IOL Power Calculation – Haigis Suite

Target refraction

IOL power calculation formula

Refractive index

The Haigis Suite is a combination of four formulas: Haigis, Haigis-L for post LASIK cases, Haigis-T for toric IOL calculation, Haigis-TL for toric IOL calculation for post LASIK cases. Depending on the lenses selected (i.e. toric and or non-toric IOLS) Haigs and Haigis-T are applied. For toric IOLs, Haigis-T will be applied and for spheric IOLs Haigis will be used. Both toric and non-toric IOLs can be calculated at any time and simultaneously.

Composite Values: AL, ACD, LT with Standard Deviation (SD)

Spheric IOL

IOL constant(s) of relevant formula

Composite Value: K Flat, K Steep, Cylinder

IOLMaster 700 – Quick Guide

Please note: This document is a preliminary version and does not replace the user manual which is delivered together with the device. Final version is to be released soon.

WARNING - GENERAL HAZARDS

These quick instructions are intended as an overview. Instructions for the safe operation of the instrument are to be found in the user manual and online help.

Always perform measurements in the correct sequence! All device measurements must be performed before undertaking any measurements involving direct contact with the eye.

Calibration test

• Always check the calibration daily before carrying out measurements on patients!

• Tap the Start button to start the first of three calibration test steps. The test eye in the chin rest compartment will rise up automatically.

• Now carry out the measurements on the test eye. Follow the instructions on the screen. The overview shows the individual steps of the calibration test and their status

• If the Calibration test was passed, press the button ”next” and the application will be started.

• If the Calibration test was failed, repeat the calibration test by pressing the button “repeat”.

New Patient

• New patient data can be entered by tapping the Add button. The following information is required: Last name, first name, Gender (Gender drop-down box), Date of birth (Open the Date selection box and select the patient's day, month and year of birth. Confirm with OK.), and Refractive Surgery.

• It is important that the correct lens state and vitreous body state are selected as this cannot be changed after the measurement has been done. If changes are necessary, the measurement needs to be repeated.

• An existing patient dataset from the patient list on the left side of the screen can also be selected.

• Input field for entering a search string Parts of the patient name, ID or date of birth may be entered for the search.

• With the buttons “Analysis”, “IOL Calculation” and “Measurement” the according dialogs screens are opened.

Measurement Coarse alignment

Fine alignment

Fixation

• Coarse alignment: The measuring head is coarsely adjusted on the pupil center. Usually the measurement head is moved towards the eye from a position further away of the eye. The reflective pattern of the six LED test marks must be in the center of the cross hair and focused. A WTW image is captured here to detect the iris edge. Instruct the patient to look steadily at the fixation point in the center and ensure that the device head is aligned as accurately as possible.

• Fine Alignment : For fine adjustment, the reflective pattern from 18 LED test marks is focused by moving the measurement head closer to the eye. In addition to the live image, the vertical (right of the central live image) and horizontal (on the bottom of the central live image) OCT scan is represented. In each image, an adjustment area is proposed (shown in green). If the alignment is correct, a yellow dot is displayed within the green rectangle of the adjustment area in the horizontal and vertical OCT scan image. Measurement is triggered automatically or manually depending on the selection made earlier. In this measurement step also the reference image or sclera-image is captured. To capture a good sclera image, it is important that the patient opens his/her eyes wide, the lighting in the room is not too bright and the vessels in the patient's eye can be recognized (no sclera image is captured if vessels cannot be recognized). In the Measurement dialog area of Advanced settings you can enter the value of corneal astigmatism which determines a clinical indication. If this value is reached, a sclera image is automatically triggered.

• Fixation: The Fixation follows the same principle as the fine alignment. The difference is that only 6 LED test marks need to be focused.

• Measure other eye / repeat Measurement: You can repeat the current measurement (button “repeat measurement”) or measure the other eye after moving the measuring head to the other eye using the joystick. After finishing the measurement the Quality-Check is complete.

Quality-Check

Successful measurement: A green quality indicator shows a technically perfect measurement

Warning for uncertain measurement: A yellow quality indicator will signal to the user that he/she should verify the corresponding measurement marks thoroughly

Measurement failed: A red quality indicator means that no measurement results could be detected

The quality check helps to evaluate the quality of the measurement. From the application point of view, the user should check whether the measured values are correct and plausible. This can be done by using the analysis window. In addition the Fixation of the patient should be checked. Good fixation is shown by a depression in the center (right picture), the so-called foveal pit. If the foveal pit can be easily recognized, the patient fixated well during measurement. If it cannot be recognized (left picture), the patient has not correctly fixated. In this case, measurement should be repeated and the patient be instructed to fixate on the fixation light in the device. If the patient cannot fixate during several measurements the user should verify if there may be another problem with the patient which requires special examination.

Analysis

The following images are displayed in the analysis dialog separately for the right and left eye: - Biometry-Scan - Keratometry-Scan - WTW-Image - Sclera- Image - Fixation Check. They should be checked for artifacts in B-Scans, WTW and sclera images which are out of focus or deformed or missing spots in keratometry. The measurement values for the right eye are shown on the left side (OD) and the measurement values for the left eye on the right side (OS) of the screen. Measurement values should be checked thoroughly for plausibility. Warning messages should be read with caution.

IOL Calculation

• For each eye, the IOL calculation is done separately. For better orientation, the measurement data of the selected eye are displayed on a white background, the data of the other eye are greyed out. Additionally, the selected eye is shown in bold and green letters in the upper right corner of the display.

• Tap the measurement data area on the right or left side of the screen to alternate between the eye or use the

button . Beneath the measurement data, the lens state and refractive surgery history is shown for each eye.

• Tapping and select the calculation formulae to be applied.

• IOL calculation is started by tapping . To be able to print or export to FORUM, always an IOL calculation has to be done.

• By tapping Finish/ Print / Export (view can vary according to individual setting), reports will be printed / exported and the application will jump to the Patient Manager where other patients can be opened and / or additional measurements can be done.

• The measurement values can be edited by tapping the appropriate field. Edited values are marked with an *. If the IOL calculation window is closed, the entries will be canceled. When re-starting the IOL calculation, the measured values are displayed in these fields.

Shutdown

Tap the X (Close) button to open a menu with options for logging out the current user or switching the device off after finishing all measurements.
