1. Introduction
1.1. Overview
Auto Ref/Keratometer HRK-7000A is the equipment to provide the information of
Spherical, Cylindrical and Axis while measuring the refraction of examinee’s eyes. Auto
Ref/Keratometer HRK-7000A is the equipment that can measure the corneal curvature
of examinee. In addition, it can measure PD (=distance in between pupils) and pupil
size. Especially, as its peripheral (=corneal peripheral curvature) measurement is
possible as measuring the corneal curvature of examinee, it is possible to know the
information on the corneal peripheral curvature as well as the corneal core curvature,
which enables the exact prescription for the examinee.
This equipment shall provide the optimal optometry information with the functions of IOL
(=measuring intraocular lens) and Retro-Illumination (=observing retro-illumination) to
obtain an optimal figure of the eyes’ state of examinee.
CLBC (Contact Lens Base Curve) measurement is also a basic function of this product.
The HRK-7000A is provided with an Auto-tracking function and a motorized chinrest
function.
Auto-tracking mechanism that automatically achieves alignment in the up/down,
right/left direction and focusing.
A motorized up/down chinrest allows the operator to easily adjust the height of the
chinrest.
