1. Features

1. Various Measurements Supported.

Not only the usual refractometry and keratometry, but also corneal

diameter and base curve of contact lens can be measured with this

one instrument. Thus, measurements of eye and prescriptions for

glasses and contact lenses can be made more efficiently.

2. Wide Dioptric Measurement Range

Because theURK-700 covers a wide measurement range, from

-25D to +22D, evenanexaminee with strongmyopia canbemeasured.

3.More accurate Measurement.

8/20/2019 M.I. URK700.pdf

The foggy method of the eye fixation target makes examinee

’s eye

comfortable and enables to getmore accurate measurementdata.

4. EasyConnection with otherEquipments

This instrument is designed to connect other equipments such as VCR

orTV monitor.

2. Notes forUsing the Instrument

1. Do not hit or drop the instrument. The instrument may be damaged

when it receives a strong impact. The impact may cause damage the

influence on the resultof accurate measurement.

3. To connect this with other relevant equipments, consultwith the dealer

about the wayto make it.

4. A sudden heating of the room in cold areas will cause condensation on

the protective glass in the monitor screenand onoptical parts inside the

instrument. In this case, just wait until condensation disappears before

performing measurement.

5. Keep the objective glass of the examinee side clean. If itwas stained, it

maycause onERROR or inaccurate measurements.

6. In case there is smoke, strange odor ornoise on working disconnect the

power supply and consult thedealer.

7. Don

’t use organic solution such as alcohol, thinner, benzene, etc. to

clean the surface of this instrument. Itmaydamage the instrument.

4. Practicing byModel Eye

Practice measurement by using the TestModel Eye before doing the measurement of

patient’s eye.

1 Turn ON thepower

Turn ON the powerswitchonthe lower left side.

2 Setthemodel eye on

Remove the chin rest paper and align the holes on the base of the model eye with the

holes onthe chinrest. Andinsert pins.

3 Release stage lock

Fully turn the bolt in the underneath cover in counter clockwise direction. And turn the

stage holding bolt incounter clockwise directionto release thestage lock.

4 AdjustheightofTestModel Eye.

Adjust the height of the chin rest by rotating Height Adjustment knob so that The Test

Mode Eye is aligned with theHeightAdjustmentmark on theheadrest.

5 Enter K/R or REF Mode

If neither K/R nor REF is displayed on the monitor press MODE button until either one

is displayed.

6 Adjust theposition and focus ontheModel Eye.

Looking at themonitor incline the operation joystick toward the Model Eye until a bright

dot appears near the inner alignment mark. Place the bright dot in the center of inner

alignmentmark. Focus on theModel Eye by inclining theoperation joystick forward and

backward so thatKERATO RING image is displayed clearly on the monitor, at the time

adjusted thebar wouldbeappearedabove the inner alignmentmark.

7 Measurement

Manual measurement

A. Adjust the positionand focus on the Mode Eye like the procedure 6 .

B. Press the measurement button. If measurement is failed with message like

RETRY repeattheprocedure A.andpress themeasurement buttonagain.

C. Check whether diopter value is measured or not. Diopter value is recorded in

thebottomareaof theModel Eye.
