Based on the provided FDA 510(k) summary for the Phototherapy System (OL-PDT950) (K230342), here's an analysis of the acceptance criteria and the study proving the device meets them:
Important Note: This document is a 510(k) summary for a premarket notification, which demonstrates substantial equivalence to existing devices. It is not a clinical study report that would typically detail the comprehensive acceptance criteria and performance data for a novel device or a device requiring de novo classification. Therefore, the information related to clinical performance is limited, and many of the requested items (e.g., sample size for test set, expert qualifications, MRMC study, ground truth establishment) are generally not part of a 510(k) submission for this type of device.
Acceptance Criteria and Device Performance for Phototherapy System (OL-PDT950)
The device, a Phototherapy System, is intended to emit energy to treat dermatological conditions using red, blue, and infrared light. For a 510(k) submission of this nature, the "acceptance criteria" are primarily based on demonstrating substantial equivalence to existing legally marketed predicate devices. This is achieved through a comparison of technological characteristics and performance specifications. Clinical efficacy is typically established through a combination of the predicate device's history of safe and effective use and non-clinical performance testing of the new device.
The study proving the device meets acceptance criteria is primarily composed of non-clinical tests and a comparison of technical specifications to predicate devices. Clinical testing was not performed for this specific submission as stated in Section 6.1.

2. Sample size used for the test set and the data provenance
- Sample Size for Test Set: Not applicable for clinical data, as stated in Section 6.1: "Clinical testing was not performed for the subject device as part of the submission."
- Data Provenance: The reported performance data for the subject device comes from non-clinical tests (e.g., electrical safety, electromagnetic compatibility, photobiological safety, and performance specifications adherence). The location of these tests is not explicitly stated but can be inferred to be China, given the manufacturer's location (Shanghai, China). The data is inherently prospective in terms of the specific device's specifications and test results.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Not applicable. As clinical testing was not performed, there was no "ground truth" derived from expert consensus on medical conditions for a test set. Normative data for device specifications and compliance with standards are established through engineering and testing professionals, not medical experts.
4. Adjudication method for the test set
- Not applicable. There was no clinical test set requiring adjudication.
5. If a multi-reader multi-case (MRMC) comparative effectiveness study was done, If so, what was the effect size of how much human readers improve with AI vs without AI assistance
- Not applicable. This device is a phototherapy system, not an AI-powered diagnostic or assistive tool for human readers (like radiologists interpreting images). Therefore, an MRMC study is irrelevant.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done
- Not applicable. This is not an algorithmic device. Its performance is based on its physical light emission characteristics.
7. The type of ground truth used
- For the non-clinical tests and technical specifications, the "ground truth" is established through objective measurements (e.g., power meters for irradiance, spectrophotometers for wavelength verification) and compliance with internationally recognized consensus standards (IEC 60601-1, IEC 60601-1-2, IEC 60601-2-57, IEC 62471). There is no "pathology" or "outcomes data" ground truth used for this type of 510(k) submission.
8. The sample size for the training set
- Not applicable. This device is not an AI/machine learning algorithm, so there is no concept of a "training set."
9. How the ground truth for the training set was established
- Not applicable. As there is no training set for this device.

- · The removal of unwanted hair to effect stable long-term or permanent hair reduction.
- · For use on Fitzpatrick skin types (I-V)
- Permanent hair reduction is defined as the long-term, stable reduction in the number of hairs regrowing when measured at 6, 9, and 12 months after the completion of a treatment regime.
The IPL System - KDT750 is a multi-wavelength non-invasive system for IPL skin treatments, treatment of vascular and pigmented lesions, and hair removal using two wavelength ranges: 530-950nm and 640-950nm. The IPL System consists of a system console, electronics and software, cooling system, and two hand pieces with different wavelength.
The provided text is a 510(k) summary for the IPL System - KDT750, a non-AI medical device (an IPL system for aesthetic applications). Therefore, the information requested about acceptance criteria and studies that prove the device meets these criteria, specifically in the context of an AI/ML device, is not applicable.
The document discusses the substantial equivalence of the IPL System - KDT750 to a predicate device (Alma Harmony XL Multi-Application Platform) based on general device performance characteristics, safety, and non-clinical tests. It explicitly states that clinical testing was not performed for this submission.
Here's why the requested information cannot be extracted from this document:
- No AI Component: The device is an "IPL System," which is a light-based medical device. There is no mention of an AI/ML component.
- No Acceptance Criteria for AI Performance: Since it's not an AI device, there are no acceptance criteria related to AI performance metrics like sensitivity, specificity, accuracy, etc.
- No Clinical Study for Performance Proof: The document clearly states: "Clinical testing was not performed for the subject device as part of the submission." This means there is no study described here to "prove the device meets the acceptance criteria" in a clinical performance sense.
- No Ground Truth Establishment: Without clinical performance testing, there's no need for ground truth establishment, expert consensus, or adjudication methods as typically required for AI/ML device validation.
- No Training/Test Sets: The concepts of training and test sets are specific to AI/ML model development and validation, which are not relevant to this device.
- No MRMC Study: A Multi-Reader Multi-Case (MRMC) study is used to assess the impact of an AI system on human reader performance, which again is irrelevant for a non-AI device.
In summary, the provided document is a regulatory submission for a traditional medical device (IPL system) demonstrating substantial equivalence based on technological characteristics and non-clinical safety testing, not an AI/ML device demonstrating performance through clinical studies with specific acceptance criteria.
If you have a document pertaining to an AI/ML medical device, I would be happy to analyze it for the requested information.
