摘要:
The present invention relates to improving, at least in part, a deficiency in dark adaptation for an individual. The therapy for dark adaptation includes local administration of a retinoid, such as a Vitamin A or a derivative thereof, such that deleterious side effects seen with systemic administration are avoided.
摘要:
The present invention addresses the treatment of age-related macular degeneration using regulation of pathogenic mechanisms similar to atherosclerosis. In further specific embodiments, compositions that increase reverse cholesterol transport are utilized as therapeutic targets for age-related macular degeneration. In a specific embodiment, the lipid content of the retinal pigment epithelium, and/or Bruch's membrane is reduced by delivering Apolipoprotein A1, particularly a mimetic peptide.
摘要:
Described are compositions, methods, and articles of manufacture for the closure of retinal breaks with a non-toxic polymer. Transformation to a gel-like coat is achieved by photochemical reactivity, chemical reactivity, and by physicochemical response.
摘要:
An improved viscosurgical method involving the administration of a viscoelastic and a corresponding degradative agent, such that the post-operative intraocular pressure spike often observed following the use of viscoelastics in ophthalmic surgery is minimized, and an apparatus and clinical kit useful in the method are provided.
摘要:
The present invention relates to altering the physical and/or chemical properties of at least part of at least one tissue in the eye. In a specific embodiment, it relates to the treatment and/or prevention of myopia. An activating energy source is utilized to photopolymerize or crosslink molecules in the sclera, thereby increasing the strength of the tissue. The individual is administered a crosslinking reagent or photopolymerizable molecule that becomes associated with the membrane, which is then precisely exposed to an energy source, such as light or ultrasound.

摘要:
The present invention relates to lenses that are capable of post-fabrication power modifications. In general, the inventive lenses comprise (i) a first polymer matrix and (ii) a refraction modulating composition that is capable of stimulus-induced polymerization dispersed therein. When at least a portion of the lens is exposed to an appropriate stimulus, the refraction modulating composition forms a second polymer matrix. The amount and location of the second polymer matrix may modify a lens characteristic such as lens power by changing its refractive index and/or by altering its shape. The inventive lenses have a number of applications in the electronics and medical fields as data storage means and as medical lenses, particularly intraocular lenses, respectively.
摘要:
This invention relates to a steerable articulation coupler for effecting rapid connection of the two sections of a ground vehicle. The coupler also provides for rapid automatic connection of the power transmission shaft. The coupler consists of a socket member and an insertion member. The insertion member includes a forward semi-spherical support surface, a rearward large diameter support surface, a guide receptacle and a set of alignment members. Counterparts on the socket member cooperate with the insertion member to align the two members.
摘要:
The disclosure concerns altering the mechanical and/or chemical property of a body tissue, particularly an ocular tissue. In specific cases, it concerns altering or stabilizing the shape of the cornea, such as in a subject suffering or at risk for ectasia or keratoconus. In other specific cases, it concerns strengthening the sclera in a subject suffering or at risk for myopia. The invention employs light irradiation of a photoactivatable compound, such as one that applies crosslinking to the tissue, for example.
