Focus Point at 120Hz

[Tomix89]

Hi,
I am making an experiment in VR using Steam VR, a Vive Eye Pro and SRAnipal.
I need to extract data at 120Hz, for pupillometry and eye gaze hit point in the Unity environment.
Is that possible? I am thinking to use a chin rest, so, ideally the position of the origin of the eye gaze in the world space should be stable.
from my understanding only the Eye data callback is at 120Hz, and the Focus.point can only be called in Update, so at a different Frequency.
Previously, I used a Raycast, but soon realized that the sampling rate I was getting was nowhere near 120Hz.
