retinoscope intended to measure the refract ion of the eye by illuminating the re tina and noting
the direction of movement of the light on the retinal surface and of the refraction by the eye
of the emergent rays.

Insert the Handle of RX-RC into the charging port of RC-II, w hich is exact ly co nnecte d

to the AC power t hrough the AC adaptor, until it stops as shown in the above figure. Be
sure to turn the RX-RC off during charging.

Full charging of battery is completed after approx. 15 hours from an uncharged

condition.

When fully charged the RX-RC can b e illu minate d for approx imate ly 80 minutes at t he

3-2 Turning Illumination ON/OFF

While pressing the Switch button on the Handle,

rotate the Switch ring to the left (towards ON) to
turn the power and light on. (Fig. 3-1)

Since the light adjustment function is built in the

RX-RC, the further t he Switch rin g is rotat ed to the
left (towards ON), the brighter the light becomes.

To turn the light off, rotate the Switc h but ton to the

right until it completely ret urns to the OFF posit ion.

3-3 Varying and Rotating Streak

By shifting the Streak varying lev er upward and down ward based on the re ference line,

it is available to vary the streak as f ollo ws. The reference point on the Streak varying

lever is the top of it.

projected light on fundus of eye slowly and horizontally. On this occasion, scan it

in the direction of perpendicular to the lengthwise dir ec t ion of l in ear streak.
(5) The relation between the motion of reflex and the refraction in condition of naked

3-5 Astigmatic Axis Examination

When the angles of scann ing the examined eye and the moti on of reflex are not related

with the movement or against movement but are the same, this meridian of eye is a
main meridian. If they are not the same, the angle of movement of reflex is a main
meridian, and the meridian w hich is apart 90 degrees from the ma in meridian becomes
the other meridian. Either o f their merid ians is astigmatic axis.

3-6 Dete rmining Refraction

(1) Scan the naked eye and wear in 12mm front of patient’s eye the (+) lens in case

of movement or the (-) lens in case of aga inst move ment (or by using retinoscopy
rank), and find the neutrality point by increasing 0.5 to 1.0D.

* Since against movement is hard to observe comparing with movement, if

against movement exists, more high accuracy neutrality can be obtained by
adding the (-) lenses until movement can be observed and increasing the (-)
lenses step by step.

(2) The relation bet w een t he lens power required for neutralization and the refraction

is shown below.

Refraction = Lens power requ ired f or neutralization –

(1/examination distance[m])
(3) After confirming t he refrac tion of the main meridian, find the neutral ity point of the

other main meridian in the sam e pr ocedures.

3-7 Accessories

(1) Headrest
When performing the examination with

glasses on, remove the cover on t he Headrest
mount to insert the accessory Headrest into
there (see Fig. 3-5). It is hard to scratch the
glasses by operating the RX-RC while putting

the Headrest on your for ehead.
(2) Presbyopic Lens

5-1 Cleaning

If the device becomes dirty , wipe the surface with dry lint-free cloth or lint -free soft cloth

slightly moistened wit h di l uted neutral detergent, an d t hen dr y all surfaces completely.

Disinfection by using alcohol may be carried out at the minimum to clean the surface

As the battery is deteriorated by repeated charges, the bat tery power and the operatin g
time decrease little by little. It is strongly recommended to replace with a new battery
for use of approximat ely 2 years as a guide. The batt ery is replac ed in accor dance wit h
the following procedure.
(1) Rotate the Bottom cap counterclockwise to

detach it and remove the cur r ent bat tery.

When the illumination is not turned on, the bulb may have burned out. In accordance
with the following procedu re, confir m the co ndition o f the
bulb and replace it with a new one if burned out.

(1) As shown in Fig. 5-2, hold t he Head and the Handle

with both hands. Hold ing the H ead, t wist the Handle
