Features:
* 3D Auto Measurement: With Auto Focus + Auto Track + Auto start, the measurement is taken at the most proper position automatically without operating the joystick precisely nor pushing the start switch.
* Auto Start: Automatically starts the measurement once the eye position and the focus are aligned.
* Tilting Large LCD: Operator can be at any position and the large color LCD make the measurement easy.
* Precise Measurement: Improved measurement accuracy with newly designed optical system.
* User Friendly Printer with Auto Cutter: Just throw a paper roll into the printer box without any adjustment and the Auto Cutter makes easy to tear off the printout.
* Simple Lock: Just turn the knob to stop the main unit temporary.It can be put on the slind-ing table safely.
* Electric Chin Rest: The chin rest can be adjusted to the proper level from the operator side with the switch.
* Pupil Diameter Measurement: Useful feature for the subject with Multi Focus Contact Lens and IOL. The pupil diameter at 0.1mm step (minimum 2mm) is measured simultaneously with refractive value.
* Advanced IOL Mode: Improved measurement accuracy of the subject with the cataract and/or the IOL implanted.
* Data Output: The measurement data can be transferred to the external devices by RS232C and USB interface. The data can be retrieved into the spread sheet using Data Collection Software (Optional).
* PD Measurement: In addition to the measurement of Far PD, Near PD is calculated based on it at the selected distance.
* Small Pupil Measurement: Improved system allows to measure smaller pupil diameter as small as 2.2mm and the subject with long eyebrows and smaller eyes can be measured more easily.
* Corneal Peripheral Measurement: Measuring corneal peripheral is useful to determine the base curve for fitting contact lens.
* Tonic Accommodation Measurement: The level of fatigue and its recovery can be measured. This feature is able to prove reliability of far point measurement. Measuring tonic accommodation traditionally required a special settings such as showing empty field to the subject in the special room.
* Contact Lens Selection: In addition to general refraction and corneal data, corneal peripheral, residual astigmatism, and pupil diameter provides more accurate selection of the progressive and large size contact lens.
