    Abstract: A lighting device providing emitted light with an adjustable correlated color temperature (CCT) is described. The lighting device comprises one or more light emitters and a controller configured to independently control each of the one or more light emitters. Each respective light emitter is configured to provide one or more spectral components of the emitted light, wherein the emitted light comprises a respective photoreceptor-to-photopic luminance activation ratio for each ocular photoreceptor class corresponding to an intended CCT of the emitted light. The respective photoreceptor-to-photopic luminance activation ratios comprise each of (a) a melanopsin (i)-to-photopic-luminance activation ratio; (b) a rhodopsin (R)-to-photopic-luminance activation ratio; (c) a long-wavelength sensitive opsin (L)-to-photopic-luminance activation ratio; (d) a middle-wavelength sensitive opsin (M)-to-photopic-luminance activation ratio; and (e) a short-wavelength sensitive opsin (S)-to-photopic-luminance activation ratio. Each of (a); (b); (c); (d); and (e) are within a defined range of a respective activation ratio of a blackbody radiator with the intended CCT. The emitted light may have variable excitation ratios for the five photoreceptors prompting a biological response matching that of a different blackbody radiator with changes that are invisible to the eye or difficult to perceive.

    Abstract: An ophthalmic imaging apparatus comprising: an illumination light source and an optical assembly for directing light from the light source into an eye of a subject; a photosensor array comprising a plurality of photosensors positioned for acquiring images of portions of a fundus of the eye; an objective lens positioned along an imaging axis intersecting a point on the fundus of the eye wherein the objective lens is positioned for refracting light that has been reflected by the fundus to form an image of the fund us on an image plane of the objective lens such that the image plane is positioned away from the photosensor array; and a microlens array comprising a plurality of microlenses wherein the microlens array is spaced away from and positioned behind the image plane and wherein the microlens array is positioned in between the image plane and the photosensor array such that each microlens in the array projects a different view of the image formed at the image plane thereby forming an array of elemental images on the photosensor array.

    Abstract: A cannula including a hollow cannula body having first and second tubular end portions, a collapsible section interconnecting the end portions, the collapsible section including a plurality of circumferentially spaced arms extending between the end portions, wherein in an extended configuration the arms are substantially aligned with the first and second end portions and in a collapsed configuration the arms deform to extend radially outwardly and a flange extending radially outwardly from the first end portion, so that the arms and flange are spaced apart when the cannula body is in the collapsed configuration, thereby allowing tissue to be sandwiched therebetween to thereby effect a seal between the cannula and the tissue so that the cannula provides an opening through the tissue.
