Intended Use

The Nuvolase 532 Laser System for Ophthalmology is intended for use in retinal and macular photocoagulation and trabeculoplasty.

Device Story

Nuvolase 532 is a continuous-wave frequency-doubled diode-pumped Nd:YAG laser system. It uses 808 nm diodes to pump an Nd:YAG crystal, producing 1064 nm light, which is frequency-doubled to 532 nm green laser light. An electro-mechanical shutter controls exposure durations (0.05 to 1.0 seconds or continuous). The system includes a 670 nm red diode aiming beam. The device is used by ophthalmologists in clinical settings for retinal/macular photocoagulation and trabeculoplasty. The laser beam is delivered via fiber optic and laser slit lamp. The output provides therapeutic thermal energy to ocular tissues to treat specific retinal or macular conditions or to perform trabeculoplasty. The physician uses the slit lamp delivery system to visualize the target tissue and apply the laser energy, affecting clinical decision-making by enabling precise photocoagulation or trabecular meshwork modification.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Continuous-wave frequency-doubled diode-pumped Nd:YAG laser; 532 nm therapeutic wavelength; 670 nm red diode aiming beam; 50 mW to 1.5 W (up to 2.0 W) power output; electro-mechanical shuttering; fiber optic and slit lamp delivery; standalone system.

Indications for Use

Indicated for retinal and macular photocoagulation and trabeculoplasty in patients requiring ophthalmic laser treatment.

Regulatory Classification

Identification

(1) A carbon dioxide laser for use in general surgery and in dermatology is a laser device intended to cut, destroy, or remove tissue by light energy emitted by carbon dioxide.(2) An argon laser for use in dermatology is a laser device intended to destroy or coagulate tissue by light energy emitted by argon.

# Summary of Safety and Effectiveness

### Regulatory Authority:

Safe Medical Devices Act of 1990, 21 CFR 807.92

#### Name of Device:

Trade Name: Nuvolase 532 Laser System for Opthalmology

Common Name: Ophthalmic Laser Photocoagulator

Classification Name: Ophthalmic Laser (per 21 CFR 886.4930)

#### Predicate Devices:

The Nuvolase 532 Laser System for Opthalmology has been modified from the American Laser Medical, Inc. Nuvolase 660 Laser System for Ophthalmology, K972561.

## Description of Device:

The Nuvolase 532 Laser System for Ophthalmology is a continuous-wave frequency-doubled diode-pumped Nd:YAG laser system. Treatement beam power output for the system is 50 milliwatts to 1.5 watts at a wavelength of 532 nm. Depending on the delivery device efficiency, the maximum power level may be as much as 2.0 Watts CW. The aiming beam is provided by a red diode laser operating at 670 nm. Exposure durations for the Nuvolase 532 Laser System for Ophthalmology (in seconds) are 0.05, 0.1, 0.25, 0.5, 1.0, and continuous. Delivery of the beam occurs via fiber optic and laser slit lamp.

#### Intended Use:

The Nuvolase 532 Laser System for Ophthalmology is intended for use in retinal and macular photocoagulation and trabeculoplasty.

## Technological Characteristics/Device Comparison:

The Nuvolase 532 Laser Sysem is a modification of the Nuvolase 660 Laser System for Ophthalmology, already in legal commercial distribution. Each of the systems optically pumps an Nd: Y AG crystal using 808 nm diodes to produce laser light at 1064 nm. This light passes through a second crystal which exhibits a non-linear optical response, re-emitting the laser energy at the first harmonic of the 1064 line, 532 nm greeen. The continuous wave beam is then shuttered electro-mechanically to produce the desired exposure durations. Each device is intended for retinal and macular photocoagulation and trabeculoplasty. The delivery system is the same in each case.

### Conclusion:

The device modification does not affect the indications for use, materials, method of manufacture, or technology of the legally marketed device.

Dear Mr. Hoefer:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to 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). You may, therefore, market the device, subject to the general controls provisions of the Act. 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.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the current Good Manufacturing Practice requirement, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic (QS) inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
