Installation 2. To start the installation routine of the software update, click the Update button of the Program tab in the Settings menu. 3. Follow the instructions on the screen until prompted to reboot. 4. Remove the USB flash drive. When the New patient tab reappears in the Patient manager after the IOLMaster has been rebooted, the software update installation is complete.
• Insert the two sleeves (2, Fig. 4) into the two upper drill holes (1, Fig. 4) on the right and left side of the IOLMaster 500 facing the patient. • First insert the pin (3 or 5, Fig. 4) into the sleeve on one side of the holder.
• Now feed the connecting cable (2, Fig. 5) of the Option Reference Image to the center of the head rest. To avoid damage to the cable, pull the IOLMaster 500 back from the head rest as far as it will go (from physician's viewpoint to the left and to the front).

Operation of the instrument Operation of the instrument User's safety obligations CAUTION – GENERAL HAZARDS The patient should not touch the instrument with his/her hands. In particular, the instrument should not be used as a support or an aid when standing up.
Operation of the instrument Measurement and image capture in Reference Image mode A WTW measurement taken preceding the Reference Image mode enables an additional plausibility check of the reference image which may lead to a more successful evaluation of the reference image in certain cases.
Operation of the instrument Fig. 9 Device adjustment to reach optimum measurement position It is recommended that the patient blink shortly before the measurement to produce a continuous tear film. This will improve the reflectivity of the cornea. Make sure the patient’s eyelids are outside the lid aperture edges of the eye template (3, Fig.
Operation of the instrument Several single measurements are taken at short intervals for a single keratometer measurement. Following this, the radii or corneal K's (depending on program settings in the Settings - Measurement tab) of the two main sections will be displayed, together with the respective axial orientation and the astigmatic difference.
The data record can be exported by clicking on the Send icon if the IOLMaster 500 is connected to a network using a DICOM-enabled data management solution. The data record can also be exported to a USB flash drive which is connected to the device.
Operation of the instrument Printing the reference image Once the measurements have been completed, the readings and the reference image can be printed. The following print formats are supported (upright format only): A4 (210 x 297 mm), Letter (8.5” x 11.0”), B5 (182 x 257 mm). The printout of the readings may be started in the Option Reference Image mode.
Application guidelines for Reference Image measurement Application guidelines for Reference Image measurement Evaluation of reference image quality Ambient and room lighting conditions of device location The following information refers to ambient lighting conditions of the location where the device is installed. Minimize variations of ambient lighting conditions e.g.
Application guidelines for Reference Image measurement Stray light from local light sources or lateral sunlight Lateral illumination from local light or reflection sources or from lateral illumination when the sun is low can lead to local reflections or stray light in the sclera.
Application guidelines for Reference Image measurement Eye is not correctly centered The following information refers primarily to the operation of the device. Lateral decentration of the reference image can lead to erroneous evaluations of the reference image quality. Fig. 14 Eye is not correctly centered.
Application guidelines for Reference Image measurement The palpebral aperture is not large enough The following information refers primarily to characteristics of the patient's eye. It may be difficult for some patients to open the eye sufficiently wide. Palpebral apertures which are too small prevent accurate detection of vessels near the limbus.
Application guidelines for Reference Image measurement Excessive eye movements prevent images of sufficient quality from being obtained In some cases, eyes may move considerably during image capture. Excessive eye movements prevent sufficient quality of the reference image. Fig. 16 Excessive eye movements prevent images of sufficient quality from being obtained Error message: "Unstable fixation."...
Application guidelines for Reference Image measurement Few vessels near the limbus In some cases the eye may have not enough vessels near the limbus which prevents detection of a sufficient number of vessels. Fig. 17 Not enough vessels near the limbus Error message: "Not enough vessels near the limbus have been found"...
Application guidelines for Reference Image measurement Fluctuations in keratometer values The precision and repeatability of keratometer measurement values, especially those relating to the axial orientation of the main meridians, are of particular significance for measurements in Reference Image mode. Error message: "Borderline keratometry" Fault Axial variations in single measurements of keratometry values are too strong in relation to the astigmatic difference of the main meridians.
