Odds of Lower Lid Retraction Resolving Spontaneously? What Does Literature Say About Time Frames, Conservative Measures Etc?

The odds of resolution are good. Continue with gentle upward massage, and as long as your eye is protected and moist, time is on your side. This is more common when the cheek is behind the front of the eye, when large amounts of fat are removed and less commonly when too much skin is removed.

The fact that you can easily push the eyelid up to, or even past its ideal position is a good sign. Your surgeon, obviously has the best information on prognosis.

It depends what the problem is and how bad.  For the most part, eyelid is resilient and recovers after few weeks to month, especially if first ever surgery on it.  There are things to do to help the eyelid recover in the meantime.  It is also important to lubricate your eyes. Discuss with you surgeon and consider seeing an oculoplastic surgeon if the problem persists.

It is very common for the eyelid to pull away just after surgery, and usually this will resolve within 3-4 weeks (if not sooner). Even a small amount of swelling in the lid or the conjunctiva (lining of the eyeball) can make the eyelid look pushed away. Massage will help in about 70-80% of cases and carries minimal risk. For the few cases that do not resolve on their own in that time period, steroid injections may help. Surgery is needed in a few cases, but it's best to wait as long as possible (at least 6 months) because operating sooner could cause even more scar tissue to develop, which may pull the eyelid even more.

In the meantime, make sure your eyes are protected by using drops in the day and ointment or taping at night to prevent excess dryness, which can cause damage to the cornea.
