Topcon Healthcare empowers providers with advanced imaging, diagnostic solutions and intelligent data technology, offering a more fully integrated approach to diagnosis and treatment in eyecare.


Auto Kerato-Refracto Tonometer

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.

Cataract mode
The TRK-2P has a built-in function that allows measurement of patients who have a cataract or an opacity. This function works automatically or manually.

Soft air-puff
Improved nozzle design and software control the optimal amount of air required for every IOP measurement. A softer air puff improves patient comfort and results in an improved measurement experience.

Adjusted IOP based upon pachymetry
The built-in pachymeter function can be used to adjust the measured IOP value, depending on the cornea: if it is thicker or thinner than average. The integrated formula for IOP adjustment can be customized by the eye care practitioner.
