Auto Refractor/Keratometer 

The ERK-7800 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-7800 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.
