A contact lens tool kit for placement of a contact lens on an eye is provided. The tool kit may include a contact lens tool. The contact lens tool may include an outer edge for selectively engaging a contact lens. The tool kit may also include a lens housing for containing a contact lens, the lens housing selectively engageable with the tool. Engagement of the tool and the lens housing permits reception of the contact lens by the contact lens tool and disengagement of the two permits removal of the contact lens by the tool. The lens housing may include a removable seal for draining solution through an aperture of the contact lens tool or lens housing.

Devices, systems, and associated methods for detecting drops dispensed by a dropper are provided. For example, a drop detection device may include a light source and a light detector configured to be coupled to a drop dispenser such that the light source and light detector are disposed proximal of a distal dispensing tip of the drop dispenser. The light detector may be configured to receive a reflected portion of a beam of light from the light source, which is reflected by a drop dispensed through the dispensing tip of the drop dispenser. In some embodiments, a processing circuit is configured to analyze a signal provided by the light detector to detect the dispensed drop.

Methods of treating an eye for an ocular condition such as placing a composite depot comprising a xerogel with embedded degradable particles into an anterior chamber of an eye to deliver a therapeutic agent. The xerogel is a hydrogel after exposure to intraocular fluid and is degradable. The degradable particles comprise the therapeutic agent and hydrolytically degrade in the anterior chamber to provide a controlled release of the therapeutic agent into the eye. Materials and processes for making depots are provided as well as alternative methods of their use.

Delivery devices, systems and methods are provided for inserting an implant into an eye. The delivery or inserter devices or systems can be used to dispose or implant an ocular stent or implant, such as a shunt, in communication with a suprachoroidal space of the eye. The implant can drain fluid from an anterior chamber of the eye to a physiologic outflow path of the eye, such as, the suprachoroidal space or other portion of the uveoscleral outflow path. The delivery or inserter devices or systems can be used in conjunction with other ocular surgery, for example, but not limited to, cataract surgery through a preformed corneal incision, or independently with the inserter configured to make a corneal incision. The implant can be preloaded with or within the inserter to advantageously provide a sterile, easy-to-use package for use by an operator.

A microfluidic flow restrictor that uses micron-sized beads to impede flow is described. The flow rate can be adjusted by adding or removing the beads using injection needles through self-sealing ports, one injection needle injecting or aspirating beads and another injection needle pushing or pulling fluid from outside of a bead trap within the flow restrictor. In alternative embodiments, the beads or other filler material can be trapped in a manifold bead trap such that they block a subset of fluid channels of the flow restrictor, allowing fluid to flow freely through the rest of the fluid channels. The flow restrictor can be integrated with a contact lens or implantable medical device for use in dispensing liquid therapeutic agents at flow rates of microliters per minute or moving body fluids at a controlled rate from one part of the body to another.

Provided are an injectable intraocular microgel and an injectable intraocular hydrogel that are safe to a human body and that can release a drug in the eye for a long period of time. This injectable intraocular microgel may have a form in which a drug is loaded on a hyaluronic acid microgel generated by causing hyaluronic acid copolymers to cross-link with each other through a w/o emulsion method.

The present invention relates to a kit for ophthalmic solutions contained in screw-cap dropper bottles, which comprises a fastening element and an applicator device for solutions, where the fastening element includes a manual gripping section followed by a cup-shaped cavity suitable for housing the screw-cap of the dropper bottle under pressure; such fastening element has the ability to serve as an extension in order to cap or uncap the screw-cap of the dropper bottle with ease, in addition to keeping such cap coupled to the fastening element while the bottle is in use.

The present invention relates to a contact lens for diagnosis and treatment of dry eye syndrome. The contact lens, according to the present invention, may diagnose dry eye syndrome by means of a change in an electric current occurring as a result of a field effect when a dry eye syndrome biomarker binds to a probe, and when dry eye syndrome is diagnosed, generates an electric current so that a gold film blocking a drug reservoir melts by the electric current, thereby enabling the release of a drug to be controlled.
