1.Introduction
1.1.Intended Use
The Auto Ref/Keratometer LRK-7000 is intended to be used to measure the refractive power of the eye.
1.2.Equipment overview
Automatic eye examination refractive power measurement device, LRK-7000 is the equipment that
measures refractive power of patient’s eyeball to show Sphere (SPH), Cylinder (CYL) and Axis (AXS)
information. Moreover, it can measure test subject’s corneal curvature and PD (Pupillary Distance,
distance between pupils) and pupil’s size. In particular, it is possible to measure Peripheral Corneal
Curvature separately when measuring corneal curvature, and it enables accurate prescription since it is
possible to know the information of the cornea’s center and periphery curvature individually.
1.3. Grade classification and mentioned items
