Diode laser modifications for treatment of choroidal neovascularisation.
The aim of this paper is to describe various diode laser modifications and their use in treating choroidal neovascularisation in age-related macular degeneration. Diode lasers are used to treat selected choroidal neovascular membranes. Alterations in microprocessor connectivity, and parameters such as maximum spot size, light delivery time and coupled Joule meter, were made so that ophthalmic surgeons could specify treatment possibilities. A trimodal (photocoagulation, transpupillary thermotherapy and photodynamic therapy) application laser device coupled to a single light source has been developed. The new diode laser modifications were technically successful. Microprocessor connectivity was obtained, larger spot sizes were achieved, light delivery time could be extended and energy parameters were available at the display.
