    摘要: There is described a contact lens package containing a bowl for holding a contact lens and a flange around the bowl which may be made from a different polymer material than the bowl. The packages comprise at least one interface tab with at least one slot so that the second polymer material forming the flange can encapsulate the tab providing a mechanical interlock displaying good flexural strength.

    摘要: A method of measuring the thickness of an ophthalmic lens includes forming an ophthalmic lens over a convexly curved surface of a forming optic, the ophthalmic lens including a light absorptive component, and with the ophthalmic lens remaining over the convexly curved surface of the forming optic, measuring the thickness of the ophthalmic lens using information about the light absorptive component of the ophthalmic lens and an intensity reference value associated with the forming optic. The method includes passing light having a wavelength through the ophthalmic lens and the forming optic, whereupon the light absorptive component of the ophthalmic lens absorbs some of the light passing through the ophthalmic lens. The light passing through the ophthalmic lens and the forming optic, which is not absorbed by the light absorptive component of the ophthalmic lens, is used to generate an image having pixel intensity data.

    摘要: The present invention relates to ophthalmic compositions and methods for the treatment of dry eye and other inflammatory ocular conditions. In particular, the present invention relates to a composition comprising an esterified anti-inflammatory lipid mediator, which is an ester of an anti-inflammatory lipid mediator that is a reaction product of the anti-inflammatory lipid mediator and a polyol wherein the majority of the anti-inflammatory lipid mediator is present in an ester form. In this way, the compositions are substantially free of an acid form of the anti-inflammatory lipid mediators. Anti-inflammatory lipid mediators can be selected from the group consisting of polyunsaturated fatty acids (e.g., omega-three and omega-six fatty acids), resolvins or a metabolically stable analog, protectins or a metabolically stable analog, lipoxins or a metabolically stable analog, prostaglandins or a metabolically stable analog, retinoic acids, endocannabinoids, metabolites thereof, and mixtures thereof. This composition can be topically delivered to the ocular surface via a preparation, solution, gel, ointment, and/or strip and/or a contact lens.
