1. Features
Intended Use
An autorefractor/keratometer is used to determine the refractive and keratometric
properties of the human eye to assist eye care professionals in the process of
prescribing corrective eyeglasses and contact lenses.
Various measurements supported
Not only the usual refractometry and keratometry, but also corneal diameter and
base curve of contact lenses can be measured with this one instrument. Thus,
measurements of eye and prescriptions for glasses and contact lenses can be
made more efficiently.
Wide dioptric measurement range
Because the ERK 7800 covers a wide measurement range from -25D to +22D,
even an examinee with strong myopia can be measured.
More accurate measurement
The fogging method of the eye fixation target makes examinee’s eye comfortable
and enables getting more accurate measurement data.
Simple and convenient user’s environment
Delivers more convenient user environment with wide-
view 6.4” color LCD screen
and with simple and easy-to-understand design.
Illumination for observation
This allows for observation of the eye condition of the cataract or contact lens
surface. The system saves up to 2 images of each eye.
Easy connection with other equipment
This instrument is designed to connect other equipments such as LCD Monitor
