TMS-4 Corneal Topographer
Return to the Classic |
New TMS Software |
| 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 & repeatability. The small cone design eliminates nose & brow shadow & provides extensive corneal coverage. The low light level of the rings promotes patient comfort. |
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. |
