⭕ The Topographic Modeling System TMS-4 is a device that provides information about corneal configuration and refractive characteristics. Unlike conventional keratometers, this device employs color maps incorporating the most modern computer technology, to permit easier and more accurate diagnosis than conventional devices. The TMS-4 has a Light Cone keratoscope with a short working distance, therefore it is easier for the operator to lift the patients eyelid. Remarkable features of the TMS-4 are the auto shot system that facilitates operation and the wide variety of clinical applications developed in the long history of the TMS series. Approx.3 years old.
