The device is indicated for the storage of contact lenses and is designed to minimize microbial contamination on its surface, not to diagnose a condition.
No
The device is a physical contact lens case infused with silver, not a software application.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is for the "storage of soft (hydrophilic) contact lenses with AQuify® Multipurpose Solution." This is a physical storage function for a medical device (contact lenses), not a diagnostic test performed in vitro on biological samples.
- Device Description: The description focuses on the physical properties of the lens case (infused with silver) and its ability to reduce bacterial growth on the case surface. It does not describe a test or assay for detecting substances or conditions in a biological sample.
- Lack of IVD Characteristics: The document does not mention any of the typical characteristics of an IVD, such as:
- Analyzing biological samples (blood, urine, tissue, etc.)
- Detecting or measuring specific analytes (glucose, antibodies, DNA, etc.)
- Providing diagnostic information about a patient's health status.
- Predicate Device: The predicate device listed is a "Contact Lens Case," which is consistent with a non-IVD device.
In summary, the ProGuard™ Lens Case is a medical device accessory designed for the storage of contact lenses, not a diagnostic tool.

Device Description
Data indicate that lens cases are a significant source of microbial contamination. The ProGuard Lens Case is a contact lens storage case that is infused with silver to help minimize contamination on the lens case surface. Laboratory testing showed that the silver ions reduce bacterial growth of Pseudomonas aeruginosa and Citrobacter amalonaticus on the case surface after 24 hours. No significant reduction was observed in the ProGuard lens case with S.epidermidis, S. aureus, P. mirabilis and S. marcescens (2 isolates).

Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
Non-clinical Studies: A series of nonclinical studies were completed to demonstrate the substantial equivalence of the ProGuard Lens Case to the predicate device. All testing was conducted in accordance with and in conformance to applicable device regulations. Results demonstrate the lens case is non-toxic and biocompatible, and is comparable to other currently marketed contact lens cases. Results from all tests demonstrate the substantial equivalence of the case to other to previously FDA cleared devices.
Microbiology:
Direct Microbial Challenge Studies: In a series of direct microbial challenge studies, ProGuard lens cases and regular lens cases were exposed to saline suspensions of 8 bacteria isolates and incubated at room temperature. After 4 hours there was no difference between the ProGuard lens case and the regular lens cases. After 24 hours the ProGuard lens cases showed significant reduction of 3 of the 8 bacteria isolates tested (P. aeruginosa GSU3, P. aeruginosa ATCC 9027, C. amalonaticus). There was no significant reduction difference between the ProGuard lens case and the regular lens case for S.epidermidis, S. aureus, P. mirabilis and S. marcescens (2 isolates).
Determination of Silver in the Lens Case & Lenses: In this study, atomic absorption was used to determine the concentration of silver found in the soaking solution of a ProGuard Lens Case and lenses exposed to the lens case. Under the conditions of the study, the results demonstrated that the average amount of silver found in a lens case cycled with AQuify MPS was approximately 30ppb. Lenses cycled in the same solution demonstrated a silver concentration ranging from 0.001 to 0.010µg/lens.
Cytotoxicity: A series of cytotoxicity studies were conducted to demonstrate the safety and substantial equivalence of the ProGuard Lens Case. Results of the testing demonstrated that the lenses case is non-cytotoxic and is a non-irritant.
USP Elution Test of Extracts of Case and Lid - A Reactivity Grade of zero (0) was observed for components of the ProGuard Lens Case.
USP Direct Contact Test of Extracts of Case and Lid - A Reactivity Grade of zero (0) was observed for the components of the ProGuard Lens Case.

USP Elution Test of with Karats MPS - A Reactivity Grade of zero (0) was observed for AQuify Multipurpose Solution stored in the ProGuard Lens Case.
ISO Ocular Irritation Test of Lens Case Base - ProGuard Lens Case bases were evaluated according to ISO 10993-10 for ocular irritation in the rabbit using saline and cottonseed oil extracts. Ocular scores were neqative for all test and control eves at 1, 24, 48 and 72 hours.
ISO Ocular Irritation Test of Aqua Lens Case Caps - ProGuard Lens Case caps were evaluated according to ISO 10993-10 for ocular irritation in the rabbit using saline and cottonseed oil extracts. Ocular scores were negative for all test and control eves at 1. 24. 48 and 72 hours.
ISO Ocular Irritation Test of White Lens Case Caps - ProGuard Lens Case caps were evaluated according to ISO 10993-10 for ocular irritation in the rabbit using saline and cottonseed oil extracts. Ocular scores were negative for all test and control eves at 1, 24, 48 and 72 hours.

Systemic Toxicity of Test Extracts of Aqua Lens Case Caps - ProGuard Lens Case caps were evaluated according to USP and ISO 10993-11 for systemic toxicity in the mouse. using saline and cottonseed oil extracts. No evidence of systemic toxicity was observed.
Systemic Toxicity of Test Extracts of White Lens Case Caps - ProGuard Lens Case caps were evaluated according to USP and ISO 10993-11 for systemic toxicity in the mouse, using saline and cottonseed oil extracts. No evidence of systemic toxicity was observed.
Clinical Study: Two clinical studies were conducted to evaluate the performance of the ProGuard Lens Case versus a standard control lens case.
Clinical Study #1: This study was one month clinical trial with 39 subjects using AQuify MPS. Each subject in the trial used one bowl of a ProGuard Lens Case and one bowl of a control case to store their lenses. For the control lens cases, after disinfection, subjects were instructed follow the case care instructions for the control case (e.g., empty the solution, rinse with fresh AQuify MPS and leave open to air dry). For the test case, the subjects followed one of the following case care regimen:
Test Case Regimen 1 - the case was emptied rinse with AQuify MPS, then re-capped
Test Case Regimen 2 - the case was emptied, rinse and re-filled with fresh Aquify MPS.
At the conclusion of the study, the ProGuard Lens Cases had a statistically significantly lower degree of bacterial contamination than the control lens cases - 26% (test case) versus 67% (control case). This study also demonstrated that recapping the ProGuard Lens Case an increase the microbial contamination of the case.
Clinical Study #2: This study was a one month clinical trial with 40 subjects using AQuify MPS with their lenses stored in one bowl of the ProGuard Lens Case and one bowl of the control lens case. After disinfection, the subjects were instructed to empty the cases, rinse with AQuify MPS and then re-cap the cases. In this study, the ProGuard Lens Cases had a statistically significantly lower degree of bacterial contamination than the control lens cases - 38% (test case) versus 63% (control case).
Key Metrics (Sensitivity, Specificity, PPV, NPV, etc.)
Clinical Study #1: ProGuard Lens Cases had a statistically significantly lower degree of bacterial contamination than the control lens cases - 26% (test case) versus 67% (control case).
Clinical Study #2: ProGuard Lens Cases had a statistically significantly lower degree of bacterial contamination than the control lens cases - 38% (test case) versus 63% (control case).
