Three exclusive features of Focus / POTEC Auto Ref-Keratometer   RELIABLE & ACCURATE REF / KER measurement, Wide measurement range Multi-function, User-friendly.   SLIM & SMART Compact body for space saving.   HIGH QUALITY & AFFORDABLE Cost effective pre-test solution meets or exceeds many other brands.
Reflection sight/Measurement of cornea curvature PRK-5000 provides an extensive dioptric 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.   CLBS (Contact Lens Base Curve) Base curve (posterior curve) of hard contact lens can be measured using contact lend holders on the back of the model eye,You can inspect the lens, and distinguish between the right and left lenses.   Diameter Measurement Using the PRK-5000's Freeze Function, you can measure the diameter of the cornea, pupil or hard contact lenses worn by an examinee. Since the image of the eye is frozen, the process is simple and precise.
Automatic PD Measurement The Pupil distance is automatically measured and displayed after refraction measurement of both eyes is performed. Automatic Power Saving When the PRK-5000 is not in use more than 5 minutes, a built-in power saving function eliminates current to the TV monitor and lighting circuitry. It conserves energy and prevents the build-up of heat from electronic circuitry, extending instrument life.       Color Photo Target This color photo target with wide angle of view allows the examinee to be more relaxed, making eye fixation easy. The auto-fogging function reduces the effects of instrument myopia and patient accommodation, especially helpful with children and patients with difficult eyes.       Direct results indication Through the monitor, you can see the results (maximum of 10 data for each eye) of measurements stored in memory. Data may be printed.
Operation Panel Along with the innovative design and advanced technologies, the compact control panel provides easy access to all measurement modes.   Easy handling joystick PRK-5000 utilities an omni-directional joystick. Alignment and measurement can be performed with one-handed operation. Even novice users can obtain reliable and accurate data every time.   Printer Simply press the "PRINT" button, and the PRK-5000 will immediately provide a complete printout of the measurement results. A lightning fast, built-in printer is located to the right side of the joystick.   Transmission of data Measurement data can be transferred to external devices (personal computers, etc.) via RS-232 interface.
