Intended Use

Retinal Photocoagulation . Pan Retinal Photocoagulation . Endophotocoagulation. ● Photocoagulation for Macular Degeneration . . Laser Trabeculoplasty. The intended uses for this product are: Retinal treatments, including; . Retinal Photocoagulation . Pan Retinal Photocoagulation . Endophotocoagulation . These treatments involve the destruction of neovascular complexes, to obliterate areas of microinfarction or capillary closure. Retinal Photocoagulation will be carried out using principally the Slitlamp Delivery System accessory. Pan Retinal Photocoagulation will be carried out using either of the Laser Indirect Ophthalmoscope or the Slitlamp Delivery System accessory. Endophotocoagulation will be carried out using any one of the three variants of the endoprobe accessories, namely Straight, Curved or Aspirating Endooccular Probes. Photocoagulation for Macular Degeneration involves the destruction of leaking vessels in the macular and paramacular region, and ultimately to produce a chorioretinal adhesion that will resist ongoing vitreoretinal traction. This treatment will be carried out using the slitlamp microscope mounted Slitlamp Delivery System accessory. Laser Trabeculoplasty, the photocoagulation of the trabecular meshwork to create apertures and increase the flow of the aqueous humor in order to treat open-angle glaucoma. This treatment will be carried out using the slitlamp microscope mounted Slitlamp Delivery System accessory.

Device Story

Compact, solid-state frequency-doubled Nd:YAG laser photocoagulator (532 nm). Operates in visible green spectrum; delivers laser energy via fiberoptic accessories: slitlamp delivery systems, laser indirect ophthalmoscopes, or endoprobes (straight, curved, aspirating). Used by qualified physicians in clinical settings for ophthalmic procedures. Physician controls energy delivery via software-driven system; aiming beam (635 nm red diode) assists targeting. Device produces chorioretinal adhesion or trabecular meshwork apertures to treat retinal conditions and open-angle glaucoma. Benefits include precise destruction of neovascular complexes and leaking vessels, reducing microinfarction and improving aqueous humor flow.

Clinical Evidence

No clinical data provided. Substantial equivalence is based on technological characteristics and intended use comparisons to legally marketed predicate devices.

Technological Characteristics

Solid-state frequency-doubled Nd:YAG laser; 532 nm wavelength; Class IV laser. Air-cooled diode-pumped configuration. Power output 30 mW to 2 W. Aiming beam: 635 nm red diode (0.05-0.95 mW). Dimensions: 310x510x190 mm; Weight: 17 kg. Electrical: 110/220 VAC, 450 W. Software-driven control system. Fiberoptic delivery accessories.

Indications for Use

Indicated for retinal photocoagulation, pan retinal photocoagulation, endophotocoagulation, photocoagulation for macular degeneration, and laser trabeculoplasty for open-angle glaucoma. Used for destruction of neovascular complexes, microinfarction, capillary closure, leaking vessels, and trabecular meshwork apertures.

Regulatory Classification
