Auto Refractor/Keratometer
The ERK-9000 combines all of the necessary visual pre-testing functions in one smartly designed instrument. Operators can perform refractometry and keratometry alone or simultaneously. The ERK-9000 is also quick. In fact, not even the unwanted effects of patient accommodation will stand in your way thanks to the unit’s valuable built-in auto-fogging mechanism.

Auto-Shoot Programming
Users can program the ERK-9000 to shoot at their preferred mode. One click on the joystick button can take a single measurement, three continuous measurements or five continuous measurements.

Simple and Convenient User Environment
The ERK-9000 features a user-friendly dashboard view. Sharp images with easy-to-understand icons make this 7.0-inch color TFT color touch screen LCD interface enjoyable to work with.

IOL Mode
Patients presenting with cataract or IOL won’t present a challenge with the ERK-9000. In fact, now you can gather a wealth of information about natural lens opacity as well as take measurements on patients who have intraocular lens implants.

Illumination Mode
The Enhanced Illumination Imaging capability in the ERK-9000 is very helpful in determining ocular health. You can check for scratches and other corneal damage as well as check for lens abnormalities such as cataract.

Easy Network Capability
