![]() In our prior work we established proof-of-concept data demonstrating safety and efficacy for temporary management ptosis up to 2 hour per day for 2 weeks. The hydrophyllic properties (FDA, 1997) may be beneficial to the eyelids, which are often moist. This material is extremely thin, transparent, and oxygen permeable with an established safety profile for days to weeks of wear. Tegadermâ„¢ (Chen, 1997), already used for IV catheter securement, wound dressing, and as a protective eye covering (FDA, 1997). ![]() Problems with extended external non-surgical adhesion to the skin of the eyelid may be solved with hydrocolloid-based medical adhesives e.g. The increased magnetic force at a fraction of the size has led to attempts for other medical applications including implantation for gastroesophageal reflux disease (Ganz, 2013), in dental prosthetics (Uribe, 2006), ocular reconstructive surgery (de Negreiros, 2012), and glaucoma (Paschalis et. They generate the strongest static magnetic fields yet possible, (1.3T compared to 0.4T of conventional ferrite magnets) (Cyrot, 2005) with exceptional uniaxial magnetocrystalline anisotropy, which makes them resistive to demagnetization (Chikazumui, 1997). A newer class of permanent magnets made of alloys of neodymium (Nd), iron (Fe) and boron (B) might provide the technology needed to develop a feasible external magnetic device. It is possible that earlier magnetic materials lacked the strength (at sizes which were acceptable to patients) to effectively restore the blink, or methods of implantation or external mounting were not effective. Despite this seemingly straight-forward application, permanent magnets for eyelid movement disorders have not thus far become an available treatment. An external device, if able to generate an appropriately balanced force, could restore eyelid movement by performing the paralyzed function for example, a ptotic (droopy) eyelid could be opened, and the functioning eyelid closure muscle could overcome the device's force (Conway, 1973 Barmettler et. Why Should I Register and Submit Results?Ä«lepharoptosis (incomplete opening of the eyelids) occurs because of a disruption in the normal agonist-antagonist neuro-muscular complex balance.
