• All users must be appropriately trained and familiarised with the contents
of the instructions for use, especially with regard to the safety instructions
contained therein.
• Measurements can be carried out with dilated or undilated pupils. Dilation
of the pupil only inuences pupillometry.
• We recommend checking the calibration of the optional T-Cone when t‑
ting it and repeating this if necessary (see section "Function check").
NOTE!
• This device may only be used for the purpose described in these instruc‑
tions for use.
• Installation only by trained specialists.
• The PC on which the EyeSuite software is installed may not contain any
other software which could restrict the correct operation of EyeSuite.
• Please switch the computer off if it is not to be used for a long time.
• The device may not be transported, stored or operated outside the speci‑
ed ambient conditions (see section "Ambient conditions").
• The device is to be used in a room in the medical area with attenuated
light.
• If the device or accessories to it are exposed to the effects of an exter‑
nal force (e.g., by being accidentally knocked or dropped), this sensitive
measuring device must be promptly checked according to section “Func‑
tion check” and, if necessary, returned to the factory for repair.
• If the device is moved/transported, a functional check must be performed
in accordance with section "Function check".
• Perform a zero adjustment and function check when prompted by the
software.
• The selected measuring mode must be checked before every measure‑
ment.
• Keep these instructions for use in a place where they are accessible at all
times to those working with the device.
• Warranty claims can only be made if the instructions for use have been
complied with.
• The manufacturer of the device is not liable for loss or damage due to un‑
authorised handling of the same. All warranty claims arising in this case
are null and void.
• Always remove the dust cover before switching the device on. The light
sources can be destroyed by overheating. Likewise, make sure that the
device is switched off before attaching the dust cover.
• Repairs may only be conducted by suitably trained and authorised spe‑
cialist personnel. Incorrect repairs can pose considerable risks for operat‑
ing staff and patients.
• Only original spare parts and original accessories may be used
for repairs.
• The software must be installed by trained personnel.
• The optional T‑Cone may only be used with the Lenstar.
• The optional T‑Cone may only be used with Lenstar devices with a serial
number of
≥
2000 or Lenstar devices converted to white light illumination.
• The optional T‑Cone must be checked for damage before use.
• The optional T‑Cone must not be exposed to strong direct sunlight.
1.6.1 Plausibility of the measurements
WARNING!
• Users must check measurement readings for plausibility. This includes
the checking of the A‑scan and the cursors, which automatically adjust
to the signal, the keratometry values, the white‑to‑white distance and the
pupillometry, whenever one of the measurements displays an unusual‑
ly high standard deviation. The operator must also take into account the
type (e.g., posterior subcapsular cataract) and density of the cataract
when evaluating plausibility.
• Prior to the measurement, the user must verify that the patient is not
wearing contact lenses. Wearing contact lenses will result in erroneous
measuring results.
• It may not be possible, under certain circumstances, to carry out mea‑
surements on persons with xation problems.
• In cases of thick cataracts and uncertain measurement of the axial
length, ultrasound biometry should be performed as a control examina‑
tion.
• Dense lenticular opacities may make it impossible to measure the axial
eye length and lens thickness.
• Pronounced opacities of the central cornea can likewise make it impossi‑
ble to measure corneal thickness, anterior chamber depth, lens thickness
or axial eye length.
• Blood in the vitreous may make it impossible to measure the axial eye
length.
• Keratometry may be erroneous in eyes that have undergone keratore‑
fractive surgery because such eyes may signicantly deviate from spher‑
ical surfaces.
• The user should make a visual check when carrying out the measure‑
ment procedure, to ensure that all light spots are present.
• If the device repeatedly generates error messages, stop using it and con‑
tact the customer service.
