CAUTION - RISK OF MEASURING ERRORS Measurements should never be performed through contact lenses, as this produces incorrect results. The wearing of rigid or soft contact lenses may have an effect on the surface geometry of the cornea and thus the optical state of the eye. For measurement of wearers of soft lenses using IOLMaster a rest period of at least two weeks should thus be observed from the time the contact lens is removed to the time of measurement. For wearers of rigid lenses the time from removal of the lens to the time of measurement should be at least three weeks. Avoid measurements of eyes with retinal detachment. In such cases, measuring errors cannot be precluded. Avoid the use of eye drops prior to measurement, as they may lead to incorrect results, in particular in the measurement of corneal curvature. Do not perform anterior chamber depth measurements on pseudophakic eyes. Do not perform any contact measurements or examinations in which the eye is touched. They may result in incorrect readings, particularly for axial length and corneal curvature measurements. Contact measurements or examinations should only be performed after the patient has been measured with the IOLMaster. Do not use the IOLMaster in patients with the following conditions: • Unable to steadily fixate the fixation lights with the eye under examination (e.g. in the case of nystagmus, extremely poor visual acuity, lack of concentration) • Unable to follow the instructions of the user • Unable to sit upright in front of the instrument • Deficient specular reflection of the cornea for keratometry or anterior chamber depth measurements (e.g. distortion of the tear film, scarring or caustic burn of the cornea) • Complete or partial covering of the cornea caused by closed or inadequate coverage of the pupil • Forehead or chin injuries that prevent the head from being supported on the forehead/chin rest • Morphological changes of the retinal anatomy in the region of the fovea for axial length measurements (e.g. retinal detachment, edema, ulcer) • In the case of low transparency of the optical media of the eye (e.g. mature cataract, opacity of the posterior capsule, hemorrhage in the vitreous body) it may be difficult to measure the axial length (see also information in the software description).

Intended user profile CAUTION - RISK OF OPERATING ERRORS This device may only be installed, operated, used and maintained by persons who have been properly trained or who have the required knowledge and experience to do so. Please adhere to the additional national qualification guidelines applicable in your country.

Operators of the IOLMaster should have knowledge of basic eye examination and diagnostic procedures. The following pre-requisite skills are recommended for operators of the IOLMaster:

Technicians or personnel performing measurements with the IOLMaster • Performs medical (eye) history and screening procedures • Provides patient instructions during measurement procedures • Observes acoustic and optical warning signals and displays on medical devices • Uses computers and computer interfaces (USB, Ethernet, VGA) • Familiar with the Microsoft Windows operating system and applications based on it • Performs maintenance, cleaning and calibration procedures on medical devices

Physician’s assistants, nurses or other personnel performing data processing In addition to the skills required for performing measurements, the user should have knowledge of pathological factors that influence measurement quality, in particular: • Cataract-related light scattering of optical media • Corneal opacity-related light scattering of optical media • Optimization of instrument settings, to minimize pathological factors that influence measurement quality

Performance specifications

Performance specifications Functional description The IOLMaster is a combined biometry instrument for measurements on the human eye required for the preoperative computation of intraocular lens power. It is capable of consecutive measurement of the following eye parameters in one session: axial length, corneal curvature, anterior chamber depth and WTW distance. All measurements are non-contact, providing excellent patient comfort. The axial length measurement is based on an interference optical method known as partial coherence interferometry (PCI). The displayed results of the axial length measurements are comparable to the ultrasonic immersion measurements of axial length via the use of an internal, statistically verified calculation algorithm. The familiar formulas for IOL calculation can thus be used. However, the lens constants must be changed for use with the PCI method. Manufacturer's constants are less suitable. Please consult the scientific literature on this subject. The corneal curvature is determined by measuring the distance between reflected light spots projected onto the cornea. The anterior chamber depth is determined as the distance between the optical sections of the lens and the cornea produced by lateral slit illumination. The WTW distance and pupil diameter are determined from the image of the iris.



Depending on the brightness, the pupil size can fluctuate greatly during measurement. The readings may not be used to plan further treatment.

The individual measurement procedures are automated, so that the operator is only required to adjust the instrument to the patient’s eye and initiate the measurement. For this reason the complex biometric procedures of the eye can rapidly be mastered with the IOLMaster, but should be practiced with the greatest of care and attention to detail. Extensive integrated safety features (independent redundant hard and software safety features) ensure maximum safety for both the patient and operator when using the IOLMaster. The control program for the computer in the device base runs under Microsoft Windows. A backlit LCD serves to observe the patient’s eye and display the readings. The instrument is controlled using the joystick and computer keyboard with integrated touchpad.
