All-In-One
The NIDEK ARK-760A Autorefractor / Keratometer comes equipped with Subjective Refraction Objective and Subjective Measurements, Auto Eye tracking, Auto-Shot and Auto-Print Functions, Cornea and Pupil Size Measurements, High Speed Measurement Function, Calculation & Printout of the Pupillary Distance (PD), Trial Lens Data Printout, Eye Shape Diagram Printout. This instrument has a main body and a measuring unit integrated on one base. On the base is a chin rest on the patient’s side and a printer on the operator’s side which makes an output of measurement results. On the main body is a monitor, a control panel, and a joystick, which are used to make alignments or manipulation. The measuring unit has a measuring window, where the patient looks into and where the infrared ray radiates on the patient’s eye. Also, there is an auto-tracking mechanism which moves the measuring unit to follow eye movement, and an auto-shot function, which makes serial measurement start automatically when the instrument becomes correctly focused.
Features:
- Automatic Alignment, Focusing, Reading, Printing, and Fogging (to prevent accommodation)
- Corneal Size and Pupil Size Measurements
- Visual Acuity Charts
- 180 Separate Retinoscopy Readings
- Capable of Measuring People with IOL’s and Contact Lenses
- High Speed Mode
Visual Acuities
The ARK-760A allows the operator to check visual acuities and perform subjective refinements. It can also interface with the Marco LM-990A or LM-970A Automatic Lensmeter for transfer of data. This allows immediate comparison of objective readings, current prescription and subjective readings.
- (1) Cross-grid Chart
This chart is used to place the unit in the ADD power measurement mode. - (2) R/G Chart
The R/G chart will put the unit in the Red/Green test mode. - (3) Scenery Chart
This chart is used to switch the unit into the objective measurement mode. - (4) VA Chart
The VA chart will allow the operator to test the patient’s visual acuity, at both distance and near. - (5) Dot Chart
The Dot chart will allow the operator to test the axis refinement and the cylinder power refinement using the cross cylinder (XC) test. - (6) Astigmatism Clock Dial Chart
This chart will place the unit in the cylinder test mode. Also used to switch between CYL and AXIS during the cylinder test.
