4 in 1 System
HTR-1A has the Cornea Thickness, IOP, and Refractive Power which are essential functions for Eye Clinic, it can measure the indispensable data for the Customized Lens prescription
Compact Design
By compact design and size, HTR-1A is possible to save users' space. 4 measurements from 1 device, patients don't need to move their places and it can save their time as well


Full Auto Tracking & Shooting
As long as the measuring point is placed in the automatic tracking range, it can trace and shoot the pupil measuring point by the 3D drive mechanism. By clicking the button once will be measured the binocular precisely and efficiently
