Abstract: An ophthalmic surgical system includes at least one light source. The light source is configured to output light towards a fluidics cassette so a first portion of the light reflects from a deflectable diaphragm of the fluidics cassette, and a second portion of the light reflects from a reference portion of the fluidics cassette. The diaphragm is configured to deflect relative to the reference portion in response to a pressure associated with a fluid within the fluidics cassette. At least one sensor is configured to receive the first portion of the light reflected from the diaphragm and the second portion of the light reflected from the reference portion. A computing device in communication with the sensor is configured to determine the pressure associated with the fluid within the fluidics cassette based on the received first and second portions of the light. Associated devices, systems, and methods are also disclosed.

Abstract: A microfluidic apparatus for measuring thermo-physical properties of a reservoir fluid includes a first substrate defining a microchannel, an entrance well, and an exit well. The microchannel extends between and is in fluid communication with the entrance well and the exit well. The apparatus further includes a second substrate attached to the first substrate to form a microfluidic device. The second substrate defines an entrance passageway in fluid communication with the entrance well and an exit passageway in fluid communication with the exit well. The entrance passageway is configured to receive the reservoir fluid under pressure. A method of measuring thermo-physical properties of a reservoir fluid includes introducing the fluid under pressure into a microchannel and determining the thermo-physical properties of the fluid based upon the size and concentration of the bubbles formed as the fluid flows through the microchannel.
