Self-Adhering Magnetic Device to Treat Corneal Exposure

Who can join

Ages 18 to 80 · All sexes

Inclusion Criteria:

* Males and females ages 18-80 years old.
* Patients with recent corneal abrasion and no signs of infection in the examination
* Patients with lagophthalmos
* Normal Controls

Exclusion Criteria:

* Individuals with adhesive or tape allergies.
* Individuals with a history of metal pieces/shavings embedded in the eye (such as from welding or metalworking)
* Individuals with eye infections

About the study

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.
