• Extensive amounts of ametropia of the patient may be corrected using
glasses or trial lenses during the measurement. Contact lenses may not
be used for this purpose as they would lead to inaccurate measurement
results.
• The patient should be advised to open his eyelids wide during the mea-
surement to allow best data acquisition.
• Unstabletearlm,tearlmbreakupordryeyesyndromemayleadtoin-
accurateandorinstablemeasurements.Itisrecommendedtousearti-
cial tears in such cases.
• It is recommended to set a user name and password for every user of the
device to best protect sensitive patient data.
• It is recommended and is in the responsibility of the user to protect sen-
sitive patient information using the access control (password protection)
on the device.
1.7 Plausibility of the measurements
WARNING!
• Users must check measurement readings for plausibility. This includes the
checking of the A and B-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 unusually
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.
• If the patient has previously undergone cataract surgery, available records
should be consulted for plausibility check of the measurement
• 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 measure-
ments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 examination.
• 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 impos-
sible to measure corneal thickness, anterior chamber depth, lens thick-
ness 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signicantlydeviatefromspher-
ical surfaces.
• If the device repeatedly generates error messages, stop using it and con-
tact the customer service. These signs must be strictly adhered to, to en-
sure safe operation of the instrument and to avoid endangering users and
patients.
• You are recommended to always examine both of the patient’s eyes. The
user should subject the measurement readings to extra scrutiny if there
is a notable difference between the right and left eye. The following are
classed as notable differences:
•More than 1 D with respect to central corneal refractive power
=> 0.18 mm difference with respect to the corneal curvature radius
• More than 0.3 mm with respect to axial eye length
• More than 1 D with respect to emmetropic IOL refractive power
• The user must check the A and B-Scan when measuring anterior chamber
depth in pseudophakic mode. If only one IOL signal is visible, it is not
clear whether this signal relates to the front or back of the IOL. Uncer-
tainty in this case can lead to the displayed reading for anterior chamber
depth being inaccurate by the thickness of the IOL (approx. ±1 mm).
• The measured corneal thickness is not intended as a basis for the correc-
tion of intraocular pressure readings for diagnosing glaucoma.
• An excessively tilted or decentered IOL may make it impossible to mea-
sure the anterior chamber depth, lens thickness and aqueous depth.
• In young patients the signal from the crystalline lens might be low and
measurement of the anterior chamber depth, lens thickness and aqueous
depth might not be possible.
• Measurement readings obtained from patients with a non-intact cornea
(e.g., due to a corneal transplant, corneal opacity or corneal scarring, etc.)
may possibly be inaccurate (this applies to keratometry in particular), and
the user should check the data for plausibility.
• Ambient light has an impact on pupil-diameter measurement readings.
The user is responsible for ensuring the correct level of ambient light
when carrying out pupillometry. The device does not monitor ambient
light, so do not use pupillometry as the decisive factor when considering
kerato-refractive surgery.
• Keratometry may not be accurate in eyes with keratoconus, and so the
user must verify its plausibility.
• The user must verify that the eye assignment (OD, OS) is correct for the
measured eye.

• The white-to-white distance reading is merely an indirect measurement of
the inner lateral dimensions of the anterior ocular section. It therefore pro-
vides only approximate indications of the actual inner lateral dimensions
of the anterior ocular section and of the size of the implant used.
• The measured results of patients with asteroid hyalosis may not be accu-
rate (in particular the axial length measurement) and must therefore be
veriedbytheuserintermsoftheirplausibility.
1.8 IOL calculation
The measurements taken with the Eyestar 900 may serve as the central element
for the calculation of intraocular lenses (IOL). A further important parameter in cal-
culating the lens to be implanted is the IOL constant. When using the Eyestar 900,
only IOL constants optimised for optical biometers should be used. Please contact
your IOL manufacturer for information on optimised IOL constants for optical biom-
etry. An alternative source of information for IOL constants optimised for optical bi-
ometryisthewebsiteofthe“UserGroupforLaserInterferenceBiometry”(ULIB)
(http://ocusoft.de/ulib/c1.htm).DownloadableIOLConstantslesfortheEyestar
900, featuring the ULIB IOL-Constants for the formulas implemented in EyeSuite
IOL are available in the Key-User section of the Haag-Streit homepage.
To further improve the clinical result, Haag-Streit recommends that every surgeon
creates personally optimised IOL constants based on pre-operative measurement
data generated with the Eyestar 900 and reliable postoperative data (e.g., 3 months
after the operation).
1.9 Optical radiation

2. Introduction
2.1 Basic construction
The Eyestar 900 is an all in one optical biometry device, containing a measuring
head and internal computer for signal processing and display of results. The unit is
operated via a touch screen interface and some buttons at the device housing. Eye-
Suite is the software that runs the unit and is pre-installed on the built in computer.
Integral, automatic error recognition for the measurements guarantees reliable ex-
amination results.
2.2 Operating principles
The Eyestar 900 is a non-contact device consisting of a swept source OCT sub-
unit (OCT: optical coherence tomography, a measurement method to acquire tomo-
graphic images by optical interferometry) and an imaging system sub-unit.
The OCT sub-unit performs a three-dimensional measurement of all refractive oc-
ular structures in the anterior eye segment (curvatures and locations of anterior cor-
neal surface, posterior corneal surface, anterior crystalline lens surface, posterior
crystalline lens surface), as well as a one-dimensional measurement of axial eye
length. It also generates cross-sectional images of the anterior eye section and the
central retina. The measurement is implemented by scanning the eye with a low-
powernear-infraredlaserbeamandmeasuringthelightwhichisback-reectedto
the device. The imaging system sub-unit is used to obtain photographic images of
the eye. Based on these images, the white-to-white distance and the pupil diam-
eter are measured. Additionally, these images can serve to document the locations
of special landmarks on the eye, such as blood vessels. Illumination for imaging is
provided by infrared and white-light LEDs (light emitting diodes).

AD Aqueous depth (Back of the cornea to front of
the lens)
ACD Anterior chamber depth
LT Lens thickness
AL Axial eye length (Front of the cornea to inner
limiting membrane)
NOTE!
Since the device measures up to the retinal pigmented epithelium, the
reading displayed is adjusted to the internal limiting membrane, either
automatically, as a function of axial length, or manually, according to
the mode selected. (Manual correction is not available in the USA).
4.3.2 Keratometry
Thevaluesdisplayed(atradius,steepradius)correspond
totheradiiofanellipsoidthattsintothecornea.Theaxis
of its rotation is measured counter-clockwise from the hori-
zontaltotheatradius.
• e: Flat radius
• f: Steep radius
• g: Axis of rotation
4.3.3 Topography, Elevation and Pachymetry
The device provides the user with surface information of the cornea in the following
formats:
• Anterior and posterior axial curvature map
• Anterior and posterior tangential curvature map
• Total corneal power map
• Anterior and posterior elevation map
• Anterior and posterior irregularity map
• Pachymetry map
4.3.4 White to white distance, pupillometry and eccentricity
of the visual axis
The white-to-white distance (WTW) is determined using the image of the iris and
the eye radii obtained from keratometry. The value displayed corresponds to the di-
ameter of an ideal circle.
WTW
Pupil diameter (Ø) corresponds to the diameter of an ideal circle, with the smallest
error perpendicular to the established pupil border. At the same time, the shift of vi-
sual axis towards the centre of the pupil is provided. The calculated dimensions
are located on the theoretically derived level of the iris. The image enlargement
achieved by the refraction of the eye is disregarded.

distance in meters (m). Field strengths from fi xed RF transmitters, as determined by an electromagnetic site survey a, should be less than the compliance level
in each frequency range b. Interference may occur in the vicinity of equipment marked with the following symbol
NOTE 1: At 80 MHz and 800 MHz the higher frequency applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.
a. Field strengths from fi xed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broad-
cast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fi xed RF transmitters, an electromagnetic
site survey should be considered. If the measured fi eld strength in the location in which this product is used exceeds the applicable RF compliance level above, this
product should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating
this product.

F.5 Safe distances on non-life support devices (standard table 6)
The information is based on the requirements of EN 60601-1-2:2007 (IEC 3rd edition).
Recommended safe distances between portable and mobile HF communication devices and this device.
This product is designed to be operated in an electromagnetic environment in which radiated HF interference is controlled. The customer or user of this product can help to
prevent electromagnetic interference by maintaining minimum distances between portable and mobile HF communication systems (transmitters) and this product, as rec-
ommended below in accordance with the maximum output of the communication system.

For transmitters with a nominal output not listed in the table above, the distance Dcan be calculated in meters (m) using the equation for the respective column, in which P
is the nominal output of the transmitter in watts (W)
NOTE 1: At 80 MHz and 800 MHz the higher frequency applies.
NOTE 2: To calculate the recommended safe distance of transmitters in the frequency range of 80 MHz to 2.7 GHz an additional factor of 10/3was used to reduce the
probability of a mobile/portable communication device causing interference if inadvertently brought into the patient area.
These guidelines may not apply in all situations. Electromagnetic wave propagation is influenced by absorption and reflection of buildings, objects and people.NOTE 3:
