Self-Adhering Magnetic Device to Treat Corneal Exposure

Paralytic lagophthalmos can be difficult to treat and manage. It has a host of causes and effects, one of which (for the latter) is exposure keratopathy. Untreated, this can lead to corneal ulceration, inflammation, and potentially blindness. Despite a variety of attempts at treating this complex condition, none have satisfactorily reduced complications ranging from ease of use to aesthetics. With improvement in magnetic technology, however, that may change. Barmettler et al (2014) have demonstrated preliminary success of externally affixed magnets in closing both model and patient eyelids. As such, we hypothesize that magnetic devices can be used to treat corneal exposure by controlling eyelid position.
