Physical principles

An adjustable ptosis crutch is a device that raises the drooping eyelid of the patients suffering from ocular myasthenia gravis or drooping of the eyelid as a result of weak muscles of the eye. The basic design of ptosis crutches consist of a flexible plastic material with two angled clips to fit on the frames of the patient's glass. The two clips are connected by an arched support so that it can be adjusted to allow free opening and closing of the eye for proper eye lubrication. These crutches can be easily removed and then fitted again by the patient.
