixed in a vitreous cutter window, while the ERM is pulled upwards then the vacuum level is dropped to zero, and the vitreous cutter tip is moved along the SA and in the SP again forward to formation of the tunnel 4-5 mm long the vitreous cutter tip is delivered under an external border of the tunnel the vitreous cutter window is brought to contact with an upper wall of the tunnel then the vitreous cutter tip is advanced in a cutting mode along the tunnel in the EMR with dividing the EMR on two equal flaps further a bleeding is directed from a new vessel found close by a macular region coated with connective tissue bridges and membrane-like structures towards the macula with turning an eyeball in relation to the surgical plane wit
