Embodiments of the present invention relate to methods and pharmacological or biological compositions to treat presbyopia in the human eye. According to the embodiments, pharmacological or biological compositions may be applied to or injected into an eye to effect a change in the accommodative ability of the eye by the breaking and reduction of lenticular bonds in the eye that may be responsible for presbyopia. The compositions may be applied in an inactive state and subsequently be activated to achieve a therapeutic effect. The application of energy may be used to either break the oxidized lenticular bonds and / or to activate one or more of the pharmacological or biological agents. The energy may be used in a focus treatment pattern to affect a change in the refractive characteristics of the eye and thereby reduce inherent optical distortions.

This invention effects a change in the accommodation of the human lens affected by presbyopia through the use of various reducing agents that change accommodative abilities of the human lens, and / or by applying energy to affect a change in the accommodative abilities of the human lens. This invention both prevents the onset of presbyopia as well as treats it. By breaking and / or preventing the formation of bonds that adhere lens fibers together causing hardening of the lens, the present invention increases the elasticity and distensibility of the lens and / or lens capsule.

Novel mercaptan compounds, particularly those including a photolabile protecting group, are described as well as methods of using the compounds for the prevention and treatment of ocular damage and disease.

Presbyopia may be treated by implanting a scleral prosthesis within a plurality of elongated pockets formed in the tissue of the sclera of the eye. The implanted prosthesis exerts traction on the sclera in the region overlying the ciliary body which expands the sclera and the underlying ciliary body. This restores the effective working distance of the ciliary muscle and increases the amplitude of accommodation. A prosthesis of the present invention that contacts the sclera of an eyeball comprises a body having a first end and a second end. The body has (i) a planform for expanding the contacted sclera to increase the effective working distance of the ciliary muscle of the eyeball, and (ii) a structure that stabilizes the prosthesis within the surgically formed pocket within the sclera of the eyeball.

Dithiol compounds and derivatives thereof are disclosed. The agents are useful for treating ocular disease, especially presbyopia and cataract. Also disclosed are novel mercaptan compounds, particularly those including a photolabile protecting group, as well as methods of using the compounds for the prevention and treatment of ocular damage and disease.

The invention discloses an electromagnetic wave spectrum therapeutic instrument. The electromagnetic wave spectrum therapeutic instrument comprises a lamp holder, an arc-shaped connecting piece, a transverse dead lever, a first lifting bar, a second lifting bar and a base, wherein the arc surface of the arc-shaped connecting piece is fixedly connected with one end of the transverse dead lever, and the two ends of the arc-shaped connecting piece are movably connected with the lamp holder through a rotating shaft; and the other end of the transverse dead lever is vertically connected with one end portion of the first lifting bar, the second lifting bar is inserted therein from the other end of the first lifting bar, the rod wall of the first lifting bar is axially provided with a plurality of through holes, the rod wall of the second lifting bar is provided with a clamping hole, the inner surface of the second lifting bar is provided with an elastic clamping piece, and the elastic clamping piece can pass through the clamping hole and the through hole. The electromagnetic wave spectrum therapeutic instrument can realize transverse and longitudinal movement of the lamp holder through the first lifting bar and the second lifting bar, improves the adjustment amplitude of the lamp holder, and is reasonable and compact in structure and convenient to use.

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.
