How Sensors Assist Surgeons in Eye Surgery

Pressurization is one of the biggest concerns during eye surgery, including cataract and glaucoma treatments. Eye or intraocular pressure needs to be monitored and controlled precisely and accurately during surgery. In treating refractory glaucoma, for example, the surgical device must be centered on the eye, which requires highly accurate airflow and air-pressure measurement at very low pressures for leak detection. This prevents damage to sensitive eye tissues. 

The Honeywell Basic Board Mount Pressure Sensors, NBP Series, are a cost-effective, basic performance, mV output, unamplified, uncompensated, high quality and high resolution solution for customers seeking high-volume, economical board mount pressure sensors.

In eye surgery applications, it's critical to be able to scale the sensors to a particular airflow or pressure range. By taking a platform approach, the sensor manufacturer can adjust to different flow ranges to quickly customize designs.

A pressure pump, which is used to maintain the pressure on the eye for patient safety, integrates airflow and pressure sensors. An airflow sensor is used to control the air pressure while the pressure sensor is used as a safety valve. Pressure sensors are used to maintain precise pressure and inhibit suction loss to prevent any damage to the patient's eye during surgery.

Pressure sensors that provide pressure range customization, several connection options, calibration, amplification, and temperature compensation can be designed into many different product platforms. This translates into lower costs, faster time to market and reduced assembly time.
