The Alex Ta2 Eraser is a flashlamp Q-switched solid state laser producing a broadband wavelength of 755 ±25nm.

The provided text is a 510(k) summary for the Alex Ta2 Eraser, a medical laser system. Upon review, it explicitly states "Nonclinical Performance Data: None provided at this time" and "Clinical Performance Data: None provided at this time."

Therefore, based on the provided document:

1. A table of acceptance criteria and the reported device performance: No acceptance criteria or reported device performance are provided as no clinical or nonclinical performance data was submitted. The device was deemed substantially equivalent to a predicate device without this data.
2. Sample sized used for the test set and the data provenance: Not applicable, no test set was used as no performance data was provided.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts: Not applicable, no test set was used.
4. Adjudication method for the test set: Not applicable, no test set was used.
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, no studies were done. The device is a laser system, not an AI-assisted diagnostic tool.
6. If a standalone (i.e. algorithm only without human-in-the loop performance) was done: Not applicable, no performance studies were done. The device is a laser system, not an algorithm.
7. The type of ground truth used (expert concensus, pathology, outcomes data, etc): Not applicable, no performance studies were done.
8. The sample size for the training set: Not applicable, no performance studies were done. The device is a laser system, not an AI/ML algorithm requiring a training set.
9. How the ground truth for the training set was established: Not applicable, no performance studies were done and no training set for an algorithm was needed.
