Photocoagulation Through the Goldmann Contact GlassIV. A Second Model of the Attachment to the Zeiss-Oberkochen Photocoagulator and Some Improvements of the Siemens Ruby Laser Coagulator

Arch Ophthalmol. 1969;82(3):314-319. doi:10.1001/archopht.1969.00990020316003

A second prototype of the optical attachment to the Zeiss-Oberkochen photocoagulator allowing the use of the Goldmann contact glass is presented, showing improvements mainly on the observation system by the addition of a slit lamp and allowing for fluorescein funduscopy. Some development of the ruby-laser coagulator described in part II is also reported. A contact glass with a cover glass coated by an antireflection layer is proposed.
