Abstract: A neck trial (170) is disclosed. The neck trial has a body (182) and a neck (186). The body has an exterior surface. The neck extends away from the body along a neck axis (190). At least one first line (194) is provided on the exterior surface, which extends in a first direction parallel to an inferior-superior axis of a patient when in use. At least one second line (196) is provided on the exterior surface, which extends in a second direction parallel to a medial-lateral axis of the patient in use. The number of first lines, or the position of the first line or lines relative to the second line or lines, is indicative of an amount of offset in the medial-lateral direction caused by the neck trial. The number of second lines, or the position of the second line or lines relative to the first line or lines, is indicative of an amount of leg-length in the inferior-superior direction caused by the neck trial. A kit of parts, a trial assembly and a method of trialling a joint of a patient are also disclosed.

Abstract: An electronic intraocular device is implantable into the capsular bag of a wearer's eye. In some cases, the intraocular device may include a femtoprojector. The femtoprojector projects images onto the wearer's retina when the electronic intraocular device is implanted in the wearer's eye. Different haptic designs may be used to keep the femtoprojector in position. In some embodiments, an imager is contained in a contact lens worn by the wearer. Images captured by the contact lens imager may be relayed to the intraocular femtoprojector. In some cases, the intraocular device may include an electronic capsular tension ring with a femtoimager. The femtoimager may capture images of the wearer's retina, for example for purposes of monitoring eye health.

The IOMD implant includes an enclosure shaped for implantation into an eye, a micro-display to emit images towards a retina, an energy storage unit to power the micro-display, a charging antenna for wireless charging of the energy storage unit via a power signal incident upon the first charging antenna, and a data antenna to wirelessly receive the image data for driving the micro-display to emit the images. The charging antenna and the data antenna are implantable into the eye with the IOMD implant.

Abstract: Implantable pressure sensors and implantable electronics should be packaged in hermetically sealed modules with biocompatible surfaces before being implanted. Packaging designs should be compact and cause little to no interference with the mechanical (and optical) properties or functions of the implant. For a pressure sensor in an intraocular lens, this means that the sensor and packaging should allow the lens to be folded so that it can be implanted through a small incision in the eye. An inventive implantable pressure sensor is coated with a silicone elastomer and hermetically sealed by a multilayer coating of SiOx and Parylene C, which may also encapsulate other components, including a microcontroller or processor, rechargeable batteries, sensors, resistors, capacitors, wireless transceivers, and/or antennas mounted on a transparent substrate.

Abstract: A method of implanting the prosthesis is disclosed. The method includes forming an opening in a host tissue of an eye. The method also includes forming a perimeter of a corneal graft. The method also includes forming a first passageway through the host tissue and a second passageway through the corneal graft. The first passageway and the second passageway can have the same diameter relative to an optic axis of the eye. The method also includes aligning the first passageway and the second passageway whereby the first passageway and the second passageway are in communication with one another. The method also includes positioning a body in the first passageway and the second passageway.

Abstract: A bioactive filamentary structure includes a sheath coated with a mixture of synthetic bone graft particles and a polymer solution forming a scaffold structure. In forming such a structure, synthetic bone graft particles and a polymer solution are applied around a filamentary structure. A polymer is precipitated from the polymer solution such that the synthetic bone graft particles and the polymer coat the filamentary structure and the polymer is adhered to the synthetic bone graft particles to retain the graft particles.

Abstract: In implementations of systems for management of dry eye syndrome, a palpebral fissure width is determined as a distance between a medial canthus and a lateral canthus of closed eyelids. An ideal eyelash length is generated based on the distance. Prostheses having the ideal eyelash length are attached to candidate eyelashes of an upper eyelid of the closed eyelids. The prostheses introduce a turbulence to airflow around a tear film which prevents the tear film from evaporating. Dry eye syndrome is managed by preventing the tear film from evaporating.

The beams of the first series have a respective first end connected to the outer peripheral ring, wherein the total area of void portions within the meshes of the reticular structure is between 50 and 99.9% of the surface area of the reticular structure, wherein the beams of both the first and second series have both ends connected to the outer peripheral ring.

Abstract: Introduced here are novel techniques for augmenting the lips through superficial linear injection of dermal fillers. At a high level, these techniques are representative of a two-step approach to augmentation. In the first stage, an implement that is appropriately positioned inside a lip can be moved sideways—an action referred to as a “side push.” In the second stage, dermal filler can be ejected from the implement so as to fill the resulting void. These techniques can be used by healthcare professionals to reshape the lips for medical or aesthetic purposes. These techniques were developed in an attempt to permit augmentation of the outer surface of a lip so as to increase its volume by expanding sideways while turning the lip outward. With these techniques, the desired result—namely, a plumper lip—may be readily and consistently achievable.
