Multi-functional Power Auto Ref-Keratometer for the next generation
Refraction & Keratometry Measurement
PRK-5000 provides an extensive range of dioptric measurements. It covers -25D to +22D, and the radius of curvature for keratometry is 5.0mm to 10.2mm. Owing to its easy alignment and friendly operation you can measure the refraction and keratometry in a sequence and the results can be checked all at once.
CLBC (Contact Lens Base Curve)
Base Curve (Posterior curve) of hard contact lens can be measured using contact lens holder on the back of the model eye. You can inspect the lens, or distinguish between the right and left lenses whenever they are switched.
Diameter Measurement
Using the PRK-5000's Freeze Function, you can measure the diameter of the cornea, pupil or hard contact lenses worn. Since the image of the eye is frozen, the process is both easier and more precise.

Optimized Convenience
Operation panel
The innovative design with advanced technologies created compact operation panel. It also includes a power lamp and stage holding knob.
Joystick for easy operation
The PRK-5000 utilizes a convenient omni-directional joystick. Alignment and measurement can be performed with a one-handed operation. Even novice operators can obtain excellent results every time.
Simply press the "PRINT" button, and the PRK-5000 immediately provides a complete printout of the measurement results. For user convenience, built-in printer is located at front-right side of PRK-5000.

The most advanced eye inspector efficiently and promptly inspecting the status of patients' eyesight.
