Intended Use

Luminopia is a software-only digital therapeutic designed to be used with commercially available Head-Mounted Displays (HMDs) which are compatible with the software application. Luminopia is indicated for improvement in visual acuity in amblyopia patients, aged 4 to <13, associated with anisometropia and/or with mild strabismus, having received treatment instructions (frequency and duration) as prescribed by a trained eye-care professional. Luminopia One is intended for both previously treated and untreated patients. Luminopia is intended to be used as an adjunct to full-time refractive correction, such as glasses, which should also be worn under the HMD during Luminopia therapy. Luminopia is intended for prescription use only, in an at-home environment.

Device Story

Luminopia is a software-only digital therapeutic (SaMD) for pediatric amblyopia. It operates on off-the-shelf head-mounted displays (HMDs) requiring Wi-Fi. The device consists of a Video Content Platform and Therapeutic Algorithms. Patients select TV shows or movies; the software modifies the video input to each eye via contrast reduction and dichoptic masks to break interocular suppression and encourage amblyopic eye usage. The HMD provides a stereoscopic viewing experience. Used at home under clinician prescription, the device aims to improve visual acuity. It functions as an adjunct to refractive correction (glasses).

Clinical Evidence

Prospective real-world registry study (N=290, aged 4 to <13) evaluated BCVA improvement. Patients used Luminopia for average 8.2 months. Mean BCVA improved 1.1 lines (95% CI: 0.92-1.3). Subgroup analysis: 4-7 years (N=186) improved 1.2 lines; 8-12 years (N=104) improved 0.95 lines. Adverse events were low (3% overall), consistent with prior clinical data (DEN210005).

Technological Characteristics

SaMD mobile application; two software units (Video Content Platform, Therapeutic Algorithms). Operates on off-the-shelf HMDs (minimum requirements: ≥60Hz refresh, ≥48 cd/m2 luminance, ≥90% Michelson contrast). Dichoptic presentation principle. No hardware modifications. Wi-Fi connectivity required.

Indications for Use

Indicated for improvement in visual acuity in amblyopia patients, aged 4 to <13, with anisometropia and/or mild strabismus. Intended as an adjunct to full-time refractive correction for both previously treated and untreated patients. Prescription use only in home environment.

Classification Name: Digital Therapy Device for Amblyopia (21 CFR 886.5500, Product Code: QQU)
Predicate Device: Luminopia (Submission Number: K233720)

Indications for Use: Luminopia is a software-only digital therapeutic designed to be used with commercially available Head-Mounted Displays (HMDs) which are compatible with the software application. Luminopia is indicated for improvement in visual acuity in amblyopia patients, aged 4 to &lt;13, associated with anisometropia and/or with mild strabismus, having received treatment instructions (frequency and duration) as prescribed by a trained eye-care professional. Luminopia is intended for both previously treated and untreated patients. Luminopia is intended to be used as an adjunct to full-time refractive correction, such as glasses, which should also be worn under the HMD during Luminopia therapy. Luminopia is intended for prescription use only, in an at-home environment.

## Device Description:

Luminopia is Software as a Medical Device (SaMD) Mobile Application that is intended to improve vision in pediatric patients with amblyopia. The Mobile Application ("Mobile App") consists of two software units: the Video Content Platform and the Therapeutic Algorithms. The Video Content Platform allows the Patient to browse from a library of popular TV shows and movies and select videos to watch. The Video Content Platform, without the Therapeutic Algorithms, is analogous to consumer video applications (e.g., YouTube, Netflix). The Therapeutic Algorithms provide the actual treatment, by applying modifications to the videos shown by the Video Content Platform.

It is hypothesized that the Therapeutic Algorithms improve vision by breaking interocular suppression and encouraging amblyopic eye usage. The Therapeutic Algorithms are applied to patient-selected video content in the same manner for every video. The algorithms reduce contrast to the stronger eye's input to break interocular suppression and encourage amblyopic eye usage. Additionally, parts of each eye's input are occluded by dichoptic masks superimposed over the video content to promote binocular combination. The masks rotate through predefined pairs over the course of treatment.

K243819

The Mobile App is designed to be used with commercially available, off-the-shelf head-mounted displays ("HMDs") and does not require any hardware modifications or customization. These HMDs can either consist of a headset combined with a display unit or consist of an all-in-one unit. The HMD serves two functions. Firstly, the HMD serves as the computing platform for the Mobile App, analogous to a smartphone for a mobile medical application. The HMD requires a Wi-Fi connection to run the Mobile App. Secondly, the HMD serves as a viewing device for dichoptic presentation of the content in the app, similar to a stereoscope device (FDA Product Code: HJR). During usage, the Mobile App displays a separate image to each of the Patient's eyes within the HMD, and the images appear as one when viewed together.

All compatible HMDs meet the following set of minimum requirements:

| Parameter | HMD |
| --- | --- |
| Luminance and luminance uniformity | ≥ 48 cd/m2 |
| Michelson contrast (low spatial frequency) | ≥ 90% across field of view |
| Michelson contrast (high spatial frequency grille pattern) | Baseline requirement |

## Performance Data:

### Clinical Performance Evaluation

The safety and efficacy of Luminopia for 4 to &lt;8-year-old patients with amblyopia was established in DEN210005. This Clinical Performance Evaluation describes effectiveness of Luminopia in improving vision in children aged 4 to &lt;13 in a real-world study in accordance with FDA Guidance: Use of Real-World Evidence to Support Regulatory Decision-Making for Medical Devices.

Luminopia was evaluated in a Real-World Registry study, designed prospectively, which collected retrospective data from medical health records of patients treated with Luminopia under usual care. The registry employed an all-comers design and included any patient with an

amblyopia diagnosis and Luminopia use of at least 12 weeks, and only excluded patients who had taken part in past Luminopia clinical trials. Visual Acuity change from the time of Luminopia prescription to the last visit in the registry study was reported. The registry included 334 patients, of whom 290 were aged 4 to $&lt; 13$ with a diagnosis of amblyopia associated with anisometropia and/or strabismus.

The registry study patients had an average of 2.8 years in refractive correction and 1.8 years using patching and/or atropine before starting Luminopia. Patients used Luminopia treatment for an average of approximately 8.2 months. Across all patients aged 4 to $&lt; 13$ with a diagnosis of amblyopia associated with anisometropia and/or strabismus, the mean amblyopic eye best-corrected visual acuity (BCVA) improved 1.1 lines (95% CI: 0.92-1.3 lines, N=290). For the subgroup of patients aged 4-7, the mean amblyopic eye best-corrected visual acuity (BCVA) improved 1.2 lines (95% CI: 1.0-1.4 lines, N=186). For the subgroup of patients aged 8-12, the mean amblyopic eye best-corrected visual acuity (BCVA) improved 0.95 lines (95% CI: 0.66-1.3 lines, N=104).

The Adverse Event risk profile of Luminopia has been established through DEN210005. The risks of Luminopia reported through real-world data is lower than the risk reported within the RCT, with only 9 (3%, N=290) non-serious adverse events reported, although this is likely due to underreporting in the real-world environment. The risk of Luminopia in 4-12-year-olds is expected to be similar to the risk for 4-7-year-olds, as established in DEN210005.

## Conclusion:

As described in this 510(k) Summary, the subject and predicate devices have the same intended use and similar indications for use. There are no differences in technological characteristics between the subject and predicate devices. Clinical performance data from a real-world registry study in addition to the clinical evidence established in DEN210005 of the same device are sufficient to establish the safety and effectiveness of the subject device when used in accordance with its proposed labeling.
