The Slit Lamp And The Laser In Ophthalmology - A New Laser Slit Lamp

The paper presents a new design of ophthalmic slit lamp which has been especially constructed for use in laser photocoagulators. A solution to various problems arising in existing systems, the optical possibilities for precisely controlling the spot diameter and an easier method of operating the manipulator will to discussed. This slit lamp offers all manufacturers of argon, crypt on and dye photocoaqulators a unique optical interface.

Observations On The Optical Construction Of A Q-Switched Neodym YAG Laser For Ophthalmology

A major problem in using pulsed Neodym-YAG-Laser-Systems for ophthalmic break-down surgery is to supply a sufficient aiming beam which gives the operator a precise indication of the point of interaction, independent of multiple reflections within the anterior segments of the eye. In addition to that, to minimize side-effects, an optical solution to achieve a high cone-angle will be presented. These results will be shown as performed in a recently introduced system.
