Disclosed is a device for polishing an intraocular lens by using an electrorheological effect. The device comprises a supporting plate (14), an electric motor (16), a conductive slip ring (18), an outer sleeve (20), a tool shaft (22), a connecting flange (24), an annular electrode (26) and a tool needle (28). The electric motor (16), an outer ring of the conductive slip ring (18), and the outer sleeve (20) are all installed on the supporting plate (14). The electric motor (16) drives the tool shaft (22) to rotate by means of a transmission assembly. One end of the tool shaft (22) is closely fitted with an inner ring of the conductive slip ring (18), and the other end of the tool shaft extends into the outer sleeve (20). The connecting flange (24) is installed on the outer sleeve (20). The annular electrode (26) is connected to the connecting flange (24). One end of the tool needle (28) is connected to the tool shaft (22), and the other end of the tool needle extends out of the annular electrode (26). The tool needle is used as a cathode and the annular electrode is used as an anode in the apparatus. The apparatus thus has a good insulation effect and both tool needle and annular electrode can be detached and adjusted, such that different polishing requirements can be met, and high-quality deterministic polishing for an aspherical intraocular lens can be completed. Further the present invention provides a method for polishing an intraocular lens by using an electrorheological effect.

A polishing device for optical elements includes: a tool shank (1), and a polishing disc base; wherein the tool shank (1) is connected to the polishing disc base and is mounted on a tool shaft of a numerical-controlled processing device; wherein a polishing film (3) is stuck on the polishing disc base; the polishing disc base is a profiling polishing disc base (7), a cylinder polishing disc base (2), a profiling polishing disc base (12) or a spherical polishing disc base (8); wherein the tool shank (1) is independent and universal, thereby reducing the processing cost of the polishing device. A polishing method for optical elements is based on the shapes mentioned above of the polishing disc base, including steps of: fixing a polishing disc connecting rod (11); sticking a polishing film (3); trimming the polishing film (3); and polishing an unprocessed work piece (6).
