With Auto Focus + Auto Track + Auto St art, the measurement is taken at the most proper position

automatically without operating the joystick precisely nor pushing the Start Switch.
Auto Start
When the position and the focus are aligned, the measurement is taken automatically for the required number of times.
Once both eyes are measured, the results will be printed out automatically.
Tilting Large LCD
With this Large Easy to read Color LCD, measurements can be done easily and quickley 
Precise Measurement
With the newly designed optical system, the measurement accuracy is excellent.
User Friendly Fast Printer (with Auto Cutter)
Simple Lock  system
Electric Chin Rest
Pupil Diameter Measurement
Simultaneously with refractive value, the pupil diameter at O.lmm step (minimum 2mm) is shown on the LCD and can be printed out.
It can measure the pupil diameter necessary for Multi Focus Contact Lens, IOL.
Advanced IOL Mode 
With the improved measuring system even the cataract and the IOL implanted subject can be measured much more easily.
Data Output
With RS232C and USB Inteliaee, the measurement data can be sent to the external devices.
With the use of Data Collection Software (option),
 The measurment data can be  sent as spreadsheet data.
PD Measurement .
Measures the Far PD Near PD is calculated accordingly (select working distance from 30, 35, 40, 45cm). 
Result can be printed out as NPD if required.
Small Pupil Measurement
Compare to the previous model it measures smaller pupil of 2.2mm diameter 
Corneal Peripheral Measurement
With the measurement of Corneal Peripheral, the base curve of the contact lens can be chosen more precisely.
Contact Lens Selection
With the addition of corneal peripheral. residual astigmatism and pupil diameter data to the general refraction
and corneal data, the accurate selection even for the progressive and the large size contact lens now becomes much easier.
Tonic Accommodation Measurement
The fatigue during near distance work and its recovery can be judged. At the same lime, reliability of far point measurement can be confirmed.
Traditionally, it must be measured in a special room by showing an "EMPTY fiELD".
