Indications for Use
The Iridex® Laser Console (532 model and 577 model) are solid state lasers that are used to deliver laser energy in either continuous wave pulse (CW-pulse) or MicroPulse® mode, for ophthalmic applications (532 and 577 models) and for Ear. Nose, and Throat (Otolaryngology) applications (532 model only).
Device Story
Solid-state laser consoles (532 nm green or 577 nm yellow) deliver laser energy via fiber optic probes to target tissues. Systems feature footswitch activation, touchscreen/knob interface, and air-cooled design. Used in physician offices, hospitals, and ambulatory surgical centers by clinicians. Operates in continuous wave or MicroPulse modes to perform photocoagulation, ablation, or hemostasis. Output energy is controlled by the clinician to achieve specific therapeutic effects on ocular or ENT tissues. Benefits include precise tissue management and treatment of various retinal and glaucomatous conditions.
Clinical Evidence

Dear Mari Iwamoto, PhD:
We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. Although this letter refers to your product as a device, please be aware that some cleared products may instead be combination products. The 510(k) Premarket Notification Database located at https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfpmn/pmn.cfm identifies combination product submissions. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration. Please note: CDRH does not evaluate information related to contract liability warranties. We remind you, however, that device labeling must be truthful and not misleading.
If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
Please be advised that FDA's issuance of a substantial equivalence determination does not mean that FDA has made a determination that your device complies with other requirements of the Act or any Federal statutes and regulations administered by other Federal agencies.

### Device Description
The Iridex 532/577 Laser consoles are solid state lasers that are used to deliver laser energy in continuous wave and MicroPulse® for ophthalmic applications and (for 532 only) ear, nose, and throat (ENT) / otolaryngology applications. The Iridex® 532 Laser delivers a 532 nm wavelength (green) laser emission, and the Iridex® 577 Laser delivers a 577mm wavelength (true-yellow) laser emission.
The Iridex 532 Laser and the Iridex 577 Laser systems are comprised of a laser console with footswitch and an optical fiber delivery device. Each laser console model contains two laser diodes as follows:
- Iridex 532 Laser: 532 nm for Treatment and 650 nm for Aiming beam ●
- Iridex 577 Laser: 577 nm for Treatment and 650 nm for Aiming beam ●
imaging optics, power supply, control electronics, and software/embedded firmware (with microprocessor). Lasing can only be initiated from the footswitch.
Optical fiber Delivery Devices are provided separately. The following tables shows compatible delivery devices.
