Refraction / Keratometry Measurement
PRK-7000 provides a wide measurement range from -25D to +22D for refraction and allows keratometry measurement from 5.0 mm to 10.2 mm. It enables simultaneous measurement of refraction and keratometry with simple and convenient operation, and results can be viewed immediately.

Peripheral Keratometry Measurement
The patient looks at light sources in four directions in addition to the central keratometry measurement. This helps in selecting a suitable contact lens for the patient.
