1. Introduction
1.1. Intended Use
The Auto Ref/Keratometer HRK-9000A is intended to be used to measure the refractive
power of the eye.
1.2. Equipment overview
Automatic eye examination refractive power measurement device, HRK-9000A is the
equipment that measures refractive power of the test subject’s eyeball to show Sphere
(SPH), Cylinder (CYL) and Axis (AXS) information. Moreover, it can measure test
subject’s corneal curvature and PD (Purpillary 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.
Moreover, optimal eye examination information is provided depending on the state of
test subject’s eyes with the following other functions that are provided additionally.
▪VA (Visual Acuity) test
▪Color image observation
▪Light observation with Retro-Illumination
▪Abnormal curve state output via Zernike graph
▪Tear film destruction time measurement

▪Meibomian gland filming function
Automatic eye examination refractive power measurement device, HRK-9000A carries
out automatic arrangement to the X-Y-Z axes (left and right/up and down/front and back)
direction according to pupil to the location optimized for filming including pupil’s automatic
tracking function. Moreover, automatic chin rest adjustment function is provided to
facilitate adjustment of the chin rest’s height, up and down.
1.3. Grade classification and mentioned items
1) Classification of product :
-. EU - Class I with a measuring function according to Annex IX (Rule 12) of the
Medical Device Directive 93/42/EEC
-. KFDA – Class II
2) Resistance against electric shock : Class I (earthed)
3) Protection class against electric : Type B
