3. WARNINGS
The care required in handling the CRYO-LINE surgical system constitutes one of the basic
operating room principles which should always be adhered to, and no list of warnings
can replace such care.
The warnings below provide the operator with suitable instructions to guarantee safe
performance of the system without problems.
General warnings
•Before using the system, all medical personnel concerned must carefully read and
understand the instructions contained in this user manual. Do not attempt to use
the system if it does not work as defined in the operating procedures described
herein.
•The use of the system must be limited to qualified medical personnel who are able
to fully understand the potential risks connected with the use of the instrument and
are suitably trained on the prevention and management of possible clinical
complications.
•Use exclusively dry CO2(Carbon Dioxide) or N2O (Nitrogen Protoxide) gas for
medical use, with a minimum content of 99% and maximum allowable content of
impurities, including humidity, of 1%. The cylinder must be charged to a pressure
not exceeding 70 bar (1015 PSI). Do not use cylinders with a siphon in order to
prevent the gas from leaking from the cylinder in the liquid state. Position the
cylinder vertically with the valve facing upwards.
•Use exclusively gas cylinders equipped with a safety valve for protection against
overpressure.
•Check the mechanical stability of the cylinders. If the Optikon cylinder cart is used,
block the cylinders using the relative retaining spring; if the cylinder cart is not
used, secure the cylinders in a stable manner.
•It is not necessary to use the power cable retainer system if the unit is used in
combination with the Optikon cylinder cart ref. 183001.
•Do not lift or move the footswitch using the cable in order to avoid damage to the
cable.
•Before each operation, carry out the surgical configuration and operating
procedures described herein. Do not use the system if it does not work properly and
the “Troubleshooting Guide" section does not provide a satisfactory solution.

•Before using a surgical or non-surgical accessory with the CRYO-LINE unit, verify its
compatibility with the CRYO-LINE apparatus, declared on the documents attached
to the individual accessories.
•The sound emission capacity of the apparatus is checked at the start-up. Verify that
an acoustic signal is emitted during system initialization.
•The computer connection is designed for technical service procedures only. During
surgical use of the apparatus, do not connect external devices to the serial port
located on the rear panel.
•To avoid damage to the probe, protect the gas connector with the protective cap
before cleaning and sterilization.
•If the probe’s rapid defrost circuit malfunctions, press the Vent button for an
emergency rapid defrost. Notify the Optikon service centre. Do not use the
instrument until it has been repaired.
•To avoid damage to the probe’s cable, do not bend it but wind it up in the
sterilization box with a minimum radius of 5 cm.
•If you notice gas leaking from the probe, do not use the probe; send the defective
probe to the Optikon service centre.
•Use of accessories and cables other than those provided with the unit may result in
an increase of the emissions or in decreased immunity of the system. Portable and
mobile communications equipment can affect the performance of the unit.
•Carefully follow the instructions when installing and using the unit , in order to
prevent harmful interferences with other devices in the vicinity. If the unit causes
harmful interferences to other devices (determined by turning the unit off and on),
the user is encouraged to try to correct the interference by one or more of the
following measures:
•Reorient or relocate the other devices.
•Increase the distance between the equipment.
•Connect the unit into an outlet on a circuit different from that to which the other
devices are connected.
•Consult your local distributor or OPTIKON 2000 technical assistance.
Environmental warnings
•Due to the risk of possible fires or explosions, never use the system in the presence
of open flames.

•Caution: N2O (Nitrogen Protoxide), if inhaled, is hazardous to the health: use the
system only if the gas is evacuated outside the operating room through a suitable
aspiration system.
•To ensure safe operation, do not install the system in a location where it may be
exposed to heating appliances or radiators, direct sunlight or any other source of
heat with extremely high temperatures.
•Install the CRYO-LINE system so that the ventilation openings are not obstructed.
•Do not dispose of the CRYO-LINE unit as non-separated municipal waste. Dispose of
it separately according to local electrical and electronic equipment disposal
laws/regulations.
•Do not use the system in the presence of flammable anaesthetic mixtures with air
or oxygen or Nitrogen Protoxide.
Electrical warnings
•The unit is already set up for use with a power supply voltage of 220V. Check that
the local voltage is the same as that predetermined on the unit. Otherwise, prepare
the unit for the local power supply voltage. In the countries where the local voltage
is 100 - 120 V, replace the fuses of the unit with the appropriate fuses supplied.
These operations must be carried out exclusively by appropriately trained
personnel.
•To reduce the risk of electric shocks, do not remove the protective cover. Request
the intervention of authorised service personnel.
•Connect the console of the CRYO-LINE unit to a mains having the characteristics
shown on the console’s rear panel. To guarantee safety, use a hospital-type power
cord and plug and connect it to a socket equipped with suitable earthing.
•Before connecting the unit to the mains, or disconnecting it, make sure that the
main switch of the console is off.
•When the CRYO-LINE unit is not in use, keep the main switch turned off.
•To allow cooling, the fuses must be replaced after the main switch has been turned
off for a few minutes.
•Replace the fuse with one of the same type, as indicated on the rear panel of the
console.

5. GENERAL INFORMATION
5.1 THEORY OF OPERATION
The OPTIKON CRYO-LINE medical device uses the physical principle of the Joule-
Thomson effect, for which certain types of high-pressure gases, if made to expand
without exchanging heat with the exterior, have a temperature variation that depends
on the initial temperature and pressure, the final pressure and the chemical composition
of the gas. The equation that governs this principle is the following:
0
=
∂
∂
=
H
P
T
µ
where µrepresents the Joule Thomson coefficient. The gases used with the CRYO-LINE
system are Nitrogen Protoxide (N2O) and Carbon Dioxide (CO2), both with a positive
Joule Thomson coefficient at room temperature.
5.2 DESCRIPTION OF THE SYSTEM
The Optikon CRYO-LINE medical device has been designed to be used in ophthalmic
surgery by trained personnel. In particular, the surgical procedures in which the device
can be used are listed below:
•Cataract
•Glaucoma
•Detachment of the retina
•Vitrectomy
The OPTIKON CRYO-LINE medical device uses medical-type Nitrogen Protoxide (N2O) or
Carbon Dioxide (CO2) from cylinders without a siphon in order to obtain freezing
temperatures below –60°C.
The OPTIKON CRYO-LINE device is composed of a control console and a footswitch.
Available accessories include a series of cryosurgical probes, gas filter and instrument
cart with cylinder housing.
Some probes are equipped with a thermocouple that allows to measure the temperature
reached at the end of the probe. The temperature, measured continuously, is displayed
on the console display, in Celsius (°C) or Fahrenheit (°F). The probes are made in
materials with high thermal conductivity so as to be able to cool and defrost very
quickly. The cable of the probe is two metres long.

a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To access the electromagnetic environment due to fixed RF transmitters,
an electromagnetic site survey should be considered. If the measured field strength in the location in
which the Cryo-Line is used exceeds the applicable RF compliance level above, the Cryo-Line should
be observed to verify normal operation. If abnormal performance is observed, additional measures
may be necessary, such as re-orienting or relocating the Cryo-Line unit.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
