The position with the highest degree of eye-closure (improvement of 21.6%, p less then 0.001) and speed (improvement of 30.4 mm/s, p less then 0.001) was the combination of a posterior medial attachment and an inferior-posterior lateral attachment, which resulted in a near physiological closure in human cadaver. CONCLUSION Closure improved with an inferior lateral position due to increased force acting in the direction of closure. Posterior positioning increases force acting radially, towards the centre of eyelid move
