Auto Kerato-Refractometer KR-8100PA

Auto Kerato-RefractometerKR-8100PA
 

By installing a 3D auto alignment function, measurement can be made easily even by an unskillful operator.
Rotary prism unique to TOPCON is mounted allowing high-accuracy measurement and measurement of small pupils 2.0mm in diameter.
Mapping function most suitable to those wearing contact lenses is also available.

One multifunctional auto kerato-refractometer performs objective refracting power measurement, cornea curvature radius measurement and cornea shape mapping display.
A measurement system by placidoring is used for measurement of cornea radius of curvature. Accurate measurement by all-round data of ten rings is assured. The rings have wide measurement ranges from 1.5 to 9.2mm in diameter.
In only 4 seconds, measured mapping data is displayed on the display screen of the unit. Additionally a memory of placidoring image is displayed, cornea shape mapping is displayed and overlaying mapping onto the anterior segment can be shown.
If an anomaly is detected with the cornea shape during measurement, a message will be displayed. Mapping can be measured without interruption during kerato data measurement when an anomaly is detected.
A TV monitor and video printer can be connected. An image can be zoomed on the monitor screen and a placidoring projection image of a measured eye can be printed out for an explanation and recording.
Cornea shape mapping measurement will display reference values of an appropriate base curve from data of the entire cornea for fitting of a contact lens.
Data processing of data measured by the KR-8100PA by connecting the meter to a personal computer installed with Color Mapping Software 32 will display a cornea shape in colors allowing easy viewing. This will be useful in understanding a cornea shape, contact lens fitting, early detection of a cornea surface anomaly and examination of astigmatism after surgical operation. (Option)
