Warnings, Cautions, and Other Residual Risks
• Do not operate the system in a condensing environment (over 95% relative humidity). Take
care to protect the instrument from fluid sprays or fluid buildup. To protect the patient
from contaminated fluids or handpieces, use only:

sterile tubing packs

sterile irrigation fluid

sterile handpieces
• Wrap the excess power cord neatly around the cord wrap on the back of the console.
• Use caution when you use handpieces with sharp edges or pointed tips.
• Always replace the tubing pack and the balanced salt solution bottle between cases.
• Use extreme caution when you lower or raise the balanced salt solution bottle to decrease
fluid flow or increase fluid flow, and fluid pressure.
• If you do not properly prime the I/A tubing, errors can occur.
• Care should be taken to avoid abrasion of tissues during phacoemulsification.
• It is very important that the electrical connectors on the handpieces are completely dry
before you attach the handpiece to the system receptacles.
• The phaco handpiece is a very delicate instrument and you must handle the handpiece
with EXTREME care.
• The ultrasonic titanium phaco tip must never touch any solid material while in use.
• Handpieces can be extremely hot immediately after sterilization. Use care and caution
when handling.
• Do not activate the phaco handpiece and vitrectomy cutter with the tip in the air. Exposure
of the tip to air drastically reduces the useful life of the handpiece. If you introduce power
to the phaco handpiece or vitrectomy cutter, the tip must be in a test chamber filled with
balanced salt solution, in a container of balanced salt solution, or in the patient’s eye.
• Failure to properly attach the tubing to the vacuum source or pressure source can affect
the vitrectomy cutter operation.
• You must check the diathermy cable periodically for damage. If the cable shows signs of
damage, replace the cable immediately with the same type of cable. Use of other types of
cables can affect the diathermy performance.
• During surgery, the diathermy output power must be as low as possible for the intended
purpose. JJSV recommends the 30% setting to start.
• You must position the diathermy cable in such a way that the cable avoids contact with the
patient or other leads. When you use diathermy, grounded or ungrounded metal parts
must not come in contact with the patient.
• For proper operation of the diathermy, replace the handpiece with the same type.
• Do not exceed the maximum weight of two 500 ml balanced salt solution bottles on the IV
pole bottle holder.
