There are four selected wavelengths (532nm, 577nm, 670nm, 810nm) in TruScan Pro Laser Console integrated with single/multi spots of TruScan module integrated with slitlamp or single spot of LIO or endo ocular probes.
The 532nm and 810nm laser wavelengths are intended to be used for:
• Pan-retinal photocoagulation for proliferative diabetic retinopathy- with Slitlamp or Endoprobe
• Laser retinopexy for retinal tear and detachments - with Slitlamp or Endoprobe
• Focal or grid photocoagulation for clinically significant macular edema (CSME)- with Slitlamp
• Focal photocoagulation for choroidal neovascularization (CNV) including but not limited to CNV in the setting of wet age-related macular degeneration (wet AMD)- with Slitlamp
• Trabeculoplasty for primary open angle glaucoma (POAG)- with Slitlamp
The 577nm laser wavelength is in the treatment of ocular pathology in the posterior segment; Retinal photocoagulation, panretinal photocoagulation, focal photocoagulation and grid photocoagulation for vascular and structure abnormalities of the retina and choroid including:
• Proliferative and Severe and very severe nonproliferative diabetic retinopathy
• Clinically Significant Macular edema
• Choroidal neovascularization
• Branch and central retinal vein occlusion
• The treatment of choroidal neovascularization associated with wet age-related macular degeneration
• Lattice degeneration
• Retinal tears and detachments
The 670 nm laser wavelength is indicated for retinal and pan-retinal photocoagulation.
Indications for use as stated in the FDA summary.
