The description relates to a device by means of which an ophthalmologist can provide the same therapy as, for example, with an argon ion laser. Sunlight, however, is used as the light source. An optical "light collector" (telescope (1, 3, 4)) is caused to follow the sun by means of an electronic control circuit. The light received by it is fed into a flexible light-guide (5). After the undesired short-wave component has been filtered out, the concentrated sunlight is applied to the patient with the aid of a lit lamp and the same apppropriate operating components as in a conventional argon arc laser. As a further advantage, part of the sunlight can be used to illuminate the slit lamp so that no electric lamp is needed. The device is intended for use in tropical developing countries. |
