    Abstract: An ophthalmic device is provided for a patient that has a basic prescription for distant vision, the ophthalmic device including a primary optic and a supplemental optic. The primary optic is configured for placement in the eye and has a base optical power configured to substantially provide the basic prescription. The supplemental optic has an optical power that is less than the optical power of the primary optic and is configured to provide, in combination with the primary optic, a combined optical power that provides the basic prescription of the patient. In addition, at least one surface of the primary optic is configured to deform in response to an ocular force so as to modify the combined optical power by at least 1 Diopter. The ophthalmic device may further include a movement assembly operably coupled to the primary optic that is structured to cooperate with the eye to effect accommodating deformation of the primary optic in response to an ocular force produced by the eye. The movement assembly may also be configured to provide accommodating axial movement of the primary optic.

    Abstract: A method for determining reflectivity of a tear film lipid layer of a patient and recommending a course of treatment based on the same. The method includes the steps of: measuring a tear film aqueous plus lipid layer relative reflectance spectrum using a wavelength-dependent optical interferometer; converting the measured tear film aqueous plus lipid layer relative reflectance spectrum to a calculated absolute reflectance spectrum; comparing the calculated absolute reflectance spectrum to a theoretical absolute lipid reflectance spectrum to determine a tear film lipid layer thickness; and determining a reflectivity value for the tear film lipid layer thickness at a first wavelength of light corresponding to ultraviolet, violet, or blue light.
