OPERATION PROCEDURE
3.1 Preparations Use a room with dim lighting (a room in total darkness would be too dark to make the required adjustments). If a special room can not be prepared, use a room without direct sunlight and cover the windows with thick, dark curtains. 1 Then place the instrument so that the patient will not be looking at the window. 2 Connect the power cord (3) to the room receptacle (if it is not already connected). 3 Switch on the power switch (5) and check whether the pilot lamp and illumination scale light up. 4 Set the illumination control switch (6) to the N-position. 5 Adjust the instrument to your eye. First, pull out the eyepiece (13) as far as possible, revolving it counter-clockwise to its limit. 6 Next, place a white paper in front of the mire plate (23) at the position of the patient’s eye, as in Figure 11 and a blurred black circle image will be seen, as in Figure 12a. Revolve the eyepiece slowly clockwise, and stop when the circle image can be distinctly seen as a double circle, as in Figure 12b.

Operation procedure
3.2 Practice measurements with the test ball 3.2.1
Attachment of the column 1 Set the column (27) up in the opening on the chin rest. 2 Then place the test ball (26) on top of the column, as in Figure 14.
Figure 14
3.2.2
Position the instrument correctly before the test ball 3 Adjust the chin rest adjustment knob (19) to fit the test ball into the height mark (24) of the chin rest. Position your eye so that you see the test ball along an extension of a line running through the levelling pin (16) and the black-coloured horizontal index (17). 4 Next, use the joystick (8) to position the test ball along the same line of sight, as in Figure 15.
Figure 15
This will position the test ball and instrument (measuring head) at the correct height.
INSTRUCTION MANUAL
25
Ophthalmometer OM-4
Operate the main body, holding the joystick gently, as shown in Figure 16. Figure 16
The following operations are carried out with the joystick: - Elevation control of instrument. (Rotating the joystick) - Rough horizontal positioning of the instrument. (Slide the main body, holding the joystick) - Accurate horizontal positioning of the instrument. (Lean on the joystick) 5 Next, use the joystick to position the measuring head in front of the test ball, while looking through the eyepiece, so that the mire images show up in the field of view. The mire image in the centre of the field of view will be seen double, as in Figure 17 if the instrument is not positioned at the correct distance to the test ball. Figure 17
The instrument is set to the correct distance when the double images in the centre of the field of view can be merged into a single image by adjusting the joystick. The merged image should be located approximately in the centre of the field of view at this time, but if this is not the case, use the joystick and centre it properly, so that it is concentric with the double images in the centre of the field of view, as in Figure 18.
26
Operation procedure
Figure 18
3.2.3
Measurement Three mire images, as in Figure 19 can now be seen in the eyepiece, and the horizontal knob (11) and vertical knob (12) should be revolved to merge the I mark of the left mire image with the mark of the centre mire image, and the mark of the top mire image with the mark of the centre image, which will give the result of the measurement (see Figure 19), to be read as follows:
Figure 19
Reading of the vertical scale 7.50mm (45.0dptr) Reading of the horizontal scale 7.50mm (45.0dptr) If the reading of the horizontal and vertical scales are identical, it will not be necessary to determine the axis. The test ball is supplied for the purpose of practising measurements, as well as for checking the accuracy of the instrument (which should be undertaken from time to time). The horizontal knob, vertical knob and axis rotating handle (9) can be manipulated with one hand after a little practice. Operating them is even simpler, if the auxiliary knob (10) is attached to the horizontal knob (for a right-handed person), or to the vertical knob (for a left-handed person), as this will simplify operations.

3.3 Measurement of the radius of the cornea curvature 3.3.1
Positioning the patient 1 Place a suitable quantity of pads on the chin rest and fix them in place, with the two pad fixing pins, as in 2.1.5, Fixing the Chin Rest Pads on page 19. Ask the patient to sit in front of the instrument and relax. 2 Next, adjust the Adjustable Instrument Table (ex: AIT-10B "Optional accessory") to fit the point outline for the patient’s eye height, according to the height mark (24) on the chin rest. Adjust the chin rest adjustment knob (19). Place the patient’s chin on the chin rest (20) and the forehead against the headrest (22), as in Figure 20.
Figure 20
28
Operation procedure
3.3.2
Positioning the instrument in front of the patient Carry out the same procedure as for positioning the instrument in front of the test ball; the patient’s eye replaces the test ball here. In other words, position your eye, the levelling pin (16), the black-coloured horizontal index (17) and the patient’s eye along the same line of sight, using the joystick (8) for this purpose if necessary (Figure 21).
Figure 21
1 Next, use the occluder (21) to cover the other eye of the patient. This now gives the same view you are seeing. Once the height of the instrument and the patient’s eye have been properly adjusted in the above manner, use the joystick to produce the mire images. (See Figure 22) Figure 22
If the image is dark and hard to see, turn the illumination control switch (6) to the H-Position. However, do not make the image too bright, as it will not only tire the patient, but also shorten the life of the lamp. In order to simplify making measurements and obtaining accurate results, tell the patient not to move his head. The patient should look at the pupil image reflected in the reflection mirror directly in front of him,
INSTRUCTION MANUAL
29
Ophthalmometer OM-4
without shifting his eyes. The instrument is set at the correct distance when the double images, in the centre of the field of view, merge into a single image with the adjustment of the joystick.
3.3.3
Measurements If there is corneal astigmatism Turn the axis rotating handle (9), as in Figure 23. If there is corneal astigmatism, the mark of the top mire image and the mark of the centre mire image will be seen out of position, as in Figure 24.
Figure 23
Figure 24
Therefore, revolve the axis rotating handle and rotate the measuring head until the marks are no longer out of position, as in Figure 25. (This will result in aligning the measuring head with the axis of the corneal astigmatism.)
30
Operation procedure
Figure 25
Align the I mark of the left mire image with the : mark of the centre mire image and the mark of the top mire image with the mark of the centre mire image at this angle with the horizontal and vertical knobs; this demonstrates how simply and quickly one-position measurements can be made. Figure 26
Read the result of the measurement. In Figure 26, the vertical scale indicates a radius of the cornea curvature of 7.50mm (the refractive power of the cornea is 45.0 dptr) and an axis of 110( (read from the vertical index). The horizontal scale shows that the radius of the cornea curvature is 7.70mm (the corneal refractive power is 43.8dptr) and the axis is 200 (read from the horizontal index.) If there is no corneal astigmatism If there is no corneal astigmatism, the marks will not be out of position, even when the measuring head is rotated. Therefore, carry out the measurement as with the test ball. (See 3.2.3, Measurement on page 27). The measurement results give the value along the circumference of the corneal surface of 2.3mm to 4.9mm diameters (at 5.5mm to 12mm radius of the cornea curvature).

3.4 Measurement of contact lenses 3.4.1
Attachment of the column 1 Set up the column (27) in the opening available on the chin rest (20) as in 3.2.1, Attachment of the column on page 25. 2 Next, fill the hole in the contact lens holder (25) with water and softly press the contact lens to be measured against this section, with the side to be measured on the outside (as in Figure 27a and Figure 27b).
Figure 27
(a)
(b)
Figure 27a demonstrates the measurement of the radius of curvature of the concave side, while Figure 27b shows that of the convex surface. The contact lens will not fall out of the holder even if it is turned upside down, because of the surface tension of the water filling the depression in the holder. The contact lens holder, together with the contact lens, should be placed gently on the column, as in Figure 28. Figure 28
3.4.2
Correct position of the instrument to the contact lens Follow the same operation here as that explained in 3.2.2, Position the instrument correctly before the test ball on page 25.
32
Operation procedure
3.4.3
Measurement Carry out the measurement in the same manner as explained in 3.2.3, Measurement on page 27. However, the measurement results will need to compensate for the radius of curvature of the concave face. Therefore, refer to the "Compensation Table for the Radius of Curvature of the Concave Face," which is supplied with the instrument. In the case of an 8.00 mm radius of curvature, the compensation required, for example, is 0.02 mm. Therefore, the compensation table should be utilised when the required precision calls for its use.

MAINTENANCE
4.1 Changing the lamp If the lamp should blow while the instrument is in use, both the mire plate (23) and the lamp will be quite hot. First let them cool down a bit, and then replace the lamp as follows: Figure 29
1 After switching off the power switch (5) of the power supply unit (4), disconnect the power cord (3). 2 Take a firm hold of the levelling pin (16) and twist it two or three times counter-clockwise, in order to loosen it. 3 Next pull out the mire plate, which will expose the lamp. Twist it counter-clockwise, and detach it.
Ophthalmometer OM-4
4 Insert the replacement bulb and twist it clockwise until it goes no further and is securely attached. 5 Replace the mire plate carefully. The mire plate is notched; therefore, line up the notched section with the alignment pin inside the instrument. Push it in fully and then screw in the levelling pin, which will fix the mire plate securely. 6 Connect the power cord, switch on the power switch, and check whether the illumination lamps light up.
4.2 Exchanging the fuse Figure 30 Fuse holder
1 After switching off the power switch (5) of the power supply unit (4), disconnect the power cord (3). 2 Check the fuses at the rear of the power supply unit. Unscrew the fuse holder with a screwdriver (counter-clockwise) and exchange the fuses.
4.3 Cleaning the instrument ● Cleaning the lenses and mirrors
As a general rule. the surfaces of the lenses and mirrors should not be touched (as far as possible). If they are dirty, try to brush away the dust and dirt with the accessory cleaning brush, which should be stored in the accessory drawer when not in actual use. However, if the lens and/or mirror cannot be cleaned by brushing, wipe the surface with a soft, well-washed cotton or linen cloth, lightly dipped in a solution of 4 parts ether and 1 part alcohol. Do not dampen the cloth

Maintenance
excessively, but repeat if necessary. Furthermore, do not rub the surface but wipe it lightly until the surface is clean. Do not use anything which might scratch the delicate surfaces. ● The gliding plate (7) and rails (18) on the table (2) must be cleaned from
time to time, to ensure smooth movement of the base over the table. ● The plastic parts of the instrument, such as the chin rest, headrest,
etc., should not be cleaned with any kind of chemical solution.
4.4 General care The instrument should not be used in a room which is dusty or damp, or which receives direct sunlight. The dust cover should always be placed over the instrument when it is not in use.
4.5 Before requesting service If something is wrong with the instrument, please check the following points before contacting the authorised distributor for repair. The illumination lamp does not light up
● Check whether the power cord (3) and connector cord (1) are properly
If the ring of the mire plate darkens partially
● The filament has broken, please see 4.1, Changing the lamp on
connected. ● Check the fuses.

FEATURES
Internal reading scales The millimetre scales for the radius of curvature (bottom figures) and the dioptre scales for the corneal refractive power (top figures) of both the horizontal (H) and vertical (V) axes can be seen during measurement, together with the mire images.
Wide range of measurements The range of measurements is extremely wide, with a millimetre scale covering 5.5 to 12.0 mm and a dioptre scale covering 60 to 28 dioptres.
Ophthalmometer OM-4
Highly precise measurements The mire images are very sharp and easy to align, and produce measurement results with the mini-mum of individual variations.
Speedy and accurate focussing adjustments Focussing adjustments are speedy but highly accurate, requiring only the alignment of double images; simple and without individual variations.
Speedy one-position measurement While measuring one of the principal meridians with the TOPCON ophthalmometer, the other principal meridian is also measured; therefore, it is not necessary to measure both principal meridians separately, if there is corneal astigmatism. This makes it faster than twoposition measurement, and also more accurate.
Superior handling ease The horizontal and vertical knobs, as well as the axis rotating handle, are located for simple operational ease and permit one-hand operations. There is an auxiliary knob available for increasing handling ease for both right-handed and left-handed people. Also the joystick can adjust not only the elevation control of the instrument, but also its horizontal positioning.

Features
Inspection of an unusual cornea in irregular astigmatism Inspection is possible by simply checking the shape of the mire images.
