LOBOB UNIVERSAL CONTACT LENS CLEANER by LOBOB LABORATORIES, INC.

The device is currently marketed as a cleaner for rigid gas permeable (RGP) and hard (PMMA) contact lenses. The current notification is for the added indication of cleaning soft (hydrophilic) contact lenses.

AI/ML Overview

The provided text does not contain detailed acceptance criteria for the device's performance, nor does it describe a study specifically designed to prove the device meets such criteria in terms of quantitative measures. The document is a 510(k) summary for a contact lens cleaner, focusing on demonstrating substantial equivalence to a predicate device for an expanded indication (cleaning soft contact lenses).

Here's an analysis based on the available information:

1. Table of Acceptance Criteria and Reported Device Performance:

The document does not explicitly state quantitative acceptance criteria (e.g., specific percentage reduction in protein deposits, a certain level of comfort score, or a defined visual acuity improvement). Therefore, a table with such criteria and corresponding device performance cannot be generated.

The document mentions:

"Non-clinical testing supports the safety and effectiveness of the device from microbiology, toxicology, chemistry and manufacturing perspectives." (No specific criteria or performance data provided.)
"Clinical data were obtained from a multi-center study involving a hydrophilic contact lens consisting of 72 eyes followed for 3 months." (No specific performance outcomes or acceptance criteria for this clinical data are detailed in this summary.)

2. Sample Size Used for the Test Set and Data Provenance:

Test Set Sample Size: 72 eyes.
Data Provenance: The document does not specify the country of origin. It indicates it was obtained from a "multi-center study," suggesting multiple locations, but not specific countries. The study appears to be prospective, as it involved following the 72 eyes for 3 months.

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. The study described is a clinical trial, and the "ground truth" would likely refer to clinical outcomes (e.g., lens cleanliness, adverse events, comfort). The adjudication method for these clinical outcomes is not described.

4. Adjudication Method for the Test Set:

This information is not provided in the document.

5. If a Multi Reader Multi Case (MRMC) Comparative Effectiveness Study Was Done, and the Effect Size of How Much Human Readers Improve with AI vs Without AI Assistance:

This type of study is not applicable to this device. The Lobob Universal Contact Lens Cleaner is a consumer product (contact lens solution), not an AI-powered diagnostic or interpretive device that would involve human readers.

6. If a Standalone (i.e., algorithm only without human-in-the-loop performance) Was Done:

This is not applicable. The device is a physical product (contact lens cleaner), not an algorithm.

7. The Type of Ground Truth Used:

The "ground truth" in this context would likely be clinical outcomes related to contact lens use, such as:

Lens cleanliness (visual inspection or lab analysis)
User comfort
Presence/absence of adverse events (e.g., corneal staining, infection)
Visual acuity (though less likely to be directly impacted by a cleaner unless significant deposits were present)

The document does not specify how these outcomes were measured or adjudicated.

8. The Sample Size for the Training Set:

This information is not applicable as the device is not an AI algorithm requiring a training set. The clinical study described involved 72 eyes, which would be for evaluation/testing of the device's performance, not for "training" an algorithm.

9. How the Ground Truth for the Training Set Was Established:

This is not applicable as there is no training set for an AI algorithm.

Trade Name:	Lobob Universal Contact Lens Cleaner
Predicate Device:	Lobob Cleaner (P950031)

Safety and Effectiveness Information:

Lobob performed non-clinical and clinical testing on the device. The non-clinical testing supports the safety and effectiveness of the device from microbiology, toxicology, chemistry and manufacturing perspectives. Clinical data were obtained from a multi-center study involving a hydrophilic contact lens consisting of 72 eyes followed for 3 months. This data was submitted to and evaluated by FDA in connection with its approval of PMA No. P950031.

Dear Mr. Manelli:

We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal laws or regulations.
