A deformable intracapsular implant device for shaping an enucleated lens capsule sac for use in cataract procedures and refractive lensectomy procedures. In one embodiment, the intraocular implant devices rely on thin film shape memory alloys and combine with the post-phaco capsular sac to provide a biomimetic complex that can mimic the energy-absorbing and energy-releasing characteristics of a young accommodative lens capsule. In another embodiment, the capsular shaping body is combined with an adaptive optic. The peripheral capsular shaping body carries at least one fluid-filled interior chamber that communicates with a space in a adaptive optic portion that has a deformable lens surface. The flexing of the peripheral shaping body in response to zonular tensioning and de-tensioning provides an inventive adaptive optics mechanism wherein fluid media flows between the respective chambers “adapts” the optic to increase and decrease the power thereof. In one embodiment, the capsular shaping body carries a posterior negative power adaptive optic that can be altered in power during accommodation to cooperate with an independent drop-in exchangeable intraocular lens.

Biocompatible intraocular microspheres and implants include an alpha-2 adrenergic receptor agonist and a polymer associated with the alpha-2 adrenergic receptor agonist to facilitate release of the alpha-2 adrenergic receptor agonist into an eye for an extended period of time. The alpha-2 adrenergic receptor agonist may be associated with a biodegradable polymer matrix, such as a matrix of a two biodegradable polymers. The implants may be placed in an eye to treat or to prevent the occurrence of one or more ocular conditions, to reduce one or more symptoms of an ocular condition, such as an ocular neurosensory disorder and the like, to enhance normal retinal function and/or to lower intraocular pressure.

The present invention provides a method of treating an ocular condition in an eye of a patient, comprising the step of placing a biodegradable intraocular implant in an eye of the patient, the implant comprising a prostamide and a biodegradable polymer matrix that releases drug at a rate effective to sustain release of an amount of the prostamide from the implant to provide an amount of the prostamide effective to prevent or reduce a symptom of an ocular condition of the eye, wherein said ocular condition is elevated IOP and said implant is placed in an intracameral location to dilate the outflow channels of the eye emanating from Schlemm's Canal.

An apparatus and a method are described herein related to the art of augmented reality type monitor virtualization. A monitor-virtualization system, such as a head-mountable device, an ophthalmic device or an intraocular implant, can render a virtual monitor in augmented reality. A liquid lens or an optical phased array can position the virtual monitor in space by optical means. A dimmable occlusion matrix can be additionally operated such as to make the image of the virtual monitor substantially opaque. A coordinator module can synchronize the activities of monitor positioning and occlusion masking. The virtual monitor can be anchored to real-world artifacts using bokode technology. Various dimming modes of the occlusion matrix reduce operator fatigue. The apparatus may operate in smart sunglass mode when the virtual monitor function is paused. The virtual monitor can be hidden or visualized differently when thresholds in terms of user geolocation or viewing angle are breached.
