introduction: the aim of the present study was to evaluate the effect of photodynamic therapy in the treatment of experimental corneal neovascularization (nv) with benzoporphyrin derivative (bpd). methods: one group was considered as control (n=6 eyes) then, corneal nv was induced in 30 new zealand male rabbits (n=60 eyes) by placing 7.0 silk sutures at midstromal depth approximately1mm from th...

it is the output power and density of the lasers which determine whether a laser is a low or high-power one. if the density is less than 670mw/cm2, the laser is called a low power one. the output power of these lasers is usually less than 250mw. they use different mechanisms to accelerate wound healing such as: cellular biostimulation, improvement of circulation, vasodilation, analgesic and ant...
