1. PRIOR TO USE Š

Make sure that the instrument is free from any equipment that may cause an intensive magnetic field, which otherwise causes the instrument with noises or may make it unable to allow correct diagnosis or measurement.

Š

Care must be taken not to place any object on the instrument.

Š

Be sure to read this Manual before using the instrument for your safe and correct operation.

Š

Do not use the instrument in any procedures other than specified in this Manual.

1.1 Precautions „

„ „

Though measuring accuracy is +/- 5 µ m, accuracy with actual measurement may be out of the measuring accuracy, depending on condition of cornea. Please review and retake the measurement or try other inspections, when the result seems to be suspicious with past corneal medical history of the patient. Only skilled operators are allowed to use this instrument. When installing the instrument, observe the following items. - Install the instrument in a place where it is free from water and/or chemicals. - Install the instrument in a place where it is free from such adverse influences as direct sunbeams, high temperature and moisture, dust, and salts or sulfur-contained air. - Install the instrument in a stable place where it is free from inclination, vibration, and/or shocks. - Do not install the instrument in or near the store area of chemical substances or a place where any gas is generated. - Use specified frequency, voltage and allowable current (or allowable power consumption). - Make sure that the conditions of power source (discharge, polarity, etc) are proper.

1.1 Using precautions

1-1

„

Observe the following items before using the instrument. - Check on the settings of switch connections, polarity, and volumes and make sure that the instrument operates accurately. - Make sure that all the cord connections are made properly. - Recheck the components or parts that directly touch the Patient.

„

Observe the following items when you use the instrument. - Avoid using an excessive period of measurement for each Patient. - Closely and continuously watch to check to see if the instrument works in normal condition and the Patient is secured in safe condition. - If any abnormal condition is found with the instrument or the Patient, take appropriate actions or remedy, first to secure Patient's safety and next to stop the operation of the instrument. - Sufficient care should be given not to cause the Patient to touch the instrument while the instrument is in operation. Observe the following items after using the instrument. - Before turning the power off, return the instrument to its original condition in specified procedure. - Do not apply undue force to the power cable when disconnecting, such as by pulling the cord itself. - As for storing the instrument and related components, see "5.4 Storage" in this Manual. - Store the Pachymeter Probe, accessories, and cords in order after cleaning them properly. - Be sure to properly clean the instrument to be ready for your next use. It is advised that in case the instrument is disorderd, stop using the instrument and contact your TOMEY representative for corrective inspection and/or repair. Do not uncover except battery cover or remodel the main instrument in any ways. Do not remodel or redesign the instrument, or the Warranty will be invalid. Periodical inspection should be given to the instrument and related components. When using the instrument after recess for a while, make sure that it operates properly and safely. Please USE AC power adapter provided from TOMEY as SP-100 standard accessory. When using other AC power adapters, the warranty will be invalid and the unit may not work properly.

1.4 Outline of Measurement Principle Š

After taking measurement, the oscillator is not emitting ultrasound waves.

The SP-100 is designed for pachymeter or corneal thickness measurement by using ultrasound transducer, built in Pachymeter probe. z SP-100 emits the ultrasound from the Pachymeter probe and the probe also receives the ultrasound reflected by surface between corneal posterior face and anterior chamber. z SP-100 measures the period of time from emitting ultrasound to receiving the same ultrasound, reflected by corneal posterior part. Applying a calculation formula shown below, corneal thickness can be calculated. V·t L = --- 2 Where,

L: Corneal Thickness V: Converted sound velocity (Ultrasound Velocity through cornea) T: Measured time (Ultrasound transmission time between emitting and receiving)

z This instrument is powered by rechargeable battery or AC power adapter. Even when the battery power is running short, SP-100 can perform measurements, while charging the battery, by plugging to AC power adapter. z This instrument is designed to take corneal thickness measurement automatically, when the probe is applied to cornea properly. z This instrument is capable of sending and receiving patient information and measurement data between the external equipment through the serial communication port. (Additional cable must be used, when using this function)

Optional components

Assembling of the Disposal Tip Pachymeter Probe and alternative Probe shapes The Disposal Type Pachymeter Probe (supplied as an optional component) consists of the inner probe, case, fixed ring, and disposal tip. The Probe can be changed in two alternative shapes: (A) with 45 shape and (B) in straight shape, depending on the application convenience.

<How to assemble> 1) Cover the inner probe A with a pair of cases B to make the inner probe clipped in between and fix it with the rubber rings C. 2) Apply a small amount of methylcellulose (such as Dry Eye Gel) on the tip of the inner probe A. 3) Then securely insert the disposal tip D not to cause air bubbles inside of the tip. <How to assemble the Probe in alternative shape> 1) Disassemble the disposal tip D, fixed ring C, and the case B in order. 2) Assemble the case B to be changed and next fix it with the rings C. 3) Next apply a small amount of methylcellulose to the tip of the inner probe. 4) Then securely insert the disposal tip D not to cause air bubbles inside of the tip.
