Nd:YAG Laser Vitreolysis for Symptomatic Vitreous Floaters

"A Karickoff lens with goniosol will be used to perform the YAG vitreolysis. The number of shots will be determined at the discretion of the treating physician. A focus offset may be used at investigator discretion. Single shot mode will be used. The maximum energy per pulse will be 7 mJ. The endpoint of treatment is the vaporization of the Weiss ring into gas, as well as the disruption of it into smaller fragments as well as any other vitreous opacities deemed visually significant by the treating physician.~Sham laser treatment will be applied under the same procedure used for laser treatment but by turning the laser power down to 0.3 mJ and using a separate lens covered by a filter that absorbs the power, so no laser enters the eye."
