the previous patient may be included. ■ Ask the patient to look at the fixation target. If the patient looks in a different direction or moves, alignment may not be conducted correctly. ■ The Auto Alignment function may not work correctly when eyelids and eyelashes cover the cornea.
■ Turn power off and place the dust cover over the instrument when not being used. The measurement accuracy will deteriorate significantly if the optical section in the instrument becomes dirty. Disconnect the power plug from the outlet when not being used for long periods. Dust may accumulate on the plug, resulting in fire.
■ When taking the instrument out of the box, pull the outer box upward and then remove the packing materials. Do not hold the head, chinrest, forehead pad, joystick, or cables when lifting the instrument. Doing so may cause failure or damage to the instrument. ■...
■ Use the power cord and fuses provided with the instrument or specified by Tomey to ensure safety. Also, do not use the accessories provided with the instrument for other equipment.
■ Be sure to turn off the power of this instrument and all instrumens which are connected to it, when connecting a cable from an external device to the connector on the instrument. Failure may occur. 1.1.5 External devices or network ■...
1.1.7 Cleaning and sterilization ■ Peel off the top sheet of chin paper and clean the sections that the patient may touch directly such as the forehead pad with a cloth dampened with ethanol for disinfection before measuring the next patient.
1.1.8 Checks of measured values ■ Fully examine the measured data taken by this instrument, in particular if the difference between measurement values for the left and right eyes is large or any problem is found during the preliminary exmination. When using the data taken by this instrument to select intraocular lenses, thoroughly determine the selection by also examining cataract surgery methods and other inspections.

3.1.3 Starting/shutting down the instrument a) Startup 1) Press the power button. 2) The startup screen and then the measurement screen appear. b) Shutdown 1) Press the power button. The measurement head and chinrest automatically move to the lower dead center and the system closes. 3.1.4 Adjusting the monitor angle The angle of the monitor can be adjusted according to the view height and/or illumination.
3.1.5 Positioning by Touch Alignment When moving an element up, down, left and right using Touch Alignment, touch the panel and release your finger immediately. Do not press the panel continuously. Use Touch Alignment or the joystick to position the patient's eye on the screen. Lightly touch the pupil center of the patient’s eye displayed on the screen.
3.1.6 Positioning by the joystick This instrument is designed to perform measurement in Auto mode to ensure higher accuracy through standard operation. However, Auto Alignment may not be particularly effective when insufficient light is reflected due to deformation or inflammation of the cornea. In this case, conduct measurement manually.
3.2 Measurement Refer to the measurement procedure for each examination. Capture the examination data on the measurement screen. 3.2.1 Basic flow of examination (1) Entering the patient data The patient list screen appears when the instrument is started, measurement is newly taken, the ID button is touched, or the new patient button is touched, and allows you to select a patient.

Peel off the top sheet of chin paper and clean the forehead pad with a clean cloth before capturing images for the next patient. Clean the forehead pad with a cloth dampened with ethanol disinfection as needed. Have the patient place their chin on the chinrest. Adjust the chinrest height so that the height of the corner of the eye is aligned with the eye level mark.

because of a shortage of reflection light due to deformation and/or inflammation of the cornea In this case, switch to manual alignment. (7) Capturing Perform alignment and take measurements with the joystick or the joystick button on the measurement screen. If Auto Shot is turned on, measurement starts automatically after alignment is complete.
3.2.2 Measuring refractive power and corneal curvature radius (Ref- Keratometer measurement) When using the data taken by this instrument to select intraocular lenses, thoroughly determine the selection by also examining cataract surgery methods and other inspections. If incorrect measurement data is used to select intraocular lenses, further surgery might be required.
<Measurement procedures> 1) Switch the measurement mode to "REF/KRT." * Touch the “KRT” button when conducting keratometric measurement only and the “REF” button when conducting refractormeter measurement only. 2) Perform alignment and take measurements with the joystick or the joystick button the measurement screen. If Auto Shot is turned on, measurement will start after alignment completes.

<Measurement procedures> 1) Change the measurement mode to "Topo." * Touch the mode selector button to select “Topo.” 2) Perform alignment and take measurements with the joystick or the joystick button the measurement screen. If Auto Shot is turned on, measurement starts automatically after alignment is complete.
4. TECHNICAL INFORMATION <Correction of intraocular pressure by corneal thickness> It is said that measurement of intraocular pressure represented by the Goldman applanation tonometer is strongly affected by the cornea. This influence can be adjusted with the corneal center thickness (CCT) to some extent. The reported correction formulae are as shown below.
