BOSTON EQUALENS (itafluorofocon A) and EQUALENS II (oprifocon A) RGP Contact Lenses are indicated for daily wear for the correction of refractive ametropia (myopia, hyperopia, astigmatism and presbyopia) in aphakic and not-aphakic persons with nondiseased eyes. The lens may be disinfected using a chemical disinfecting system only.
BOSTON EQUALENS (itafluorofocon A) and EQUALENS II (oprifocon A) Contact Lenses are composed of fluoro silicone acrylate copolymers wet shipped in Boston Advance Comfort Formula Conditioning Solution and stored for up to 30 days.
Here's an analysis of the provided text regarding the acceptance criteria and supporting study for the BOSTON® EQUALENS® and BOSTON® EQUALENS® II RGP Contact Lenses:
The information provided is a 510(k) summary for RGP contact lenses, focusing on the stability of the lenses when wet-shipped and stored in a specific conditioning solution. This type of submission is for demonstrating substantial equivalence to a predicate device, rather than proving novel effectiveness. Therefore, the studies described are primarily performance and safety tests, not clinical efficacy trials in the typical sense for a new drug or high-risk device.
1. Table of Acceptance Criteria and Reported Device Performance
| Test Type | Acceptance Criteria | Reported Device Performance |
|---|---|---|
| Stability/Compatibility (Physical) | Average changes for diameter, base curve, and power compared to DRAFT ISO/CD 8321-2: Optics and Optical Instruments – Contact Lenses - Part 1: Specifications for rigid corneal and scleral contact lenses. | After soaking for thirty days, the silicone acrylate and fluoro silicone acrylate rigid gas permeable contact lenses were determined to be physically compatible with Boston Advance Comfort Formula Conditioning Solution. |
| Microbiology (Bioburden) | 100 Colony Forming Units (CFU) per lens | Less than 10 Colony Forming Units (CFU) per lens (for both control and stored lenses). |
2. Sample Size Used for the Test Set and Data Provenance
- Stability/Compatibility Test Set: The sample size is not explicitly stated. The text refers to "Silicone acrylate (SA) and fluorosilicone acrylate (FSA) tinted rigid gas permeable contact lenses" being subjected to the test.
- Microbiology Test Set: The sample size is not explicitly stated, but it refers to "a set of test lenses" and "two sets of lenses" (one control, one stored).
- Data Provenance: The studies were performed by "The applicant," Polymer Technology. The location of the testing is not specified, nor is whether the data is retrospective or prospective. Given the nature of a 510(k) submission for device approval, these would be prospective tests conducted specifically for the submission.
3. Number of Experts Used to Establish the Ground Truth for the Test Set and Qualifications of Those Experts
This information is not provided in the document. For these types of physical and microbiological performance tests, the "ground truth" is typically established by laboratory measurements against defined standards or protocols, rather than expert consensus on individual cases.
4. Adjudication Method for the Test Set
This information is not applicable and therefore not provided. The tests described are objective laboratory measurements, not subjective evaluations requiring adjudication.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done
No, a Multi-Reader Multi-Case (MRMC) comparative effectiveness study was not done. This type of study is typically used for diagnostic devices where human readers interpret medical images or data, and the goal is to assess the impact of an AI algorithm on human reading performance. The described studies are physical and microbiological performance tests for contact lenses.
6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Was Done
This question is not applicable in the context of this device. A standalone algorithm performance study refers to the evaluation of an AI algorithm's performance without any human intervention. The device in question is a contact lens, and the studies performed are physical and microbiological tests, not AI algorithm evaluations.

- Sample Size (Clinical Study): 212 eyes (106 patients). 36 eyes (18 patients) were non-dispensed.
- Data Provenance: The document does not explicitly state the country of origin, but the submission is to the U.S. FDA, and it mentions "laboratory animals" for acute ocular irritation, implying controlled laboratory and clinical studies rather than retrospective review of existing data. The clinical study was performed by "7 Investigators", which suggests a multi-site clinical trial. It is a prospective study.
3. Number of experts used to establish the ground truth for the test set and the qualifications of those experts
- Not Applicable. This submission is for a contact lens care solution, which does not involve "ground truth" derived from expert image interpretation or similar diagnostic tasks. The "ground truth" for preclinical and clinical studies is based on established laboratory testing methodologies and clinical observations by investigators (e.g., absence of irritation, meeting microbial reduction standards, no clinically significant differences).
4. Adjudication method for the test set
- Not Applicable. As there is no "ground truth" established by experts in the sense of diagnostic interpretation, there is no need for an adjudication method. Clinical data was analyzed using "descriptive statistics, tests for normality, analysis of variance and/or t-tests where appropriate."
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 type of study relates to AI in diagnostic imaging or similar scenarios requiring human reader interpretation, which is not relevant for a contact lens conditioning solution.
6. If a standalone (i.e. algorithm only without human-in-the-loop performance) was done
- Not Applicable. There is no AI algorithm being evaluated in this submission.
7. The type of ground truth used (expert consensus, pathology, outcomes data, etc.)
- Preclinical Studies: The "ground truth" for the preclinical tests (cytotoxicity, ocular irritation, preservative effectiveness, disinfection efficacy, solution compatibility, wetting angle) is derived from the results of standardized laboratory tests and measurements against predefined regulatory or international standards (e.g., USP XXII, 510(k) Guidance Document for Contact Lens Care Products, ISO Draft Standard, ISO specifications for RGP lenses).
- Clinical Study: The "ground truth" (or outcome measure for equivalence) for the clinical study was based on observed clinical safety and efficacy parameters in human subjects, evaluated against the performance of the predicate device, with the goal of demonstrating 'no clinically significant differences'.
8. The sample size for the training set
- Not Applicable. There is no AI algorithm and therefore no "training set" in the context of this submission. The "training" for the product refers to its formulation and testing to meet intended performance.
9. How the ground truth for the training set was established
- Not Applicable. As there is no training set for an AI algorithm, this question is not applicable.
