Combination automated refraction and topography simplifies pretest room and increases patient flow, Topcon accuracy and robustness.
Topography software feels dated– limited to Windows 7. Beyond basic axial maps and some contact lens fitting, topography software feels limitting.
The 8000PA may be one of the most affordable ARK/Topographer combination units available, despite an aging software platform that will make you want to upgrade.
Combination instrument that perform 3 or more tasks at once are attractive. They save space on the pre-test table, improve efficiency, and typically save in initial investment from buying multiple instruments. And for that reason alone, the KR-8000PA should be an attractive buy for more Optometrists. It offers superior ARK accuracy, basic topography for contact lens fitting, and maintains a compact footprint in the pretest room. It does however require an external computer + software package (from Topcon) which clearly takes the device from one machine, and puts it to another. While the KR-8000PA will perform topography and provide a VERY basic K-Axial Map read-out, it is in black and white, and the scale (of black and white shades) may be difficult to assess. This didn’t give us a lot of confidence when fitting contact lenses with just the unit. The actual display is in black and white itself- utilizing an infrared camera just like that of the basic KR-8000 Autorefractor, however measurements are still easy to take, with auto-align and auto capture. Topcon’s Color Mapping 32 Software is easy-to-use, and produces enlarged color maps, tangential axial maps, sagittal maps, refractive and keratometric data, and peripheral keratometric maps.
