Description TMS-1 features come back with better resolution, accuracy and easy operation TOMEYs patented light cones use 25 or 31 rings (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.

New TMS Software
TMS-4 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, Asymetry & Higher order irregularity. Fourier Analysis provides the refractive information with 3mm & 6mm diameter range. The software applications, Klyce Statistics, Keratoconus Screen, Enhanced Height and Height Change Map are also available.

Statistical Indices
Simulated K, Minimum K, Average Corneal Power, Potential Visual Acuity, Surface Regularity Index, Surface Asymmetry 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
