The MB 105 Millennium blade is intended to be used as a replacement blade for the Moria M2 Non-Disposable Microkeratome.
The MB 105 Millennium Blade is a replacement blade designed to be used with the Moria M2 Non Disposable Microkeratome. The MB 105 Millennium Blade is a single-use only, disposable device. The Blade material is similar to that used in predicate devices (stainless steel).
The provided document is a 510(k) Premarket Notification for the Millennium Biomedical Inc. MB 105 Millennium Blades. This type of submission focuses on demonstrating substantial equivalence to a legally marketed predicate device rather than comprehensive clinical studies with detailed acceptance criteria and performance data like those found in a PMA (Premarket Approval) application.
Therefore, the document does not contain the requested information regarding specific acceptance criteria for device performance, or a study proving the device meets said criteria in the way a clinical trial report would.
Here's why and what can be inferred from the document:
- Type of Device: The MB 105 Millennium Blade is a replacement blade for a microkeratome, a Class I device (regulated under 21 CFR 886.4370 as a Keratome). Class I devices typically have lower risk and do not require extensive clinical data for market clearance.
- 510(k) Process: The 510(k) pathway demonstrates that a new device is "substantially equivalent" to a legally marketed predicate device. This often involves comparing device characteristics (design, materials, intended use, performance testing, etc.) rather than conducting de novo clinical trials to establish safety and effectiveness against explicit performance criteria.
- Content of the Document: The summary focuses on:
- Identifying the submitter and device.
- Listing predicate devices.
- Describing basic physical and performance characteristics (blade material is stainless steel, similar to predicates).
- Stating the intended use (replacement blade for a specific microkeratome).
- The FDA's decision letter confirming substantial equivalence.
Therefore, I cannot populate the table or answer the specific questions as the required information is not present in the provided text. The document does not describe:
- A table of acceptance criteria and reported device performance.
- Sample sizes for test sets or data provenance.
- Number/qualifications of experts for ground truth.
- Adjudication methods.
- MRMC studies or effect sizes.
- Standalone algorithm performance.
- Types of ground truth used.
- Sample size for training sets.
- How ground truth for training sets was established.
The absence of this information is typical for a 510(k) submission for a Class I device where substantial equivalence is demonstrated through non-clinical means (e.g., material testing, mechanical testing) rather than extensive clinical efficacy or diagnostic performance studies.

The MB 103 Millennium Blade is a replacement blade designed to be used with the Moria CB Microkeratome. The MB 103 Millennium Blade is a single-use only, disposable device. The Blade material is similar to that used in predicate devices (stainless steel).
Acceptance Criteria and Study for Millennium Biomedical Inc. MB 103 Millennium Blades
Based on the provided document, the MB 103 Millennium Blade is a replacement blade for a microkeratome, not a diagnostic AI device requiring complex performance assessments. The acceptance criteria and supporting "study" are therefore focused on physical and functional equivalence to predicate devices, rather than typical AI performance metrics like sensitivity or specificity.
1. Table of Acceptance Criteria and Reported Device Performance
Given the nature of the device, the "acceptance criteria" are primarily established by demonstrating substantial equivalence to predicate devices in terms of physical characteristics and performance, as presented in the "How the technological characteristics of the device compare to those of the predicate or legally marketed devices" section. The "reported device performance" refers to the results of the field study.
| Acceptance Criteria (Technological Characteristics) | MB 103 Millennium Blade Performance (Reported) |
|---|---|
| Intended Use | As a replacement blade for the Moria CB Microkeratome. |
| Operating Principle | Blade held in keratome head, oscillates by turbine; keratome head adapts to turbine via threaded part; gas-powered turbine motor. |
| Blade Design | Single edge blade with plastic blade holder. |
| Blade Hardness | 52 Rockwell C |
| Sterilization Method | Cobalt 60 radiation |
| Blade Material | Stainless steel |
| Blade Holder Material | Delrin |
| Patient Contact Portion of Device | Blade cutting edge |
| Dimensional Equivalency | Match to predicate (specific measurements not explicitly stated as criteria, but shown to be equivalent). |
| Sharpness Verification | Clinically tested and verified. |
| Overall Performance | Acceptable for intended use; no adverse events reported. |
2. Sample Size Used for the Test Set and Data Provenance
- Sample Size: Not explicitly stated as a number of devices or procedures. The study is referred to as a "market field study," implying real-world usage.
- Data Provenance: The study was "conducted in Korea and China." It is a prospective observational study, as it's a "market field study" assessing performance and adverse events during use.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
This type of information is not applicable and not provided for this device. The "ground truth" here is successful performance in clinical use as a surgical blade, which would be assessed by the performing surgeons during the "market field study." No formal "experts" establishing "ground truth" on individual cases are mentioned in the context of an AI study.
4. Adjudication Method for the Test Set
Adjudication methods (like 2+1, 3+1) are typically relevant for AI studies involving subjective human assessment for ground truth determination. This is not applicable here as the "ground truth" is direct device performance in a surgical context, rather than interpretive diagnostic outcomes.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
No, an MRMC comparative effectiveness study was not done. This type of study assesses how AI assistance impacts human reader performance, which is not relevant for a surgical blade.
6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done
No, a standalone performance study (in the context of an AI algorithm) was not performed. The device is a physical surgical blade, not an algorithm. Its performance is inherently "standalone" in its mechanical function, but evaluated in the context of human surgical use.
7. The Type of Ground Truth Used
The ground truth used was outcomes data and expert observation. The "market field study" essentially assessed the blade's performance in its intended use, with the primary outcome being "acceptable performance" and the absence of "adverse events" as reported by the users (surgeons) in the target markets. "Clinically tested and verified" for sharpness also implies a form of ground truth established by clinical observation of performance.
8. The Sample Size for the Training Set
This concept is not applicable. The device is a physical product, not an AI algorithm that requires a "training set." The design and manufacturing process would involve internal testing and validation, but this is distinct from "training data" for an algorithm.
9. How the Ground Truth for the Training Set Was Established
Not applicable, as there is no "training set" in the AI sense for this device. The design and engineering process established the specifications based on predicate devices and presumably internal quality standards for surgical blades.
