Abstract: An apertured polymeric film web having a first surface, a second surface generally parallel to and spaced apart from said first surface, and a plurality of fluid passageways extending between the first surface and the second surface to place the first surface and the second surface in fluid communication with one another. The web is formed of a polymeric film comprising at least one bulk modified layer, the bulk modified layer comprising a substantially homogeneous, stabilized dispersion comprising a comparatively low surface energy material in a polymeric material.      The comparatively low surface energy material, referred to herein as a hydrophobic additive, imparts hydrophobicity to the web's first surface, thereby promoting enhanced effectiveness in transporting fluid away from the first surface of the web, particularly when used in combination with a hydrophilic adhesive applied to the web's second surface in a topsheet system of the present invention. In a preferred embodiment the web is used as a topsheet in an absorbent article. In a more preferred embodiment, the web is used as a topsheet in an absorbent article, and the topsheet further includes a hydrophilic adhesive deposited thereon. When used as a topsheet in an absorbent article, the topsheet is peripherally joined with a backsheet and an absorbent core is positioned between the second surface of the topsheet and the backsheet. The second surface of the topsheet is preferably joined to the absorbent core by the hydrophilic adhesive.

Abstract: A method for optimizing a prescription for laser-ablation corneal treatment or ophthalmic implant includes the steps of receiving a measured correction prescription for a current patient having a classification element associated therewith, the prescription having been measured using wavefront determination. A database of treatment outcomes on a plurality of previously treated patients is accessed, each treated patient outcome having associated therewith at least one classification element and comprising a preoperative wavefront-determined correction prescription and a postoperative visual profile. From the treatment outcomes in the database is calculated an average difference between the preoperative prescription and the postoperative profile for at least some of the previously treated patients having a classification element in common with the current patient. Finally the current patient correction prescription is adjusted commensurate with the calculated average difference to form an optimized prescription.
