Pulse Synchronized IOP Measurement The NT-4000 incorporates the “Pulse Synchronized” system for reducing the fluctuation and pursuing more precise measurements. Advanced APC (Automatic Puff Control) Function The amount of air pressure for measurements is reduced by more than 10% compared to the conventional model, for the optimum ease-of-use and patients’ comfort. Expanded Auto-focusing Detection Range The auto-focusing detection range has been expanded more than 50% (compared to the conventional model) in the focusing direction, which allows for quicker and more comfortable measurements. Eyelid Checking Function Before taking the measurement, the NT-4000 checks the position of the eyelid to avoid an error.
