The Tomey TMS‑4N Topographer is an advanced, user‑friendly corneal mapping device that captures high‑resolution Placido ring data to produce precise and reproducible corneal curvature and elevation maps. With over 60,000 analysed data points, this system ensures sharp imaging and accurate measurements with very short acquisition times.

Built‑in software supports single, dual, or multiple map views for comparison and trend tracking, while Fourier refractive analysis provides detailed refractive information including spherical equivalent, regular astigmatism, asymmetry and higher‑order irregularity across clinically relevant diameters. The system also includes keratoconus screening tools, a comprehensive patient database and intuitive multilingual operation for efficient workflow.

Compatible with USB connection and powerful software modules, the TMS‑4N supports contact lens fitting strategies, custom map scales and optional integration with third‑party planning tools — ideal for optometry, ophthalmology, corneal clinics and contact lens practices that require precise corneal evaluation.
