Abstract
A light-occlusive self adherent eye patch is disclosed comprising an absorbent pad having a nonadherent lower surface, a backing having a lower face adhered to the upper surface of the pad and extending outward from the periphery thereof, a light-occlusive pressure sensitive adhesive coating on the lower face of the backing to adhere the patch to the eye socket, and a removable liner protecting the lower surface of the pad and the adhesive prior to use. The pressure sensitive adhesive blocks at least 95 percent of the light of a preselected wavelength impinging on the adhesive.
Claims11
A self adherent eye patch comprising
- an absorbent pad shaped to fit over the eye having a nonadherent lower surface for contacting the eye and an opposing upper surface;
- a backing having a lower face adhered to said upper surface of said absorbent pad and extending outward from the periphery thereof;
- pressure sensitive adhesive coating on the lower surface of said backing for adhering the eye patch to the eye socket;
- said adhesive being capable of blocking at least 95 percent of the light of a preselected wavelength impinging thereon;
- a removable protective liner covering said nonadherent lower surface of said absorbent pad and the exposed portion of said pressure sensitive adhesive;
- and
- said eye patch having a moisture vapor permeability of at least 600 grams per square meter per 24 hours throughout and a conformability value of less than 800 grams.
A self adherent eye patch comprising:
- an absorbent pad shaped to fit over the eye having a nonadherent lower surface for contacting the eye and an opposing upper surface;
- a backing having a lower face adhered to said upper surface of said absorbent pad and extending outward from the periphery thereof;
- pressure sensitive adhesive coating on the lower surface of said backing for adhering the eye patch to the eye socket;
- said adhesive being capable of blocking at least 95 percent of the light of a preselected wavelength impinging thereon;
- and
- a removable protective liner covering said nonadherent lower surface of said absorbent pad and the exposed portion of said pressure sensitive adhesive.
A method of treating an eye defect or trauma comprising the step of covering the appropriate eye with a self adherent eye patch which contains a layer of a pigmented
- pressure sensitive adhesive rendering said eye patch capable of blocking at least 95 percent of the light of a preselected wavelength impinging thereon.
