Abstract

This report introduces the technique of phaco-emulsification probe real-time tracking for cataract fragments which can eventually realize the using of intelligent control throughout the procedure of cataract operation.The key factors of smart phaco-emulsification techniques are:recognition of cataract and normal tissue;recognition of the color and hardness of cataract;real-time tracking of cataract fragments in the area near emulsifying probe;automatic control of the emulsion probe which could accord to the real-time results to release energy and avoid eye injury caused by over-released energy.The basic to this new method of phaco-emulsification probe real-time tracking for cataract fragments are Hough transform

-nearest neighbor classifier and intelligent control technology.By analyzing the experiment results

this new method realizes the intelligent control of phaco-emulsification operation and improves the operation's safety and efficiency considerably.
