Product Description

  • USB connection
  • Auto shot function
  • Large Patient Database
  • Easy Database Operation
  • Multi-Language Operation
  • Fourier Refractive Analysis
  • Quick Data Reference
  • Built-in LCD Alignment
  • Keratoconus Screening & Other Applications
  • High Resolution for Accuracy & Corneal Coverage


TMS-4 features come back with better resolution, accuracy & easy operation TOMEY’s patented light cones use 25 or 31rings (same as TMS-1), providing high resolution.
The laser alignment system provides high accuracy & repeatability.
The small cone design eliminates nose & brow shadow & provides extensive corneal coverage. The low light level of the rings promotes patient comfort.
The TMS-4 has the comprehensive software: Single, Dual, Multiple & you can even customize your own map with favorite scale, map type & so on. Fourier Analysis provides you the refractive information with Spherical Equivalent, Regular Astigmatism, Asymmetry & Higher order irregularity. Fourier Analysis provides the refractive information with 3mm & 6mm diameter range. The software applications, Klyce Statistics, Keratoconus Screening, Enhanced Height & 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
User-defined Fitting Strategies, User-defined Lens Designs, Simulated Fluorescein Patterns, Sagittal Tear Film Plots, Adjustment of Position, Rotation & Tilt, User Modifiable Data Base, Order Form Printout, Automatic Transmission of Data to Optical Lab.
