The Volk PDT Laser Lens has been specifically designed to deliver the maximum laser spot size onto the retina during photodynamic therapy. The Volk PDT Laser Lens delivers the optimum combination of field (137° FOV) and magnification (1.5x) - factors that were carefully chosen after consultation with Dr. Peter K. Kaiser of the Cole Eye Institute. The 1.5x laser spot magnification allows treatment of choroidal neovascular membranes up to the maximum spot size allowed in the trials (6400µm) while providing excellent visualization of the choroidal neovascular membrane. The Volk PDT lens comes standard with SupraCoat which covers the 689nm laser wavelength indicated in this type of procedure. Developed with Peter K. Kaiser, MD.
