OASIS Medical, manufacturer and distributor of high quality disposable surgical instruments and ocular lubricating and cleansing solutions, has obtained a CE Mark opening the doors to the international market for their Soft Shield Collagen Corneal Shields which allow for ocular healing to take place by providing a protective barrier over the surface of the eye.

As the shield gradually degrades, a thin layer of collagen is released which helps lubricate the eye.

SOFT SHIELD® Collagen Corneal Shields are clear, pliable, thin film of highly purified bovine collagen that has been lightly cross-linked to provide the desired degradation time on the eye. SOFT SHIELD® Collagen Corneal Shields are hydrated dome side down and must be inverted before being placed on the eye.

Once applied to the eye, the hydrated shield will slowly absorb ocular fluids which contain collagenases and proteases.

These enzymes cause the shield to slowly lose shape and eventually degrade. The shield is thicker in the center and thin out towards the edge. When hydrated, the water content of the shield is 65% to 85% depending on the degradation time.

There are four dissolution rates: QS, 12, 24, and 72 hour. The QS and 12-Hour shields are used primarily following cataract surgery and are intended to dissolve completely on the eye under a patch within 1 day.

The 24-Hour and 72-Hour shields are used primarily following ocular injections, corneal trauma, and non-traumatic corneal conditions. They are intended to be placed on a non-patched eye and will remain on the eye, similar to a contact lens, for approximately the number of hours indicated. They will partially degrade during their time on the eye.

SOFT SHIELD® Collagen Shields are supplied sterile by electron beam irradiation in a double peel tray. The inner tray is intended to be used to hydrate the shield.
