One eye is more hooded and droopy than the other. What options are available to correct this?

For significant improvement, hooded eyelids require surgery if there is enough skin. For nonsurgical treatments: Radiofrequency (Thermage or Venus Legacy/Viva), injectable fillers, and a Botox brow lift can help contour the eyebrows and lift the eyelid skin. I recommend getting a formal evaluation with an experienced cosmetic dermatologist. Best, Dr. Emer.

The left eye muscle is not opening as well as the right side - this is corrected by reinserting the muscle more tightly to the lid cartilage. Your brows will descend as a result of this surgery, since your brows will not need to pull so much to help the eyes see better. The drop will occur over both eyes. Hence, the excess skin should be done on both eyes, in anticipation of the brow descent. If you like the current position of the brows, then a brow suspension will need to be performed to prevent the brow descent.

You have excess skin in both upper eyelids but more on the left.  A difference in the amount of skin in the eyelids is actually common.  Upper blepharoplasty would be done by removing more skin on the left side than the right in an effort to minimize the hooding/drooping and balance the eyelids.  You also appear to have fullness in the inner corner of the upper eyelid, particularly on the left side.  This is typically due to an overly prominent fat pad that can be reduced.
