Is It a Good Idea to Tape the Eyelid Down at Night As Upper Eyelid is Retracting?

The patent is then instructed to pull down the upper eyelid manually several times during the day and tape it down nightly.  Since this is not your situation, you might try lid massage during the day and taping the eyelid down at night.  Be careful not to put too much pressure on the eye and also be careful not to scratch the eye.

This is not only okay, but it is something I recommend to patients while we wait for scarring to evolve and soften.

I often recommend using Breath Right nasal strips  because of its good "sticking power".

Yes, taping the eyelid down at night can help stretch the skin following eyelid surgery if the skin is retracting.  Gentle massage during the day may also help.  Some eyelid creams may also help relax the skin and scar.  If the scar is thick, it could be treated with the pulsed dye laser or the Fraxel re:store 1550 laser to help it relax. 

It is very important to protect the cornea after blepharoplasty surgery.  Your physician will instruct you with the best methods and "taping" may be one of them.
