Presbyopia is treated by a method which uses ablative lasers to ablate the sclera tissue and increase the accommodation of the ciliary body. Tissue bleeding is prevented by an ablative laser having a wavelength of between 0.15 and 3.2 micron. A scanning system is proposed to perform various patterns on the sclera area of the cornea to treat presbyopia and to prevent other eye disorder such as glaucoma. Laser parameters are determined for accurate sclera expansion.

The present invention relates to an accommodating intraocular lens, which is suitable for replacement of the natural crystalline lens of the eye within the capsular bag. The intraocular lens can include a retainer plate with an annular region surrounding a central opening, and an optical lens. The retainer plate acts as a foundation for the optical lens, as the retainer plate can be positioned near or at the posterior portion of the lens capsule. The optical lens can sit on the retainer plate, but is otherwise not attached to the retainer plate. The optical lens can overlap or fit within the central opening of the retainer plate. The retainer plate can include a lip portion integrally disposed on a region of the retainer plate, wherein the lip provides a surface for holding at least a portion of an intraocular lens.

An intraocular lens (IOL) includes an optic for focusing light and an accommodation assembly for axially moving and/or deforming the optic in response to naturally occurring actions of the eye, thus allowing a patient to more effectively focus on near objects. In addition, the optic may be multifocal or aspheric, wherein the maximum add power of the lens is combined with the increase in diopter power obtained through axial movement and/or deformation of the optic, resulting in enhanced accommodation.

An accommodating artificial ocular lens (AAOL) device including a lens optic portion connected to a pleated lens haptic portion to provide accommodation of vision of the eye.

Surgical method and apparatus for presbyopia correction and glaucoma by laser removal a portion of the sclera and/or ciliary tissue are disclosed. The disclosed preferred embodiments of the system consists of a beam spot controller, an articulated arm and an attached end-piece. The basic laser beam includes UV laser having wavelength ranges of (0.19-0.36) microns, generated from UV excimer lasers of ArF, XeCl or solid state lasers of Nd:YLF, Nd:YAG, Ti:sapphire with harmonic generation using nonlinear crystals. Presbyopia is treated by ablation of the treated surface tissue in predetermined patterns outside the limbus to increase the accommodation of the eye. Glaucoma is treated by decreasing of intra ocular pressure of the laser surgery.

The present invention provides embodiments of medical devices that provide for fluid drainage while maintaining patient comfort. An embodiment of the present invention provides a stent comprising a body portion and a kidney curl portion, the body portion comprising a tubular member having an axial lumen therein adapted to provide fluid communication from one body location to another. The kidney curl portion comprises an elongated filament that has a three-dimensional configuration that substantially conforms to the three-dimensional randomly convoluting calyx space of a kidney. In another embodiment, the kidney curl portion comprises a plurality of petals adapted to flare outwardly from the body portion distal end when in a free state in the space of a kidney so as to prevent the migration of the kidney curl portion into the ureter.

The invention is directed to an assembly comprising a haptic for fixation to, and manufacture in conjunction with, an intraocular lens to be implanted in the natural lens capsule of an eye. The haptic of the invention comprises a continuous ribbon forming an essentially oblong shape having anterior and posterior portions relative to the elliptical center of the haptic, wherein the ribbon loop includes two or more essentially congruent ribbon arches in each portion, and each ribbon arch has a natural index of curvature with an inner and outer edges. designed to expand the eye capsule and put tension on the zonules of the eye. The ribbon affixes to the lens on each side of the optic edge at a point or a series of points that provides suitable centration and stability of the optic, and to suspend the optic in the open capsular space. The material of the haptic is preferably somewhat flexible, and elastic, so as to provide a constant, positive force on the capsule throughout all phases of accommodation, thereby preserving tension of the zonules and allowing the capsule to change shape naturally. The haptic ribbons may be solid or of an open work structure to increase the amount of hydration available to the lens capsule. A secondary haptic ribbon, affixed to a plano optical plate, may be located on the posterior capsular surface and oriented so that the haptic arms extend through the capsular prime meridian to the anterior capsular surface at a 90° angle from the anterior haptic ribbons, thus providing for a capsular configuration as natural as possible, yet associated with an intraocular lens that may be inserted through an incision of less than 3 millimeters.
