IV. Device Description
The Voyager DSLT device is a Q-switched, 532 nm-wavelength, frequency-doubled Nd:YAG laser that is intended for use in performing selective laser trabeculoplasty. The laser spots produced by the Voyager DSLT device have a 400 μm spot size, a 3 ns pulse duration, and a 50-Hz pulse
{5}
repetition rate. The sequence of laser spots consists of 120 spots in a predefined circumferential elliptical pattern delivered at a pre-defined pulse energy level. The spots are delivered through the limbus to the trabecular meshwork in a non-contact fashion, without the need for the use of a contact gonioscopy lens. The device automatically locates the treatment location. The treatment location may be adjusted slightly by the operator. Once confirmed by the operator, the device then automatically applies the laser treatment sequence to the limbal region of the eye, while the eye tracker compensates for any eye movement. The default energy setting is $1.8\mathrm{mJ} / \mathrm{pulse}$ .

The software of the Voyager DSLT device was updated to incorporate 3 changes:
1. Addition of the "Complete an Incomplete Treatment" feature: This feature allows the user to complete a procedure that was interrupted and not fully completed.
2. Modifications to the Target Definition screen to remind the user to ensure proper target definition, and to provide options to the user for how the target definition ring is displayed and for editing the target definition.
3. Automatically add results of the test card daily check to the exported treatment record

These changes did not raise new types of questions regarding the safety and effectiveness of the device.
## VII. Summary of Non-Clinical Testing
Based on the risk assessment and design control requirements, the following verification and validation testing/analysis was performed:
- Bench testing was performed to demonstrate the ability of the Voyager DSLT to properly align the target definition ring between the original and new procedure, when completing an incomplete procedure.
- An analysis of the changes on human factors was conducted per FDA guidance, "Applying Human Factors and Usability Engineering to Medical Devices"
- Animal testing, performed to support 510(k) clearance of the predicate Eagle device (K230722), also supports the safety of the added "Complete an Incomplete Treatment" feature.
- Software verification and validation testing: BELKIN developed and verified the software in accordance with a major level of concern described in the FDA "Guidance for the Content of Premarket Submissions for Software Contained in Medical Devices" and also per the IEC 62304: 2015 Medical Device Software - Software Life Cycle Processes standard.
Results of the non-clinical testing support a substantial equivalence determination. The Voyager DSLT device is substantially equivalent to its predicate device for the indications for use.
## VIII. Conclusions
The Voyager DSLT device has the same indications for use as the predicate device. The differences in technological characteristics of the Voyager device do not raise new or different types of questions of safety or effectiveness. The results of the non-clinical performance testing demonstrate that the Voyager DSLT device functions as intended and is substantially equivalent to the predicate device.
