摘要： A system and method is disclosed for focusing an elastically deformable lens by making small changes in the equatorial diameter of the lens. A plurality of micro-electro mechanical system (MEMS) microengine assemblies are coupled to the periphery of the lens. The lens is focused by exerting and relaxing radial tension in a plane generally perpendicular to the optical axis of the lens. Each microengine assembly utilizes thermal beam actuator arrays in combination with mechanical links to move a slider unit that is coupled to an aperture in the periphery of the lens. The movement of the slider unit alters the diameter of the lens to change the focus of the lens. The lens diameter may be changed by amounts as small as one micron.

摘要： The present invention relates generally to a device and method for the treatment of retinal detachment, ocular hypertension and glaucoma, and increasing the amplitude of accommodation. In an illustrative embodiment, the device includes a tapered, mesh tube. Once the device is within the sclera, the mesh expands to deform the sclera. When the device is placed within the posterior sclera for the treatment of a retinal tear, the device expands deforming the sclera so that the retinal pigment epithelium comes in contact with the retinal tear to seal the tear. For the treatment of ocular hypertension, glaucoma and to increase the amplitude of accommodation, the device is placed within the anterior sclera over the posterior plicata of the ciliary body, which upon expansion causes the underlying ciliary body to deform, resulting in traction on the trabecular meshwork and deformation of the ciliary body, which causes lowering of intraocular pressure, and increases the amplitude of accommodation in patients with ocular hypertension or decreased accommodation.

摘要： The present invention relates generally to a device and method for the treatment of, ocular hypertension, glaucoma, and increasing the amplitude of accommodation. In an illustrative embodiment, the device includes a self-expanding wire. Once the device is within the posterior chamber between the iris and anterior lens capsule, the wire expands to compress the ciliary muscle. When the device is in place the scleral spur is moved posteriorly resulting in traction on the trabecular meshwork, which causes a reduction in intraocular pressure for the treatment of patients with ocular hypertension and glaucoma. In addition, the compression of the ciliary muscle increases the force of contraction of the ciliary muscle, which increases the amplitude of accommodation in patients with deficient accommodative amplitude and presbyopia.

摘要： A segmented scleral expansion band adapted for implantation within or fastening to a segment of the sclera of an eye lying outside of and adjacent to the ciliary body of the eye, is formed from a number of arcuate segments, curved to match the curvature of the globe of the eye, and joined together at each end to form a complete scleral expansion band. The band is implanted in the sclera of the eye by forming circumferential tunnels, inserting the band segments through the tunnels, and joining the ends of the segments to form a complete scleral expansion band. The scleral expansion band is useful in treating presbyopia and other ocular disorders.

摘要： A variable focus lens is constructed by making small changes in the equatorial diameter of an elastically deformable lens. The lens may be deformed by radial tension exerted in a plane generally perpendicular to the optical axis. The radial tension may be exerted by radially acting mechanical apparatus or by means of rings embedded or attached at the equator of the lens, whose diameter can be altered by heating, or by imposition of electrical or magnetic fields.

摘要： Presbyopia is treated by implanting within a plurality of elongated pockets formed in the tissue of the sclera of the eye transverse to a meridian of the eye, a prosthesis having an elongated base member having an inward surface adapted to be placed against the inward wall of the pocket and having a ridge on the inward surface of the base extending along at least a major portion of the major dimension of the base. The combined effect of the implanted prostheses is to exert a radially outward traction on the sclera in the region overlying the ciliary body which expands the sclera in the affected region together with the underlying ciliary body. The expansion of the ciliary body restores the effective working distance of the ciliary muscle in the presbyopic eye and thereby increases the amplitude of accommodation. Hyperopia, primary open angle glaucoma and/or ocular hypertension can be treated by increasing the effective working distance of the ciliary muscle according to the invention.

摘要： Presbyopia and hyperopia are treated by a method which increases the amplitude of accommodation by increasing the effective working distance of the ciliary muscle in the presbyopic eye. The effective working distance of the ciliary muscle can be increased by expanding the sclera in the region of the ciliary body. This expansion is accomplished by suturing to the sclera a relatively rigid band having a diameter slightly greater than that of the sclera in the region of the ciliary body, by weakening the sclera overlying the ciliary body, by surgical procedures or treatment with enzymes, heat or radiation, whereby intraocular pressure expands the weakened sclera, or by surgical alloplasty. The effective working distance of the ciliary muscle can also be increased by shortening the zonules by application of heat or radiation, by repositioning one or both insertions of the ciliary muscle or by shortening the ciliary muscle. Presbyopia is also arrested according to the invention by inhibiting the continued growth of the crystalline lens by application of heat, radiation or antimitotic drugs to the epithelium of the lens. Primary open angle glaucoma and/or ocular hypertension can be prevented/and or treated by increasing the effective working range of the ciliary muscle according to the invention.
