Autorefractor Keratometer Huvitz MRK-3100P

Easy to use, convenient to measure!!

The Autorefractor Keratometer Huvitz MRK-3100P is so easy to use; there is almost no need for a user's manual, making it very convenient and comfortable for the operator as well as the customer.

IOL Measuring mode

The Autorefractor Keratometer Huvitz MRK-3100P determines the condition of the eyes automatically to detect if there are IOL's or cataracts, and measure them.

Beautiful, clear font

The font is easy to read and stands out, no matter what the background color is. The Autorefractor Keratometer Huvitz MRK-3100P supports multilingual menus (English, Chinese, and European languages ).

Retroillumination mode
  • You can see abnormal crystalline lenses, cataracts, corneas, and scratches on the contact lens with the IR (Infra Red) light that is reflected from the retina. Using this mode, you can determine how healthy the customer's eyes are.
  • We can examine the eyes very precisely because the MRK-3100P supports 4 images (2 images from each eye) and the operator can compare all 4 images at once.
  • The RetroIllumination mode is basically for looking at the eyes. In addition, it is possible for the information to be displayed as Sph, Cyl, Axis, of the eyes.
