摘要： Embodiments of the technology relate to a contact lens having a core that is covalently coated by a hydrogel layer, and to methods of making such a lens. In one aspect, embodiments provide for a coated contact lens comprising a lens core comprising an outer surface; and a hydrogel layer covalently attached to at least a portion of the outer surface, the hydrogel layer adapted to contact an ophthalmic surface, wherein the hydrogel layer comprises a hydrophilic polymer population having a first PEG species and a second PEG species, the first PEG species being at least partially cross-linked to the second PEG species.

摘要： A stimulation system stimulates anatomical targets in a patient for treatment of dry eye. The system may include a controller and a microstimulator. The controller may be implemented externally to or internally within the microstimulator. The components of the controller and microstimulator may be implemented in a single unit or in separate devices. When implemented separately, the controller and microstimulator may communicate wirelessly or via a wired connection. The microstimulator may generate pulses from a controller signal and apply the signal via one or more electrodes to an anatomical target. The microstimulator may not have any intelligence or logic to shape or modify a signal. The microstimulator may be a passive device configured to generate a pulse based on a signal received from the controller. The microstimulator may shape or modify a signal. Waveforms having different frequency, amplitude and period characteristics may stimulate different anatomical targets in a patient.
