Refractometry & Keratometry Measurement
PRK-8000 provides an extensive dioptric measurement range [-300 to +250) compared to our previous model, and the radius of curvature for keratometry is 5.0mm to 13.0mm. Easy alignment and friendly operation allows you to measure the refraction and keratometry in sequence, and the results can be validated immediately. Owing to its easy alignment and friendly operation which you can measure the refraction and keratometry in a sequence, the results can be checked all at once.
Peripheral Keratometry
Peripheral corneal curvatures can be measured by having the examinee 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 lenses worn by the patient can be performed. By simply touching and dragging the screen with your finger measurements are exactly calculated.
Enjoy world’s Fastest Measurement speed
World’s fastest measurement is provided through greatly improving its speed as compared to our previous products and the products of our competitors.
Simulating short-distance vision
An optician can help a patient easily understand if he or she needs to wear progressive lens through pre-correction vision simulation. The patient can compare the effects before and after correction through short-distance vision simulation.
Enhanced performance of Retro illum
With our improved I LLUM mode, any opacity[cataract] in the crystal or fault of the contact lens are visible on the monitor by the method of projecting light on the pupil.
