From: A machine-independent method to have active removal of 5,000 centistokes silicone oil using plastic infusion tube and 23-gauge microcannulas

Fig. 1

Main steps of the modified method. a After one end of the infusion tube is connected with the syringe’s needle adapter, a small segment about 6 mm is cut off transversely. b Infusion cannula is located at the inferotemporal quadrant. The syringe held by hand is attached to the conjunctiva surface covering the superotemporal microcannula’s cap inside to form a closed space. The hand of core plunger is fixed upwards by a vessel clamp. c Silicone oil is almost removed as the oil-fluid surface exists; the eye is rotated inferonasally to make the microcannula close to the eye’s apex. d Examination of the fundus to ensure no residual silicone oil and no intravitreous management needed
