摘要:
A method for prophylactic therapy for post-cataract extraction posterior capsular opacification of an eye having a lens posterior capsule, the method including the step of irradiating the lens capsule with laser radiation so as to destroy cells which remain in the lens capsule after extraction of the cataract, the laser radiation being substantially absorbable in water and of a level less than that required to rupture the lens capsule.
摘要:
Disclosed are methods and devices useful for imaging blood-containing tissue, for example for angiography, especially retinal angiography, whereby an image is generated by dividing pixels of an image acquired at some wavelength range by corresponding pixels of an image acquired at a different wavelength range. In some embodiments, a first wavelength range includes predominantly light having wavelengths between about 400 nm and about 620 nm and a second wavelength range includes predominantly light having wavelengths between about 620 nm and about 800 nm.
摘要:
A sensory substitution device (SSD) for providing a person with neural signals responsive to features of an environment, the SSD comprising: at least one camera that acquires an image of the environment; and at least one corneal neural stimulator that stimulates nerve endings in the cornea of an eye of the person to generate neural signals responsive to the image that propagate to the person's brain.
摘要:
An apparatus for objectively detecting ocular disorders adapted to the expedient examination of uncooperative patients generally comprises structures for collimating light into two predetermined paths for coaxial illumination of a person's right and left eye; structures for conditioning the collimated light; apertures for illuminating and retroflecting the collimated light by a person's eyes; and structures for detecting the relative intensities of the retroflected collimated light. A method for expediently examining uncooperative patients adapted to objectively detecting an ocular disorder comprises coaxially illuminating each eye; effecting a relative position between the apertures of an apparatus and a patient'eyes so that brief illuminating contact with the collimated light is effected; retroflecting the collimating light illuminating each eye; and measuring the relative intensities of the retroflected collimated light so that ocular disorders can be objectively determined.
摘要:
The invention provides a device for delivering electromagnetic radiation to a limbal area of an eye that transforms one or more beams of electromagnetic radiation that are incident on a first side into one or more emitted beams of the electromagnetic radiation where the one or more beams are arrayed in a cylindrical array, an array of one or more beams each beam having a cross sectional shape of a circular arc or an array comprising a beam having an annular cross section. The invention also provides a system for delivering electromagnetic radiation to the limbal area of an eye that includes one or more devices of the invention and a source of electromagnetic radiation. The system may be used in the treatment of glaucoma.
摘要:
A container having a main storage space for holding a matter, having an inlet/outlet opening and fitted with a PEF system. The PEF system comprises two or more electrodes disposed within said container and contacting the matter; and electric pulse source connected to the two or more electrodes and adapted to pass pulsed electric energy through the matter. The PEF system being activated to deliver a treatment protocol to the matter.
摘要:
The invention relates to compositions which induce in humans regeneration of the corneal endothelium. The compositions of the invention are of value in regenerating the corneal endothelium in humans, which is frequently damaged in the course of eye surgery and injuries. Such regeneration is very important to ensure the full functionality of the eye. The compositions of the invention comprise as active ingredient an adequate quantity of fibroblast growth factor (FGF) in a suitable physiologically acceptable vehicle. A preferred embodiment of the invention relates to a composition containing a certain quantity of hyaluronic acid and any other viscoelastic agent.
