GRK 7000 Autorefractor Keratometer provides you with a more precise measurement of refractive power and corneal curvature
Its various functions make your practice more efficient by improving
Reliable Measurement Accuracy
Optimal Optical System
GILRAS`s unique optic technology offers fast and accurate readings and enhances the reliability of the results.
With auto start mode, the GRK 7000 maintains fogging throughout multiple measurements; that makes it ideal for use with children or other patients who find difficult to fixate on the target chart.
More Advanced Functions
Wide Measurement Range
GRK 7000 Autorefractor Keratometer provides more diagnostic information and superior performance with a wider range of refraction and keratometry measurements.
CLBC (Contact Lens Base Curvature)
Measuring the base curvature of contact lens is useful for contact lens fitting.
PD (Pupilary Distance)
PD is automatically measured when checking both eyes. It saves your valuable time.
VD (Vertex Distance)
VD selection function (0, 12, 13.5, 15mm) offers more accurate measurements data.
More Convenient to Use
The focusing indicator appears on the screen when the eye is the optimal position.
Convenient One - Touch Lock
With the convenient one-touch lock, the main body can easily be fixed to the base.
High Speed Printer
The high speed printer provides a copy of the final measurement results in 3 seconds.
The printing paper can be changed easily by opening the one-touch paper holder.
The system automatically shuts off to conserve energy and prevent overheating.
Realization of a Total Refraction System
GRK 7000 Autorefractor Keratometer can be easily connected to GILRAS Digital refraction system for full integration.
