Phacoemulsification Using Image Processing

Abstract: phacoemulsification apparatus having a phacoemulsification probe that has a needle with a distal tip configured to be inserted into an eye lens, the needle having a lumen. the probe has an actuator configured to vibrate the needle, an aspiration channel, coupled with the lumen and configured to convey an emulsified particle of the lens as aspiration fluid, and an aspiration sensor, coupled with the aspiration channel and configured to measure a vacuum level within the aspiration channel. a microscope is configured to capture an image of the distal tip and of the emulsified particle. a processor is configured to provide an analysis of the image, and, in response to the analysis, when the emulsified particle is in contact with the distal tip for at least a preset time period while the vacuum level is below a predetermined threshold, energize the actuator with a pulse of energy.
