The ProGuard™ Lens Case is indicated for storage of soft (hydrophilic) contact lenses with AQuify® Multipurpose Solution.
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).

Device Description
The Focus® DAILIES®, Focus® DAILIES® Toric and Focus® DAILIES® Progressives (nelfilcon A) ONE-DAY CONTACT LENS are daily wear soft contact lenses intended for single use daily disposable wear. The Dailies lens is a spherical soft contact, Dailies toric lenses have a double thin zone design, and the Dailies Progressives lens is a progressive aspheric simultaneous vision soft contact lens. A constant near power profile is incorporated into each Progressive lens across the full range of distance powers. The near and intermediate powers are concentrated primarily in the central portion of the optical zone while the surrounding portion is weighted toward distance. The continuous changes in power across the surface of the lens allow patients requiring a reading addition of up to +3.00 diopters to see clearly at far, intermediate and near distances.
The lens material is 69% water and 31% nelfilcon A polymer (polyviny) alcohol partially acetalized with N-formylmethyl acrylamide). The lenses are tinted from edge to edge for visibility purposes with the color additive copper phthalocyanine (CuP).
Lenses are supplied sterile in foil sealed blister packs containing isotonic phosphateacetate buffered saline solution. The package storage saline may contain up to 0.02% Poloxamer 108.
The physical properties of the lens are:
- Refractive Index: 1.38 (hydrated)
- Center Thickness: 0.09 to 0.17 mm (0.10 at -3.00D; 0.15 at +3.00D)
- Light Transmittance: 96% (approx)
- Oxygen Permeability (Dk): [35° C, Fatt corrected] 26 x 10-11 (cm²/sec) (ml O2/ml x mm Hg)
