in vivo measurements

4D Technology has partnered with top contact lens manufacturers to develop custom systems that measure both lenses and lens molds.

4D also works with major organizations to study the corneal surface and the thickness and variation in the tear film. Non-contact interferometry has rarely been an effective tool in measurements involving live subjects, as even slight movement of the subject will render the measurement data unusable. However, 4D’s Dynamic Interferometry technology enables near-instantaneous measurement, which overcomes this limitation and enables high-resolution measurement in real-time of the cornea and tear film.

4D PhaseCam interferometers provide the resolution, vibration immunity and advanced analysis software to aid researchers studying the corneal surface and tear films. The unique instruments aid in studying eye responses to help improve vision correction and to understand complex eye mechanisms.
