The TRK-2P combines a refractometer, a keratometer, a non-contact tonometer and a pachymeter in one compact instrument. The TRK-2P features a fully auto alignment system with auto measurement function. The compact size and 8,5” rotating color touch screen control panel offers total flexibility for the operator and also for instrument location. With just one touch of the fingertip on the control panel, the TRK-2P will measure both eyes accurately due to Topcon’s exclusive Rotary Prism Technology.
