For the manual cataract surgery,the patient′s postoperative visual recovery depends on the surgeon′s surgical proficiency,and a laser-assisted cataract surgery experimental system is proposed.The system uses a linear motor to drive mirror to realize the optical path motion,and the focus lens is used to realize the laser single-point cutting of the sample.The mathematical model of the corresponding surgical trajectory is designed for the steps of capsulorhexis and lens fragmentation.The correctness of the mathematical model of the scan trajectory was verified by MATLAB simulation.The cutting experiment is realized using transparent plastic.Experiments show that this system can realize cutting the given cutting trajectory,which provides a new solution for the development of laser eye tissue cutting equipment.
