The invention presents a universal eyedrop adapter designed for efficient and hygienic eye drop administration. The adapter features a one-way valve at the top to prevent backflow, a reduced internal lumen to minimize drop wastage, and a controlled flow design for precise dispensing. The base incorporates spiral grooves for a secure fit and to prevent outflow. Constructed with an antimicrobial material, the adapter is bug-resistant, ensuring a clean application process. The ergonomic design includes a bent angle and a rounded tip to mitigate the risk of eye injury. The administration process involves attaching the adapter to most eyedrop containers, cleaning it and the receiving periorbital region with a sterile wipe, squeezing to dispense a drop at the rounded tip, and then touching the lateral canthus. The user blinks to utilize surface tension and a lateral-to-medial movement, bringing the drop onto the ocular surface.

There is provided an eyedrop administrative device having a main device body, an eyedrop vessel for receiving and maintaining an eyedrop, a trajectory mechanism for expelling the eyedrop from the eyedrop vessel in an arced trajectory, thereby administering the eyedrop. Also provided is an eyelid lowering mechanism which is integrated into the eyedrop administrative device. Also provided is a method of administering an eyedrop by creating an eye pocket in the eye and expelling the eyedrop from the device in an arced trajectory from the device into the lower eyelid, also known as the eye pocket.

A dispenser for dispensing liquids, in particular ophthalmic liquids, for dispensing the medicine as individual drops is mounted on the neck of a reservoir, e.g., a bottle, and it is made of a flange connected to a bushing and with a domed tip situated on the opposite side of the bushing, the flange being fitted onto the neck of the reservoir and the bushing entering the neck of the reservoir, while a dispensing domed tip comprising a dispensing opening protrudes outside the reservoir. Inside the bushing and the domed tip there is a conical element placed therein, blocking the flow of liquids, the opening in the domed tip having an inner flange. The conical element has a flange at the base of the cone. The flange situated in the dispensing domed tip is ended from the inside with a fin directed towards the conical element blocking the flow of liquids.

A nozzle for a fluid delivery device includes a nozzle wall having opposing interior and exterior nozzle surfaces, and at least one opening through which fluid is configured to be selectively delivered to a target site of a user during use of the fluid delivery device. The at least one opening is defined by an inner opening surface and extends through the nozzle wall from the interior nozzle surface to the exterior nozzle surface. The exterior nozzle surface is configured to be directed toward the eye of the user during use of the fluid delivery device. The exterior nozzle surface is configured to be at least hydrophobic. At least a portion of the inner opening surface is configured to be hydrophilic.

A medical ophthalmic system uses a patient-specific face mask to establish a predefined alignment between the ophthalmic system and an eye of a patient. The patient-specific face mask may optionally provide a light proof enclosure for the eye. The face mask may be coupled directly to an ophthalmic device, or its housing/enclosure, of the ophthalmic system. The face mask may be 3D printed based on a 3D model of the patient's face.

Systems and methods are provided for determining a likelihood that a drop released from a bottle will land in an eye of a user. Each of an eye of a user and a tip of a bottle and illuminated and imaged to provide at least one image. An orientation of the bottle is determined via an inertial measurement unit, and a likelihood that a drop released from the bottle will land in the eye of the user is determined from the determined orientation and the at least one image.

An ocular medical injector is provided for drug delivery. A method includes inserting a puncture member of the medical injector into the eye until the puncture member reaches the suprachoroidal space (SCS). The puncture member defines a lumen therethrough. With the puncture member disposed within the SCS, a flexible cannula is advanced distally through the lumen of the puncture member, beyond the distal end portion of the puncture member and along the SCS towards a posterior region of the eye. The flexible cannula has an atraumatic distal tip and defines a lumen therethrough. With the distal tip of the flexible cannula disposed within the SCS beyond a distal end portion of the puncture member, a therapeutic substance is administered to the SCS.

A device includes a frame, a rotatable housing and a permanent magnet. The frame is configured to be worn adjacent an eye region of a wearer. The rotatable housing is coupled to the frame. The permanent magnet is coupled to the rotatable housing and includes a first surface having a first static magnetic polarity and a second surface having a second static magnetic polarity opposite the first static magnetic polarity. The rotatable housing is arranged to rotate the permanent magnet between a first position orienting the first surface towards the eye region of the wearer and a second position orienting the second surface towards the eye region of the wearer. Related apparatus, systems, techniques and articles are also described.

An ophthalmic speculum includes arms, a locking mechanism, and an air-flow system. The arms include a first arm and a second arm. Each arm has a retractor shaped to conform to an eyelid of a pair of eyelids of an eye. The retractors are substantially symmetrical about a lateral axis. The locking mechanism is coupled to the arms. The locking mechanism moves the arms to allow the retractors to retract the pair of eyelids, and fixes the arms into place to maintain retraction of the pair of eyelids. The air-flow system is coupled to at least one arm, and moves air in a region disposed outwardly from a surface of the eye.

Disclosed are devices and methods for delivering a sheet of tissue into the eye in such a way that damage to the tissue is minimized, damage to the eye during insertion and manipulation of the tissue is minimized, and the tissue is released and delivered in a precise and controlled fashion.
