Hydrophilic surfactant compositions are disclosed that include a surfactant component and a stabilizer component. The surfactant can be coated on a surface by depositing a surfactant solution on at least a portion of the surface, then drying the surfactant solution to form the dry coating. The surfactant compositions, when applied to a substrate, can provide a hydrophilic surface that retains its hydrophilic character over time, at elevated temperatures, or both.

Surfactant composition having stable hydrophilic character

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.

An ophthalmic drape that can easily be adhered to both the upper and lower margins of the eye without requiring the use of separate instruments for cutting and adjusting. The drape includes a sheet of material with an aperture positioned away from the periphery of the sheet. The drape has two fields of skin compatible adhesive, one on one side of the sheet near the aperture, the other on the other side of the sheet near the periphery. Once the first field of skin compatible adhesive has been adhered to one of the patient's eyelids, the section of the drape supporting the second field of skin compatible adhesive can be folded upwards and doubled back on the drape. The second field of skin compatible adhesive, which had been side away from the patient before folding, is turned side towards the patient after folding. The second field of skin compatible adhesive is then conveniently positioned to be adhered to the remaining eyelid of the patient.
