One vision, Two sharp eyes with Our Innovation.

Famous, Traditional, Reliable Topographer.

Corneal Topographer Continues to Set the Standard for Resolution, Accuracy & Corneal Coverage.

TMS-1 features come back with better resolution, accuracy and easy operation. TOMEY's patented light cones use 25 or 31 rings (same as TMS-1), providing high resolution.
The laser alignment system provides high accuracy and repeatability.
The small cone design eliminates nose & brow shadow and provides extensive corneal coverage.
The low light level of the rings promotes patient comfort.

TMS-4N has the comprehensive software: Single, Dual, Multiple and you can even customize your own map with favorite scale, map type and so on. Fourier Analysis provides you the refractive
information with Spherical Equivalent, Regular Astigmatism, Asymmetry and Higher order irregularity. Fourier Analysis provides the refractive information with 3mm and 6mm diameter
range. The software applications, Klyce Statistics, Keratoconus Screening, Enhanced Height and Height Change Maps are also available.

Statistical Indices

Simulated K, Minimum K, Average Corneal Power, Potential Visual Acuity, Surface Regularity Index, Surface Asymetry Index, Corneal Eccentricity Index, Irregular Astigmatism Index, Standard Deviation of Corneal Power, Analyzed Area, Elevation/Depression Power, Elevation/Depression Diameter, Simulated Keratometric Cylinder Change.

Contact Lens Software (Option)
