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 unauthorised 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
device may otherwise become damaged due to overheating. Like-
wise, make sure that the device is switched off before attaching the
dust cover.
• Repairs may only be conducted by suitably trained and authorised

• Extensive amounts of ametropia of the patient may be corrected us-
ing 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
measurement to allow best data acquisition.
• Unstable tear film, tear film breakup or dry eye syndrome may lead
to inaccurate and or instable measurements. It is recommended to
use artificial 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
sensitive patient information using the access control (password pro-
tection) on the device.
• If unexpected disturbances are observed the cause could be a cell
phone or radio frequency telephone in the immediate vicinity to the
Eyestar 900. Increase the distance to the device until the interfer-
ence disappears.
1.6 Plausibility of the measurements
WARNING!
• Users must check measurement readings for plausibility. This in-
cludes 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 meas-
urements displays an unusually high standard deviation. The operat-
or 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 measure-
ment.
• Prior to the measurement, the user must verify that the patient is not
wearing contact lenses. Wearing contact lenses will result in erro-
neous measuring results.
• It may not be possible, under certain circumstances, to carry out
measurements on persons with fixation problems.
• In cases of dense cataracts and uncertain measurement of the axial
length, ultrasound biometry should be performed as a control exam-
ination.
•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 im-
possible 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 ker-
atorefractive surgery because such eyes may significantly deviate
from spherical surfaces.
• If the device repeatedly generates error messages, stop using it and
contact the customer service. These signs must be strictly adhered

to, to ensure safe operation of the device 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 radi-
us
◦ 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 vis-
ible, it is not clear whether this signal relates to the front or back of
the IOL. Uncertainty in this case can lead to the displayed reading
for anterior chamber depth being inaccurate by the thickness of the
IOL (approx. ±1 mm).
• An excessively tilted or decentered IOL may make it impossible to
measure 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 kerato-
metry in particular), and the user should check the data for plausibil-
ity.
• Ambient light has an impact on pupil-diameter measurement read-
ings. The user is responsible for ensuring the correct level of ambi-
ent light when carrying out pupillometry. The device does not monit-
or 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 measure-
ment of the inner lateral dimensions of the anterior ocular section. It
therefore provides 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
accurate (in particular the axial length measurement) and must
therefore be verified by the user in terms of their plausibility.
1.7 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 calculat-
ing 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 biometry. An
alternative source of information for IOL constants optimised for optical biometry is
the website of the 'User Group for Laser Interference Biometry' (ULIB)
(http://ocusoft.de/ulib/c1.htm). Downloadable IOL Constants files 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).
WARNING!
It is the user's responsibility to use correct values of personalised IOL
constants.

2Intended purpose / intended use
The EYESTAR 900 is a non-invasive, non-contact biometer used for obtaining fol-
lowing information:
• Corneal shapes
• Axial eye length
• Lens dimension and position
• Anterior chamber dimensions
• Front- and cross-sectional images
The device indications for the use are measuring biometry data necessary for lens
implant surgeries and measuring biometry data for analyzing the anterior chamber.
2.1 Device description
The Eyestar 900 is a non-contact device for measuring the human eye, consisting of
a swept-source OCT sub-unit (OCT: Optical Coherence Tomography, a measure-
ment method to acquire tomographic images by optical interferometry) and an ima-
ging system sub-unit. Both measuring methods, OCT and digital photography, are
non-invasive and contactless.
The OCT sub-unit performs a three-dimensional measurement of all refractive ocu-
lar structures in the anterior eye segment, as well as a one-dimensional measure-
ment 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-reflected to the device. The imaging system sub-unit is used to obtain photo-
graphic images of the eye. Based on these images, the keratometry, the white-to-
white distance and the pupil diameter are measured. Additionally, these images can
serve to document the locations of special landmarks on the eye, such as blood ves-
sels. The imaging system sub-unit is based on conventional digital photography
technology. Illumination for imaging is provided by infrared and white-light LEDs.
Measurement of keratometry additionally requires measuring the distance to the eye
using the OCT sub-unit.
2.1.1 Intended users
Users are qualified medical professionals such as ophthalmologists, optometrists,
opticians, nurses and researchers or other qualified specialists as permitted by local
legislation. The interpretation of biometry data is restricted to professionals with the
appropriate educational background as permitted by local legislation.
2.2 Medical purpose
This device has the following medical purpose:
• Investigation of the anatomy of the eye.
2.2.1 Indications
The use of this device is indicated for the following medical conditions:
• Cataracts
• Corneal irregularities
• Lens irregularities
• Refractive errors
2.2.2 Part of the body
This device is intended for the examination of the human eye.
2.2.3 Patient population
This device is intended for use on human patients with the physical ability to sit in
front of a biometer with their head resting against the headrest in a steady position
and the mental ability to follow instructions. Patients must be at least 6 years old.
2.2.4 Contraindications
There are no known contraindications.
2.3 Principles of operation
• The device uses contact-less measurement technologies: a OCT system to
measure 3D volumetric data of the patient eye and a imaging system for LED
Keratometry, iris and pupil measurements.
• The OCT system bases on Fourier domain interferometry and is able to capture
the complete eye length with its long coherence swept source. A two-axis
MEMS mirror scans the light beam across the patients eye.
• The device imaging system takes true color pictures and is also sensitive for in-
frared light. Therefore, white light and infra red LED's are placed on the patient
interface as well as on the measuring head.
• The measuring head with parts of the OCT and imaging system is mounted on a
motorized 3-axis positioning system inside a non-accessible housing.

2.3.1 Operating environment
This device is intended to be used in professional health care facilities such as hos-
pitals, physician's, optometrist's and optician's practices. For optimal use of the
device, the ambient lighting should be attenuated.
2.4 Clinical benefit
Anatomical measurements of the eyes serve as basis of information for any medical
condition related to the divergence of these measurements from known standards.

fractive surgery patients benefit from the refined IOL calculations.
The clinical benefits of the product outweigh the remaining residual risks to the pa-
tient.
