What’s included
- Nidek Tonoref RKT-7700 Autorefractor Keratometer Tonometer
- Power Cable
Advanced & Innovative World’s First Combination Model
Auto Ref/Keratometer & Non-Contact Tonometer in One Unit – The Nidek Tonoref RKT-7700 is the world’s first combination model of an auto ref/keratometer (ARK) and a non-contact tonometer (NT). Combining the measurements of refractive power, corneal curvature, and intraocular pressure (IOP), the device provides faster and more accurate patient care in clinics and hospitals.
Fast & Accurate
High-Speed & Reliable Measurement – With NIDEK’s advanced technologies, the Tonoref RKT-7700 provides highly accurate, reliable, and fast measurement with significantly reduced measurement time.
Fully Automatic
3D Auto-Tracking & Auto-Shooting – The auto-alignment *X & Y directions), auto-focusing (Z direction), and auto-shooting provides faster, simpler, and more accurate measurements. When alignment is performed correctly, measurements start automatically.
Printer with Automatic Paper Cutter – The ARK and NT data can be automatically separated when printing.
Optimized Operability
From alignment and measurement to data printing, all operations can be easily achieved with the user-friendly joystick of the Nidek Tonoref RKT-7700
- Tiltable LCD Monitor – The clear 5-inch TFT color LCD with a tilting function offers easy operation even for a standing operator. The standing operator can still see the monitor while lifting the patient’s eyelid to help open the eye.
- Motorized Chinrest – Up/Down buttons for the motorized chinrest
- One-Touch Lock – The upper movable part of the unit can be fixed with the advanced one-touch lock.
Patient Friendly
- Softer Air – The Nidek Tonoref RKT-7700 advanced APC (Automatic Puff Control) function provides softer air for IOP measurement, providing increased patient comfort.
- Safety First—Patient Detection Sensor—When a patient is in front of the unit, the chinrest does not move while calibration and initialization are ongoing.
