Directions for the operator of the instrument

X Follow the instructions described here. X Follow the instructions given by your employer regarding the

organization of work and safety at work. Phototoxic damage to the retina during eye surgery WARNING Damage to the retina due to prolonged exposure! The light of the instrument may be harmful. Risk of retina damage increases with the duration of exposure. X During exposure to the light from this instrument, do not exceed the hazard reference values. If the exposure time exceeds the value in the table on page 4 with this instrument at maximum output power, the hazard reference value will be exceeded.

The following table is intended to serve as a guideline and make the surgeon aware of the potential hazard. The data have been calculated for the worst-case scenario: • Eye with aphakia • Completely unmoving eye (continuous irradiation of the same region) • Uninterrupted light exposure, e.g. no surgical instruments in the eye • Pupils dilated to 7 mm The calculations are based on the corresponding ISO standard1) and the exposure limit values recommended in that standard. .

If both illuminations are used, the lower of the two values for the permitted exposure time must be used according to the configured light output. The two hazards do not have to be set off against each other, as their reflections on the retina are not superimposed. This also applies to the use of the Slit Illumination "Phototoxic damage to the retina during eye surgery" on page 4. Slit illumination

Protect the patient with the following safeguards: • Short exposure times • Low brightness settings • Switching off the illumination during breaks in the operation It is recommended to adjust the brightness to the minimum necessary for the surgery. Infants, patients with aphakia (whose eye lens has not been replaced by an artificial lens with a UV protection screen), small children and persons with diseases of the eye are at greater risk. The risk is also increased if the person being treated or operated on has, within the last 24 hours, already been exposed to illumination from the same or any other ophthalmological instrument that uses a bright visible light source. This applies especially to patients that have been examined via retinal photography. Decisions about brightness must be made case by case. In any event, the surgeon must evaluate the risks and benefits of the used light intensity. Despite all efforts to minimize the risk of retinal injury by surgical microscopes, damage may still occur. Photochemical retinal damage is a possible complication of the necessity to use bright light to make eye structures visible during difficult ophthalmological processes. In addition, the Retina Protection function can be activated during the surgery to reduce the main light intensity below 10% and RedReflex below 20%.
