Grand Seiko Auto Kerato-Refractometer GR-3300K

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.
