Abstract: Embodiments of the present disclosure generally relate to systems and methods for measuring intraocular pressure (IOP) during ophthalmic surgery. In some embodiments, a method for measuring IOP is provided. The method includes measuring fluid pressure in a fluid flow path of a handpiece device using a pressure sensor disposed therein to obtain a fluid pressure measurement, determining a sensor temperature measurement of the pressure sensor, determining a predicted sensor zero offset based on the sensor temperature measurement using a determined zero offset correlation function, and adjusting the fluid pressure measurement with the predicted sensor zero offset to obtain an adjusted fluid pressure measurement.
