Abstract
Official abstract text for this publication.
Methods and systems for automatically pulsing different aspiration levels to an ocular probe are disclosed. The probe may be a phacoemulsification probe. A first aspiration level, supplied by a first pump, may be applied to the probe simultaneously with ultrasonic energy. A second aspiration level, supplied by a second pump, may be automatically switched from the first aspiration level, and applied to the probe in a pulsed manner.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for applying aspiration to a probe device, comprising: applying a low flow-rate aspiration from a first pump to an aspiration port of a phacoemulsification device; detecting that the aspiration port is sufficiently occluded; and upon detection that the aspiration port is sufficiently occluded, cycling a high flow-rate aspiration with a high flow-rate reflux from a second pump to the aspiration port, wherein the high flow-rate aspiration is greater than the low flow-rate aspiration. 2. The method of claim 1 , wherein the cycling occurs for a predetermined amount of time. 3. The method of claim 2 , wherein the predetermined amount of time is abbreviated on a condition that the aspiration port is insufficiently occluded. 4. The method of claim 1 , wherein the cycling occurs to help break up cataract tissue. 5. A method for removing material from an eye, comprising: applying a first aspiration level from a first pump to an aspiration port of a probe within an eye; applying a second aspiration level from a second pump to the aspiration port, the second aspiration level being higher than the first aspiration level; and cycling between the first aspiration level from the first pump and the second aspiration level from the second pump for a predetermined amount of time sufficient to achieve a transient induced effect to break-up the material for aspiration through the aspiration port. 6. The method of claim 5 , wherein the cycling is automatically triggered by detecting that the aspiration port is sufficiently occluded.
