Dry, irritated eyes after facelift. I am five weeks out from a SMAS facelift. Advice? (photos)

Dryness of the eyes is not common after facelift without blepharoplasty.  If you have had some degree of facial nerve weakness in association with your surgery, this could interfere with eyelid closure and subsequent dryness.  However, since this isn't mentioned in your question, I recommend further discussions with your Surgeon and a referral to an Ophthalmologist for further evaluation. 

Dry eyes can occur following a facelift without a concomitant blepharoplasty.  It is usually due to lower lid malposition due the healing or scarring pulling down on the lower lid, particularly if skin undermining was extensive.  This results in incomplete eyelid closure and resultant dryness.  Based on your photos you appear to have a bit of lateral lower lid descent. Follow up with your surgeon to discuss interventions.  This problem usually resolves , but may take months.  regards.
