Directions for the operator of the instrument

Phototoxic damage to the retina during eye surgery WARNING Damage to the eyes due to prolonged exposure! The light of the instrument may be harmful. Risk of eye damage increases with the duration of exposure. X During exposure to the light from this instrument, do not exceed the hazard reference values. An exposure to this instrument for longer than 1 min 25 seconds at maximum output power exceeds the exposure limits.

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 standards1) 2) and the exposure limit values recommended in them.

Protect the patient with the following safeguards: • Short illumination times • Low brightness setting • Use of protective filters • 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 Infants, patients with aphakia (whose eyelens has not been replaced by an artificial lens with a UV protection screen), small children and persons with diseases of the eye are at greater risk.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.

Floor stand • Always push the instrument to move it; never pull it. Feet in lightweight shoes could become trapped beneath the casing of the base. • The footbrakes must remain engaged throughout the operation. Electrical connections

The control unit may be opened only by a Leica-approved service technician. Accessories

Only the following accessories may be used with the Leica M822 surgical microscopes: • The Leica Microsystems accessories described in this User Manual. • Other accessories, provided that these have been expressly approved by Leica as being technically safe in this context.

The decision about which light intensity to use for an application must be made on a case-by-case basis. 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. 6
