Auto Ref-Keratometer PRK-8000

The optician can easily explain the need for progressive lenses to the examinee. The examinee can experience and compare the difference before and after correction using the near vision simulation function.

By providing an improved ILLUM mode compared to the previous model, the system allows you to observe lens opacity (cataracts) or scratches on contact lenses through the monitor using the light reflected from the pupil.

Compared to the previous model, the LCD monitor has been enlarged (640×480 → 800×480) and can rotate vertically by 180° and horizontally by 135–145°, allowing the examiner to check the patient’s condition directly from various positions during examination.

The device detects the pupil position and automatically adjusts the head height, reducing tracking time and enabling faster output of results. The user can switch between auto and manual tracking with one button.

PRK-8000 offers a wide measurement range of -30D to +25D for refraction and 5.0mm to 13.0mm for keratometry. Refractive error and corneal curvature can be measured simultaneously with easy operation and instant result display.

In addition to central keratometry, the patient looks at light sources in eight directions to measure the peripheral curvature radius, helping in the selection of appropriate contact lenses.

In the size mode, the corneal diameter can be checked for contact lens selection. It shows how much the cornea has expanded, and the lens size can be confirmed even without removing the contact lens.

Up to 10 images and results for each eye can be stored. The improved display control allows viewing of both the image and results at the same time.

By pressing the corresponding buttons on the monitor, up to 10 stored measurement results per eye can be viewed, and printed using the built-in printer.

When a button on the monitor is pressed, the selected button is inverted to confirm the change. The touch screen supports quick and interactive settings, significantly reducing measurement time.

Enhanced measurement light is supported for patients with intraocular lenses or cataracts.

The chinrest moves electrically by pushing or pulling the switch on the upper stage, allowing easy adjustment of patient eye level.

In addition to mire and REF alignment images, a lever operation guide image is provided to help easily locate the eye’s focal position, improving convenience and accuracy.

The joystick, adjusted with zero load, provides a smoother experience and allows precise targeting during up-and-down movements of the head unit, even more stable than the previous belt-type design.
