ABSTRACT:
A medical instrument captures and removes very large intraocular foreign bodies. The foreign bodies may have an irregular shape, a low coefficient of friction, and be made of non-magnetic materials. A fixed position hollow rod is mounted to a leading end of an elongate base and a lid is mounted to the distal end of the hollow rod. A control rod is slideably received within the hollow rod and a control knob slideably mounted on the elongate base is connected to the control rod to control extension and retraction of the control rod. A silicone basket depends from a rim formed at the distal end of the control rod. A silicone wire interconnects the hollow rod and a bottom of the basket so that the basket is drawn parallel to the control rod when the control rod is extended. The lid covers the basket when the control rod is retracted.
