NIDEK TonoRef II Autorefractor/Keratometer, Non-Contact Tonometer | INNOVA

The TonoRef II is NIDEK’s 2nd generation 3-in-1 pretesting instrument with combined autorefractor, autokeratometer, and Non-Contact Tonometer functionality bundled into one compact, easy to use instrument.

The TonoRef II features the Pupil Zone Measuring Method which expands the refraction measurement area from 2 mm up to 4 mm in diameter, depending on the patient's pupil size, to get the most accurate measurement. It also uses a Super Luminescent Diode which uses a sharper, clearer measurement ring to penetrate cataracts and IOLs in the objective measurement process.

The Non-Contact Tonometer component of the TonoRef II features the same Automatic Puff Control (APC) that is standard in the stand alone NCTs from NIDEK. The APC reduces the noise and the puff level during measurement to make the process easy for all patients.

The TonoRef II also features 3D Alignment to make measurements simple for even new operators. Simply align the head with the patient's eye and the TonoRef II will take over: tracking the patient's eye until optimal positioning is achieved and acquisition is triggered.


Automated Fundus Camera
Code: AFC 330


Nidek’s new AFC-330 represents a 40-year pedigree of research and development that redefines the science of non-mydriatic fundus cameras. Combined quantum leaps in operator and patient interface, simplicity, automation, and total practice efficiencies, make this instrument a revolutionary advancement in retinal imaging.

Z-View® Aberrometer – Product Information
LET WAVEFRONT PRECISION GUIDE YOUR PRESCRIPTIONS

Utilizing a proprietary, non-Hartmann-Shack technology, the Z-View Aberrometer quickly and accurately measures 2nd - 6th order aberrations of the eye based on 17,000 points of resolution across a 7mm pupil. In approximately one minute the Z-View arrives at a customized prescription.

The Z-View is the world's only binocular wavefront aberrometer. It is a compact, flexible instrument that fits easily into the dispensing practice. The Z-View performs like a high-end surgical aberrometer but at a fraction of the cost.*

The Z-View Employs Advanced Optics Technology For An Efficient and Effective Exam



1). The Z-View is placed either in a pre-exam or exam room.


2). The patient looks into the Z-View at a binocular target.




3). A safe, low power laser is directed into the eye.


4). The light is reflected off the retina through the cornea and lens, and is directed back into the Z-View to measure the wavefront.




5). The wavefront data are used to calculate the optical fingerprint (iPrint(tm)) of the eye, including lower and higher order measurements.


6). The Z-View Aberrometer produces a customized prescription including lower and higher order (2nd-6th) aberrations of the eye.
