▪ Auto Refractor/Keratometer
The ERK-5400 instantly reports the patient’s assessed eye power by combining the Auto Refractor/Keratometer functions into this one sharp instrument, making measurement a snap. This determines the refractive and keratometric properties of the human eye to assist eye care professionals in the process of prescribing corrective eyeglasses and contact lenses.

▪ Enhanced Measurement of Corneal Diameters
The 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.

Because the ERK-5400 covers a wide measurement range from -25D to +22D, even an examinee with strong myopia can be measured.
▪ Focusing Control Software
In the event that the operator miss focused while measuring the patient’s eyes, the software automatically registers the data as if it were in focused producing the correct measurement data result.

Temperature Control Chip Temperature Control chip is a temperature sensor for precision that detects the internal temperature with each measurement which ensures the precise data.
▪ Advantage of this Chip
Every users will get an exact measurement data regardless of the internal temperature.
This will ensure stability, repeatability, and highly accurate measurement data.
