Abstract
The present invention provides a system and a method for managing occlusions and reducing eye tissue damage during phacoemulsification surgery. More specifically, the present invention provides automated control of the application of ultrasonic energy to a partial or full occlusion of a surgical tool. The present invention measures the vacuum pressure and automatically adjusts the application of ultrasonic energy when the vacuum pressure indicates an occlusion or an occlusion break.
Claims8
A system for managing occlusions during phacoemulsification surgery, the system comprising:
- a surgical console having at least one system bus communicatively connected to at least one computing processor capable of accessing at least one computing memory associated with the at least one computing processor;
- and
- at least one vacuum source associated with the surgical console for providing a vacuum pressure and at least one energy source associated with the surgical console for providing ultrasonic energy;
- wherein the ultrasonic energy is adjusted using the formula f(x)=x+ax on a condition that the vacuum pressure exceeds a predetermined pressure threshold for a user adjustable duration,
- wherein f(x) is a new power, x equals a previous power, and a is a constant decimal less than 1.
