Intravitreal argon and carbon dioxide laser, and xenon arc photocoagulation in vitreoretinal surgery
- 30 Downloads
Argon laser, carbon dioxide laser, andxenon arc endophotocoagulators have been used intravitreally to produce chorioretinal lesions during the course of the vitrectomy procedure. The advantages and disadvantages of each method of endophotocoagulation are presented. Both the argon laser and the xenon arc have a fiber optic delivery system. The carbon dioxide delivery system has a series ofquartz waveguides transmitted through a miniature articulating arm. The advantages of using a carbon dioxide laser are its dual quality to act as both aphotocoagulator andphototransector, its lack of pigment dependence, and its ability to deposit its energy in a well-defined area without adverse effects on neighboring ocular tissue.
