incorporated direct current??? - do you mean interrupted direct current?

If so why would you do this?

Ptosis is not always due to a neuromuscular problem but when it is, it is an inablity to open the eyelid due to weakness of the levator palpabrae muscle. The upper fibres of the orbicularis occulii muscle is the direct antagonist of the levator palpabrae muscle

this seems a potentially dangerous form of electrical current to deliver to such a delicate part of the anatomy. It seems to me IDC carries considerable risk of harm

There is no evidence for this treatment for ptosis at least not as far as I can know - feel free to correct me if you know of such a clinical trial.

So we don't have any evidence for a treatment that is potentially risky and we are targeting the wrong muscle. Makes no sense to me.
