Ophthalmic drape with tear line and method
First Claim
1. A method of applying an ophthalmic drape to the upper and lower eyelids of an eye of a patient, the method comprising the following steps:
- (a) providing a surgical drape comprising a sheet having a periphery, an aperture spaced from the periphery of the sheet, and at least two tear lines in the sheet extending substantially from the aperture substantially to the periphery to divide the sheet into two sections; and
a field of skin compatible adhesive adjacent the aperture, the field being traversed by each of the tear lines so as to divide the field into at least two portions, one along each of the two sections of the sheet;
(b) tearing the sheet partially or completely along at least one of the tear lines; and
(c) adhering one of the portions of the field of skin compatible adhesive to one of the eyelids; and
(d) adhering the other portion of the field of skin compatible adhesive to the other eyelid.

Abstract
An ophthalmic surgical drape and a method of applying the drape to a patient. The ophthalmic surgical drape is made from a sheet having an aperture in the interior of the sheet, and at least two tear lines in the sheet extending from the aperture. The drape also has a field of skin compatible adhesive adjacent the aperture, with the field being traversed by the tear lines so as to divide the field into at least two portions. The drape may be provided in a folded condition in which tearing can be accomplished so as to divide the drape into two sections before the drape is unfolded. Also disclosed are two tear lines disposed along an oblique angle, and a method of applying the drape.

9. An ophthalmic surgical drape comprising:
-
a sheet having a periphery, an aperture spaced from the periphery of the sheet, and a tear line in the sheet extending in opposite directions from the aperture to the periphery of the sheet to divide the sheet into two portions; and
a field of skin compatible adhesive adjacent the aperture, the field being traversed by the line of perforations so as to divide the field into two adhesive portions, one on each of the two portions of the sheet;
the sheet being folded in the direction perpendicular to the tear line, and also along the tear line such that the sheet can be unfolded over the tear line and the two portions of the sheet separated from one another by grasping them and tearing the sheet along the tear line before the sheet is unfolded with respect to any fold that is perpendicular to the tear line. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16, 17)

18. An ophthalmic surgical drape comprising:
-
a sheet having a periphery, an aperture spaced from the periphery of the sheet, the aperture having opposite sides, and two tear lines extending at oblique angles relative to one another substantially from opposite side of the aperture substantially to the periphery of the sheet to divide the sheet into two portions; and
a field of skin compatible adhesive adjacent the aperture, the field being traversed by the tear lines so as to divide the field into two adhesive portions, one on each of the two portions of the sheet. - View Dependent Claims (19, 20, 21, 22, 23)

24. A method of folding an ophthalmic drape to the upper and lower eyelids of an eye of a patient, the method comprising the following steps:
-
(a) providing a surgical drape comprising a sheet having a opposite end edges and opposite side edges, an aperture spaced from the edges of the sheet, and at least two tear lines in the sheet extending substantially from the aperture substantially to the opposite side edges to divide the sheet into two sections, the aperture being offset toward one of the opposite end edges but being centered with respect to the opposite side edges; and
a field of skin compatible adhesive adjacent the aperture;
(b) folding the drape along a first fold line that is generally parallel to the opposite end edges to cover the tear line;
(c) folding the first folded area of the drape along at least one second fold line that is generally parallel to the first fold line to uncover the tear line;
(d) folding the drape in third along third and fourth fold lines that are generally perpendicular to the first and second fold lines;
(e) folding the drape along a fifth fold line bisecting the aperture in the direction generally parallel with the third and fourth fold lines; and
(f) maintaining the field of skin compatible adhesive in an outward direction throughout the steps (b)-(e) so that the drape does not cover the field of skin compatible adhesive. - View Dependent Claims (25, 26, 27)

28. A method of folding an ophthalmic drape to the upper and lower eyelids of an eye of a patient, the method comprising the following steps:
-
(a) providing a surgical drape comprising;
a sheet having a opposite end edges and opposite side edges, an aperture spaced from the edges of the sheet, and at least two tear lines in the sheet extending substantially from the aperture substantially to one of the opposite end edges, constituting the first end edge, to divide the sheet into two sections, the aperture being offset toward the first end edge but being centered with respect to the opposite side edges; and
a field of skin compatible adhesive adjacent the aperture;
(b) folding the drape along a first fold line that is generally parallel to the opposite end edges to cover the aperture and at least a portion of the tear lines;
(c) folding the first folded area of the drape along at least one second fold line that is generally parallel to the first fold line to substantially completely uncover the tear line;
(d) folding the drape in third along third and fourth fold lines that are generally perpendicular to the first and second fold lines;
(e) folding the drape along a fifth fold line bisecting the aperture in the direction generally parallel with the third and fourth fold lines; and
(f) maintaining the field of skin compatible adhesive in an outward direction throughout the steps (b)-(e) so that the drape does not cover the field of skin compatible adhesive. - View Dependent Claims (29)
