Nidek Tonoref II

Three essential measurements combined in one UNIQUE instrument, the world’s first Auto Refractometer, Auto Keratometer and Non-Contact Tonometer combination unit. This newer, compact, and space-saving device provides a more user-friendly design which allows for enhanced patient flow. The user can easily select patient measurement modes and allow easy access to patient eyelids.

Features

• Improved measurement capability even with dense cataracts and IOL implants
• Pupil Zone Imaging Method – analyses a wider area (max. to 4mm) to obtain more reliable data
• Super Luminescent Diode – for improved quality, clearer and sharper than LED
• New Mire Ring for screening and detecting of corneal surface abnormalities
• Advanced Auto Puff control and noise reduction provides for a more comfortable patient experience.
