Intended Use

The R:GEN is indicated for use by an ophthalmic physician to produce a wound to the Retinal Pigmented Epithelium (RPE) of the retina of the eye, via focal laser treatment of Clinically Significant Macular Edema (CSME).

Device Story

R:GEN is a surgical laser system for focal laser treatment (selective retinal therapy) of retinal diseases; specifically CSME. System components include main body, LCD monitor, slit lamp set, footswitch, and Real Time Feedback (RTF) contact lens. Device uses Q-switched Nd:YLF laser (527 nm) to wound RPE cells. Physician operates system via slit lamp delivery; laser beam passes through RTF contact lens to retina. RTF sensor provides feedback during procedure. Device offers multiple laser patterns (single, square, circle, 2x2 combo) to improve treatment precision. Output is controlled laser energy (0.03-0.35 mJ) limited to 15 pulses per session. Benefits include targeted RPE treatment while minimizing collateral damage to surrounding retinal tissue.

Clinical Evidence

Evidence includes published clinical performance testing confirming device efficacy for CSME treatment. Supporting data includes animal studies demonstrating RPE cell wounding and safety. Bench testing covers biocompatibility (ISO 10993), sterilization (ISO 11135), software V&V (IEC 62304), and electrical/laser safety (IEC 60601-2-22, IEC 60825-1).

Technological Characteristics

Q-switched Nd:YLF laser; 527 nm wavelength; 1.7 µs pulse duration; 0.03-0.35 mJ energy. Delivery via slit lamp adapter with optical fiber and RTF contact lens. Connectivity: Footswitch, LCD touchscreen. Power: 100-240V, 50/60 Hz. Software: Major level of concern. Sterilization: RTF sensor validated per ISO 11135.

## DEVICE DESCRIPTION

The R:GEN is a surgical laser system for use by ophthalmic physicians for performing focal laser treatment, also referred to as selective retinal therapy for the treatment of various retinal diseases by wounding Retinal Pigmented Epithelium (RPE) cells. It is the product of continual technological evolution of the R:GEN technology described in the predicate device (K153769). It consists of the following main components: Main Body, LCD Monitor, Slit Lamp Set, Footswitch, and Real Time Feedback (RTF) Contact Lens which consists of the RTF Body (Real Time Feedback Body) and RTF Sensor (Real Time Feedback Sensor). The Main Body allows the proper operation of the entire system. It contains the laser and is attached to the Footswitch and optical fiber. The laser is a Q-switched Nd:YLF (Neodymium-doped Yttrium Lithium Fluoride) laser with an emission wavelength of 527 nm (produced by second-harmonic generation). The integrated software provides all the functions which are necessary to use the device. The Slit Lamp Set contains the laser delivery system. The laser beam emitted through the Slip Lamp Set is transmitted through the RTF Contact Lens (first through the RTF body and then through the RTF Sensor), and finally irradiated to the patient's retina.

## INDICATIONS FOR USE

The R:GEN is indicated for use by an ophthalmic physician to produce a wound to the Retinal Pigmented Epithelium (RPE) of the retina of the eye, via focal laser treatment of Clinically Significant Macular Edema (CSME).

## INTENDED USE

The subject device has the same intended use as the predicate device which is to produce a wound to the Retinal Pigmented Epithelium (RPE) of the retina of the eye.

## COMPARISON OF TECHNOLOGICAL CHARACTERISTICS

The R:GEN that is the subject of this 510(k) employs the same mechanism of action as the predicate device and achieves its intended use with very similar technological characteristics when compared with the legally marketed predicate and reference devices. Differences in technological characteristics, do not raise difference safety or effectiveness questions and data demonstrates that the R:GEN is as safe and effective as the predicate device for the same intended use. The R:GEN is substantially equivalent to the predicate device based on the information summarized here:

The subject device has a similar design and dimensions, and identical materials as the device cleared in K153769.

The differences in technological characteristics from the predicate include using the same laser technology to provide additional treatment patterns and the use of the Real Time Feedback (RTF) Contact Lens. The subject device offers additional laser treatment patterns including single, square, circle and 2x2 Combo while the predicate device provided a single spot treatment pattern.

The maximum laser energy per pulse for the subject device is lower than the predicate device. The predicate device was designed to deliver a single pulse to the patient with no limitations on the number of pulses to be delivered during a treatment session. The subject device delivers a maximum of 15 pulses per treatment.

The R:GEN subject to this 510(k) has undergone testing to ensure the device is as safe and effective as the predicate for the intended use.

## PERFORMANCE DATA

The R:GEN substantially conforms to the performance standards for light emitting products (21 CFR 1040). Bench testing was performed in accordance with IEC 60825-1 Safety of laser products - Part 1: Equipment classification, and requirement and IEC 60601-2-22 Medical electrical equipment - Part 2-22: Particular requirements for basic safety and essential performance of surgical, cosmetic, therapeutic and diagnostic laser equipment.

## Bench Testing

The following tests were performed to demonstrate safety and performance based on current industry standards:

- . Biocompatibility testing of patient contacting material in compliance to ISO 10993-1, ISO 10993-5, and ISO 10993-10
- Sterilization testing and shelf life validation of the RTF Sensor in compliance to ISO . 11737-1, ISO 10993-7, ISO 11135, and ASTM F1980-16

{10}------------------------------------------------

- Software Verification and Validation were conducted in compliance to IEC 60601-1 and ● IEC 62304. 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." The software for this device was considered as a "Major" level of concern, since a failure or latent flaw could indirectly result in death or serious injury of the patient or operator through incorrect or delayed information or through the action of a care provider.
- Electromagnetic Compatibility (EMC) and Electrical Safety testing in compliance to IEC 60601-1, IEC 60601-1-6, IEC 60601-2-22, IEC 60825-1, and IEC/EN 60601-1-2

## Animal Testing

An animal studies were performed with the R:GEN that established that the use of subject device wounds RPE cells. Additional published animal studies showing the safety and effectiveness of the subject were provided.

#### Clinical Evidence

Published clinical performance testing established that the subject device performs as intended in the treatment of CSME.

## CONCLUSION

Based on the testing performed, including biocompatibility, sterilization, shelf life validation, software verification and validation, EMC and electrical safety, bench performance testing, animal testing, and published clinical evidence, it can be concluded that the subject device is able to perform equivalently to the predicate device. The R:GEN has the same indications for use, and technological characteristics, that do not raise different questions of safety and effectiveness and therefore is assessed to be substantially equivalent to the predicate device.
