Refraction and Keratometery Mode
PRK-7000 provides an extensive dioptic measurement range (-25D to +22D), and the radius of curvature for keratometry is 5.0mm to 10.2mm. Easy alignment and friendly operation allows you to measure the refraction and keratometry in sequence, and the results can be validated immediately
Peripheral corneal curvatures can be measured by having the examiner look at the peripheral eye fixation lamps. Measuring the corneal periphery will help you examine irregular astigmatism, and also determine a better fitting for a contact lens.
Intuitive Diameter Measurement
Using the freeze function, measurement of the diameter of the cornea, pupil or hard contact lens worn by the patient can be performed. By simply touching and dragging the screen with your finger, exact measurements are calculated.
When the refraction results in an error reading due to an intraocular lens or cataract, the measurement can be performed with the IOL icon switched ‘ON’.
Touch Screen Control
By adopting a high resolution VGA TFT-LCD with Touch Screen functions. we have virtually removed all input keys except the measurement button on the joystick and the chinrest control switches. Tests are performed rapidly and conveniently by simply pressing a button or the icon indicated on the screen.
