Nidek Tonoref II Auto Refractor/Keratometer 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.
