To own the Tomey TMS-4 is to own the Topographic Management Software from Tomey. Unlike other self-contained corneal topographers, the Tomey systems rely heavily on external computer/software relationships– the unit is solely a topographic-capture instrument with little choice other than to partner with the included computer. This however isn’t necessarily a bad thing, it just means more space required, and more eyes moving back-and-forth– but aren’t you an eye doctor after all (bad joke)? Tomey’s TMS-4 software is well equipped, and displays are advanced for its original manufacturing timeline. Features such as fourier analysis, contact lens fitting, all-sorts of axial map displays, 3D corneal mapping, and more all make this topographer advanced enough for keratoconus evaluation and contact lens fitting. The TMS-4 software database is well thought out, making it easy to navigate and track progression over time; this is where that external computer makes sense with an advanced database that’s easy-to-use. We also like the high-(enough)-resolution on the axial maps (especially the single-view) that overlay against the corneal capture image; easy-to-read scales and statical indices truly give you everything you need to make a decision on a single screen.
OUR TAKE: External software can be annoying– yet the TMS-4’s advanced external system makes it seem worth it. For a smaller instrument, the Tomey topographic systems (4) bring big power and results.
Single, dual, multiple views with customizable axial maps– preferred-set scale, map type, and so on. Fourier Analysis provides you detailed refractive information with spherical equivalent, regular astigmatism conversion, asymmetry and higher order irregularity. Fourier analysis provides refractive information with a 3mm and 6mm diameter range. The software applications, Klyce Statistics, Keratoconus Screening, Enhanced Height and Height Change Maps are also available- however not included on this particular instrument.
Standard Software 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, and Simulated Keratometric Cylinder Change.
CL Software Standard: User-defined Fitting Strategies, User-defined Lens Designs, Simulated Fluorescein Patterns, Sagittal Tear Film Plots, Adjustment of Position, Rotation and Tilt, User Modifiable Data Base, Order Form Printout, Automatic Transmission of Data to Optical Lab.
The Tomey’s LCD screen does not provide extensive viewing options, however a live-feed of the corneal capture displays during the alignment process.
The Tomey TMS-4 does require constant connection to the included laptop, and will not function as intended without the software (also included) installed and running. The software enables capture from the instrument itself.
Included with purchase, is a remanufactured NIXSYS Laptop running Windows 7. This is the only operating system able to run the program.
The TMS-4 software does in-fact enable auto-capture when the instrument is properly aligned. The alignment is subject to the operator’s movement, and is not motorized nor automatic in its movement.
