1.6.3 Service life of reusable measuring prisms

WARNING! How long can measuring prisms be used? Due to the large number of variables to be considered (type and con‑ centration of the disinfectant used, number of patients, handling, etc.) it is practically impossible to provide exact information on how often and/or how long a measuring prism can be used under safe conditions. The measuring prisms are stamped with an expiry date ( YYYY-MM). They must not be used beyond this date. HAAG‑STREIT recommends a maximum service life of two years before the expiry date. This ser‑ vice life applies subject to normal conditions of use, i.e., in compliance with the instructions contained in these instructions for use. The ser‑ vice life starts with the first use. The above-mentioned time periods do not apply to damaged measuring prisms; these must be immediately replaced.

It is fastened to the microscope on a mounting base and swiveled in front of the microscope for the examination. The observation of the applanated surface is conducted monocularly – only through the left eyepiece. The Applanation Tonometer model T is set on the guide plate over the slit lamp axis, for tonometry purposes. The instrument can be moved between two posi‑ tions on the guide plate for observation through the right or left eyepiece. The sensor arm with the measuring prism projects from the bottom side into the beam path of the microscope and the illumination. The Applanation Tonometer model BQ has a working position and two resting positions. To set the correct angle of incidence of the illumination, the tonometer is swiveled and the illumination apparatus is positioned to the left of the tonom‑ eter bracket. The patient's left and right eyes can be easily examined in this posi‑ tion (no 60° position). The applanated surface is observed monocularly through the right eyepiece of the stereo microscope.

Switching the device on and off

Switch the tonometer on by pressing the function key briefly. We recommend checking the display ele‑ ments regularly to ensure they are functioning when switching the tonometer on. [8.8.8] appear shortly and then each individual LED segment lights up, follow‑ ing by the software version: a 3-digit number. At the same time, the red and green displays will flash alter‑ nately. If a display value appears after that, then the device is ready for use. The digital display lights up and displays the set tonometer value. The tonometer switches off automatically after 90 seconds if no ad‑ justments are made. If the BluetoothTM function is dis‑ abled (Section 5), the tonometer can also be switched off by pressing the function key.

The LED below the display value is used to check whether the measuring prism is within the permitted measuring range during measurement. It lights up red as long as the tonometer is not in contact with the cornea and changes to green as soon as the measur‑ ing prism makes good contact with the cornea. If the tonometer is too close to the eye, the color changes back to red and a warning tone alerts the user to the fact that he/she has gone outside of the measuring range and the sensor is in the safety distance.

How pressure is measured

If [bAt] appears in the display instead of a numerical value when the device is switched on, then the bat‑ teries should be replaced immediately (4x commer‑ cially available 1.5V LR03 (AAA) batteries). You can continue measuring until the tonometer switches off automatically.

The applanation tonometer functions according to the 'Goldmann method': mea‑ surement of the pressure required to maintain a uniform applanation of the surface of the cornea. • The readings obtained are based on the assumption that a cornea with a 'nor‑ mal' thickness is being measured; a different corneal thickness leads to changes in the measured IOP. A 'normal' corneal thickness is considered to fall within the range of 530 to 560 micrometers. • If it is suspected that measuring results may be inaccurate, please conduct a functional verification in accordance with the 'Maintenance' chapter.

Measuring tips

WARNING! Reusable measuring prisms must be cleaned and disinfected after ev‑ ery examination.

5.2 Astigmatism • If the cornea is spherical, measurements can be taken on any meridian, but it is most convenient to measure on the 0° meridian.

• However, the choice of meridian is significant when measuring eyes with corneal astigmatism greater than 3 dioptres, since the flattened area is not circular, but elliptical. • It has been calculated that, in cases of greater corneal astigmatism, a surface of 7.354 mm2 (ø 3.06 mm) is applanated if the measuring prism is at an angle of 43° (A) to the meridian of the greatest radius. Example: If the corneal astigmatism measures 6.5 mm / 30° = 52.0 dpt / 30° and (A) 43° 8.5 mm / 120° = 40.0 dpt / 120° the 120° graduation mark on the prism is set on the mark (A) of the prism holder. If, on the contrary, the measurements are 6.5 mm / 120° = 40.0 dpt / 120° and 8.5 mm / 30° = 52.0 dpt / 30° then the 30° graduation mark is set on the mark (A), meaning that simply the axis position of the largest radius is placed on the mark (A). 10

Preparation of slit lamp and tonometer

1. Press the head firmly against the chin and forehead rests. 2. The patient must look straight forward. If necessary, the small fixing light can be used to steady the eyes. 3. It is recommended that the patient be repeatedly reminded to keep his eyes open wide during the examination. It might be necessary for the examiner to keep the eye open by splaying the eyelids with thumb and index finger. 4. This must be done without applying any pressure to the eye. For all HAAG‑STREIT slit lamps and tonometers 1. Before the examination, the eyepieces must be adjusted correctly to the exam‑ iner. 2. Set the magnification to 10x. 3. Adjust the illumination to medium intensity. 4. Position the blue filter in the beam path of the slit lamp's illumination apparatus and open the slit diaphragm fully. 5. Insert the disinfected measuring prism into the (0° position) holder on the sen‑ sor arm. For Tonosafe, see the separate instructions for use. © HAAG-STREIT AG, 3098 Koeniz, Switzerland - HS-Doc.

Swing the illumination apparatus to the left. 2. Release the tonometer from the dwell position to the right of the microscope, and swing it forward until it locks in the measuring position. 3. From the left, bring the illumination apparatus into contact with the tonometer bearer arm. This is the only illumination position in which both the patient’s left and right eyes can be easily examined (no 60° position). This arrangement fa‑ cilitates the splaying of the patient’s eyelids, should this be necessary for meas‑ urement. The illumination of the applanated surface through the measuring prism is practically reflection-free.

Measuring correctly

1. Immediately before taking measurements, the patient should close his eyes briefly so that the cornea becomes sufficiently moistened with fluorescein-im‑ pregnated tear fluid. 2. By moving the slit lamp, the measuring prism comes into contact with the centre of the cornea over the pupillary area. 3. During contact, the cornea's limbus takes on a bluish glow. This glow can be best observed with the naked eye from the opposite side of the illumination ap‑ paratus. 4. When the limbus glows, stop moving the slit lamp immediately. 5. After contact is made, viewing is conducted through the microscope. The uni‑ form pulsation of the two semi circular fluorescein bands, which could be of dif‑ ferent sizes in drum setting 1 depending upon inter-ocular pressure, shows that the tonometer is in the right measuring position. 6. Any necessary corrections are done using the slit lamp control lever, until the flattened surface is observed in the form of two semicircles of similar size in the middle of the visual field (A).

FRANÇAIS

7. Smaller changes in the depth of the slit lamp using the control lever do not af‑ fect the size of the semicircles. 8. The pressure on the eye is increased by turning the tonometer knob until the in‑ ner borders of both fluorescein bands just touch = correct setting (B). 9. When the eye pulsates, both semi circles cross over each other. 10. The width of the fluorescein band around the contact point of the measuring prism should be about 1/10 of the diameter of the applanation surface (0.3 mm). 11. Display value in mm Hg.

Observation: with model R in the left eyepiece with model BQ in the right eyepiece Model T 1. For an examination through the tonometer’s left or right eyepiece, the angle between the illumination instrument and the microscope should be approx. 60° so that the image is bright and reflection-free. Alternatively: lighting through the measuring prism at approx. 10°.

Allow the patient to close his/her eyes a few times and then repeat the measurement. No semicircular image, only center line is visible (3) The measuring prism is not coming into contact with the cor‑ nea! If the patient draws his/her head back slightly, irregular pul‑ sations will be caused because the measuring prism is touching the eye only intermittently. If the patient pulls back even further, the fluorescein rings will disappear completely.
