Apparatus and methods for ocular treatment are provided. The apparatus can comprise an outer sheath and a microcannula movably housed within the outer sheath and having a proximal end, a distal end, a cavity, and a central longitudinal axis. The apparatus can include a first protrusion extending circumferentially inward at a distal end of the outer sheath and a second protrusion located on an outer circumferential surface of the microcannula. The apparatus can include multiple orifices disposed on the microcannula distal end, each of the orifices defining a channel extending transverse to the central longitudinal axis and configured to deliver a substance radially outwardly from the distal tip of the microcannula. The distal tip can extend out from a distal opening of the outer sheath when the microcannula is in an extended position and can be housed within the outer sheath when the microcannula is in a retracted position.

An implant that is to be implanted inside the eye of a person contains a laser projection scanning subsystem that is configured to “paint” an image of the scene that is before the person, on the retina. The image of the scene may be acquired by a digital camera that is attached to a head unit that may be worn by the person, and then transmitted to the implant. Other aspects are also described and claimed.

Compositions for treatment of cystinosis, products for administering eye drops, and products for storing contact lenses are provided. Compositions include solutions that can contain an effective amount of cysteamine to treat cystinosis, and an oil with a lower density than the solution. Also provided is a product including a bottle for containing a solution, the bottle being substantially free of O.sub.2. Also provided is a contact lens holder for storing one or more contact lenses in a solution, the holder including barrier layers reducing the amount of O.sub.2 entering the contact lens holder.

Medical devices and methods of treating subjects using such medical devices are described. The medical device may include a housing with at least two chambers including a first chamber adjacent to a second chamber; a barrier between the first chamber and the second chamber; and a soft, flexible base. The first and second chambers may be airtight, the barrier configured to establish fluid communication between the first chamber and the second chamber upon an application of force to the barrier.

Provided is an eye drop container having superior identifying power. The eye drop container includes an identifying indicium including a shape, a pattern, a color or combination thereof imparted to a lateral face of a container body, and a further identifying indicium identical or similar to the identifying indicium imparted to a lateral face of a cap part which is detachably attached to a dispensing mouth of the container body, the indicia making it possible to identify the unity of the container body and the cap part. The container is packaged by a sealing label that renders these identifying indicia visible when the cap part is attached to the container body.

This invention provides for a device and methods of dispensing a precise predetermined volume of liquid of discrete drops, vapor, or mist while preventing contamination due to Pull Back and ensuring precision dispensing.

An ophthalmic solution container has an accommodation part in which an ophthalmic solution is accommodated, and the accommodation part is composed of a laminate having a layer containing a cyclic olefin interpolymer (copolymer) and a layer containing a polyethylene resin provided outside the layer containing the cyclic olefin interpolymer (copolymer). The thickness of the layer containing the cyclic olefin interpolymer (copolymer) is 50 μm to 1,000 μm, and the thickness of the laminate is 300 μm to 2,000 μm. According to the container, it is possible to minimize sorption (adsorption and absorption) of the ophthalmic solution, it is possible to improve moisture barrier properties and minimize evaporation, and it is also possible to reduce the squeeze strength.

This invention provides a device for delivering medical implants, the device comprising a guide, a mandrel disposed internal to the guide, and a sleeve, wherein the sleeve is disposed external to the guide and is attached to the mandrel for movement therewith relative to the guide. Included among the various embodiments are devices configured for abutting a proximal surface against the palm of a user and presenting finger tabs for retraction of the guide relative to the mandrel. Optionally, a device of the present invention is a dual-mode device configured for being operated independently in each of an ejection mode and an injection mode. Optionally, a device of the present invention is configured for delivering an implant to the eye of a subject. Optionally, the eye implant is a retinal implant. Optionally, the implant comprises retinal cells.

A handheld cryoanesthesia or analgesia device for cooling a target area on cutaneous membranes, mucous membranes, and tissue of the mucocutaneous zone having an elongated body and a thermoelectric cooling system disposed within the elongated body. The thermoelectric cooling system is configured to physically contact and thermally couple the target area of the cutaneous membranes, mucous membranes, and tissue of the mucocutaneous zone to induce cryoanesthesia or analgesia. The thermoelectric cooling system includes a thermally-conductive cold tip, a thermally-conductive cooling power concentrator thermally coupled to the cold tip, at least one Peltier unit module thermally coupled to the cooling power concentrator, a heatsink thermally coupled to at least one Peltier unit module, a power source, at least one thermal sensor, and a controller operably outputting a control signal to the Peltier unit module to maintain a predetermined temperature.

A method for treating advanced primary angle closure glaucoma (PACG) includes steps of: S1, utilizing surgical peripheral iridectomy (SPI) to eliminate pupillary block; S2, utilizing goinosynchialysis (GSL) to separate peripheral anterior synechia (PAS) in the anterior chamber angle with the assistance of a gonioscope and a chopper; and S3, utilizing goniotomy (GT) to incise a dysfunctional trabecular meshwork and a Schlemm canal, so as to remove a dysfunctional trabecular meshwork, enhance outflow of aqueous humor, and reduce intraocular pressure.
