Intended Use

VISULAS green is intended for use in photocoagulation of tissues in the posterior and anterior segments of the eye including trabeculoplasty and iridotomy.

Device Story

VISULAS green is a 532 nm frequency-doubled solid-state ophthalmic laser system. It delivers thermal energy to ocular tissue via single-spot or multi-spot modes to perform photocoagulation. The system comprises a laser console, touch control panel, foot switch, instrument table, and various applicators (laser slit lamp, laser indirect ophthalmoscope, endoprobes). Operated by clinicians in clinical settings, the device allows for precise control of laser power (50-1500 mW) and pulse duration (10-2500 ms). The output is used to treat ocular diseases by inducing thermal coagulation. The device provides therapeutic benefits by enabling targeted tissue treatment in the eye.

Clinical Evidence

No clinical data, animal testing, or bench testing were required to establish substantial equivalence. The device relies on software verification and validation testing and compliance with recognized safety standards (ANSI/AAMI ES60601-1, IEC 60601-1-2, ANSI Z80.36, IEC 60825-1, IEC 60601-2-22, IEC 62133).

Technological Characteristics

532 nm frequency-doubled solid-state laser; 50-1500 mW power; 10-2500 ms pulse duration; 50-1000 μm spot size. Includes laser console, touch control panel, foot switch, and applicators (LSL, VISULINK 532/U, Endoprobes, LIO).

### Table 1. Technological characteristics comparison table of VISULAS green and VISULAS 532s

{6}------------------------------------------------

VISULAS green and the predicate device are intended as ophthalmic lasers for photocoagulation. The indications for use are within the same intended use as the predicate device and do not raise different questions of safety and effectiveness.

VISULAS green and the predicate laser system have minor parameter differences but share the same fundamental principle of operation:

Photocoagulation: Continuous wave operation in which thermal energy created by the absorption of the laser energy by ocular tissue causes coagulation.

VISULAS green is substantially equivalent to the predicate laser system presented in the 510(k) premarket notification with respect to indications for use and technological characteristics. Differences between the subject device and the predicate device do not raise any new issues of safety or effectiveness.

### 7. PERFORMANCE DATA

# Biocompatibility Testing

The materials and manufacturing of the subject device is identical to the predicate device and currently marketed devices. Therefore, no new biocompatibility testing is needed for this device.

# Laser safety, electrical safety and electromagnetic compatibility (EMC)

VISULAS green was evaluated against the following requirements and was found to comply with:

- ANSI/AAMI ES60601-1:2005/(R) 2012 ●
- IEC 60601-1-2:2014 ●
- ANSI Z80.36:2016 ●
- . IEC 60825-1:2007
- IEC 60601-2-22:2012
- IEC 62133: 2012 ●

# Software Verification and Validation Testing

The software of this device is considered as a "Major" level of concern. Software verification and validation testing was conducted, and documentation was provided as recommended by FDA's Guidance for Industry and FDA Staff, "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices." Verification and validation of VISULAS green demonstrated that the product works as designed.

# Bench Testing

Not Applicable. Bench testing was not necessary to establish the substantial equivalence of this device.

{7}------------------------------------------------

# Animal Testing

Not applicable. Animal studies are not necessary to establish the substantial equivalence of this device.

# Clinical Data

Not applicable. Clinical studies are not necessary to establish the substantial equivalence of this device.

### CONCLUSION 8.

The VISULAS green is substantially equivalent to the predicate device, VISULAS 532s (K100035).

The VISULAS green is similar in technological characteristics, performance, principles of operation (photocoagulation) and has similar indications for use as the predicate device. Any differences between the proposed device and the predicate device do not raise any new issues of safety or effectiveness. Thus VISULAS green is substantially equivalent to the predicate device.
