The palpebral fissure height (PFH) was measured, and the corrective gain of the paralytic upper eyelid was calculated. Efficacy was evaluated through symmetrical blinks, the corrective gain, and the electrical activity of the frontalis muscle. Safety was evaluated through subjective sensations and complications.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 16 volunteers were recruited. After device\u2010assisted correction, the patients reported subjective improvement of peripheral vision, and the mean PFH increased from 3.4\u2009\u00b1\u20091.6 to 7.2\u2009\u00b1\u20091.4\u2009mm, with a mean gain of 3.7\u2009\u00b1\u20090.9\u2009mm (range: 2.0\u20105.0\u2009mm). The device could lift the paralytic eyelid without causing severe discomfort or complications. It also showed effects on the electrical activity of the frontalis muscle. Over the periorbital skin, posttest erythema was observed in one patient, mild hot sensation in two, and mild warm sensation in five. Subjective and objective evaluation of six patients who underwent two trials revealed no significant difference between the first and second trials (\n
