Intended Use

LMNT O2 is an over-the-counter device indicated to emit energy in the red and IR region of the spectrum for use in dermatology for the treatment of periorbital wrinkles. In addition, LMNT O2 indicated to emit energy in the blue region of the spectrum for use in dermatology for the treatment of mild to moderate acne.

Device Description

LMNT O2 is a hand held device that uses low power light spectrum at red and infrared LED, at wavelength of 633 ±15nm, 830 ±15nm distribution with no hot spots for the treatment of periorbital wrinkles. The device also uses blue LED, at wavelength of 415 ±15nm emitting optical power in a uniform distribution with no hot spots for the treatment of acne.Designed for home-use.

AI/ML Overview

Please note: The provided FDA 510(k) clearance letter and summary discuss a device for dermatological treatment of wrinkles and acne, which is not related to AI/ML or diagnostic imaging as typically implied by "acceptance criteria" and "ground truth" in the context of advanced AI medical devices. The document details non-clinical testing for electrical safety, EMC, biocompatibility, and physical performance parameters of a light-based therapy device.

Therefore, a significant portion of your requested information (e.g., MRMC study, human reader improvement with AI, number of experts for ground truth, adjudication methods, training/test set data provenance, sample size for training and testing AI models) cannot be extracted from this document because the device is a physical therapy device, not an AI/ML diagnostic or assistive tool.

However, I will extract and present the relevant information about the acceptance criteria and performance as much as possible, focusing on the available physical and performance testing data.

Acceptance Criteria and Device Performance (Based on provided document)

The acceptance criteria for the LMNT O2 device are primarily met through performance testing related to its physical outputs and safety standards. The document doesn't present a table of "acceptance criteria" vs. "reported device performance" in the typical AI/ML sense (e.g., sensitivity, specificity, AUC). Instead, it states conformity to international consensus standards and specific physical measurements.

Here's an interpretation based on the provided text:

2. Sample Size for Test Set and Data Provenance

This information is not applicable or available from the provided document as the device is a light therapy device, not an AI/ML algorithm requiring a data-based test set in the conventional sense. The "testing" refers to non-clinical bench testing of the physical properties and safety.

3. Number of Experts and Qualifications for Ground Truth

This information is not applicable or available. Ground truth, in the context of AI/ML, refers to clinically validated diagnoses or measurements against which an algorithm's performance is compared. For this physical device, "ground truth" is established by adhering to recognized international engineering and safety standards.

4. Adjudication Method for the Test Set

This information is not applicable or available. Adjudication methods are typically used in clinical studies or AI/ML ground truth establishment to resolve discrepancies among expert readers.

5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study was done

No. An MRMC study is relevant for comparing diagnostic performance, often with and without AI assistance, or comparing different diagnostic methods. This device is a therapeutic light device, and the clearance is based on its physical properties and safety, demonstrating substantial equivalence to predicates, not a diagnostic performance comparison.

6. If a Standalone (i.e. algorithm only without human-in-the loop performance) was done

This information is not applicable or available. The device is a standalone physical product, not a diagnostic algorithm.

7. The Type of Ground Truth Used

The "ground truth" for this device's performance validation is based on engineering standards, physical measurements, and safety compliance. This includes:

  • Conformity to international consensus standards (e.g., IEC 60601 series, ISO 10993 series, IEC 62471).
  • Bench testing results for specific physical characteristics (e.g., LED wavelengths, energy density, skin temperature, hot spots).
  • Demonstration of substantial equivalence to legally marketed predicate devices with established safety and efficacy profiles for similar indications.

8. The Sample Size for the Training Set

This information is not applicable or available. The device is not an AI/ML algorithm that is "trained" on a dataset.

9. How the Ground Truth for the Training Set was Established

This information is not applicable or available. As stated above, there is no AI/ML training set for this device.
