AI Technical Summary
Existing phacoemulsification systems face challenges in managing vacuum surges and pressure fluctuations during cataract surgery, which can lead to potential eye trauma due to uncontrolled fluid diversion and pressure changes.
A processor-controlled three-way rotatable valve system is integrated into the phacoemulsification probe, allowing adaptive control of fluid communication between irrigation and aspiration channels, using sensors to maintain pressure and vacuum levels within specified limits, reducing the risk of vacuum surges and pressure fluctuations.
The system provides rapid response times to adjust fluid flow, minimizing the risk of eye trauma by controlling fluid pressures and vacuums, ensuring safe and efficient phacoemulsification procedures.
