The invention discloses a special phacoemulsification instrument for ophthalmic treatment. The phacoemulsification instrument comprises an ultrasonic handle and a controller, the ultrasonic handle isconnected with a peristaltic pump, the peristaltic pump is connected with a general assembler, an emulsion bottle, a pressure sensor and an ultrasonic generator are respectively connected outside thatgeneral assembler, the pressure sensor is connected with a negative pressure generator, a waste liquid recovery device is arranged outside the negative pressure generator, the structure is simple, the structure is clear and easy to understand, the problems of large operation incision, uncontrollable intraocular pressure and low intelligence degree are solved, the heating of an ultrasonic probe during operation is avoided, the anterior chamber depth is maintained constant, the invention has multiple functions, small incision, good treatment effect and intelligence, and is suitable for microwave treatment fields. In addition, it is very convenient to adjust the suction of chylous fluid and the injection of intraocular perfusion fluid through flow regulator, thus maintaining the dynamic balance of intraocular fluid, which is worth popularizing.
