[0002] Cataract phacoemulsification and posterior capsule polishing are routine steps in ophthalmic surgery, aimed at removing residual lens cortex and epithelial cells to ensure better visual effects. After continuous circular capsulotomy and removal of turbid materials in the capsular bag during cataract surgery, cortical and lens epithelial cells often remain on the posterior capsule. If they are not polished and cleaned, it is easy to cause capsular bag contraction syndrome or secondary cataract after implantation of an artificial lens, affecting postoperative vision. What's more, some patients need examination or treatment due to fundus diseases, but the examination or treatment of the fundus is affected by posterior capsule opacity or contraction.

[0003] The existing posterior capsule polisher is usually composed of a polishing head and a handle connected by a hard pipe. During polishing, the end of the pipe and the polishing head are inserted into the incision of the eye to frictionally polish the posterior capsule. Since it is completely operated by hand, the polishing force is difficult to control and the polishing effect is not ideal. It completely depends on the operating experience of the medical staff. In addition, it is necessary to cooperate with the adsorption handle for adsorption operation.
