Fast & Correct Various Function

■ Cornea Refractive Power, Cornea Curvature Measurement
Wide area of spherical power from -25D to +22D and cylinder power from -10D to +10D can be measured using specially designed PRK-9000.

■ Cornea, Iris, Cornea Size Measurement
With image capture function of LCD reflected image, cornea, iris, and pupil size can be measured conveniently.

■ IOL Mode
Can measure and observe IOL that is inserted after extracting crystalline lens from cataract.

■ Contact Lens Base Curve (CLBC) Measurement
You can check the proper hard contact lens s base curve with model eye s back side holder and check the condition of the lens surface. That can help you to prescribe exactly for contact lens.

■ Automatic Pupil Distance (PD) Measurement
PD measurement are performed automatically after measuring binocular power, and it displays in LCD windows.

■ Colored Fogging Chart
Patient s eyes can be naturally fogged when measuring their eyes, so control interference can be forbidden. Therefore, measurement reliability can be improved with more exact data.

■ Speedy Printer
A speedy printing can analyze various measurement data easily.

■ Higher Resolution TFT LCD
With 6.4 inch TFT LCD, wide and superior image quality along with colored letters can be provided.

■ Automatic Power Saving Mode
If you do not use the machine for regular hours (you can set the using time from SET-UP mode), the system is changed to the power-saving mode to protect unnecessary power use and overheating of inner circuit.

■ Automatic Chin-Rest Control Function
With one-touch button, you can automatically control the chin-rest, so faster and easier measurement can be possible.

■ Communication Function Among Machinery(Auto Ref-keratometer)
By using RS-232C port, the operator can measure and analyze the data from refractor, lens meter and other machinery
