My left lower eye lid is pulling away from the inner corner of the eye after lower eyelid surgery.

Follow your surgeon's suggestions.  Some of these resolve without too much trouble.  Some require revisional surgery in order to improve.  Time will tell.  Consider posting photos so that we can provide more specific suggestions.

Problems with eyelid position such as pulling away from the eye or pulling down can occur to a variable degree after lower blepharoplasty especially during the first three weeks where healing and swelling are taking place. It occurs more commonly towards the outer corner of the eye. It is my opinion that when it happens that early then it is better to get it corrected instead of waiting. You may want to follow up with your surgeon soon. 

Lower eyelid retraction, ectropion and distraction can occur in the immediate post-operative period. Fortunately, most cases will improve with time. Outside the immediate post-operative period, excessive skin removal, aggressive dissection that damages the nerve supply to the orbicularis oculi muscle ( the muscle that closes the eye), or the failure to correct laxity can result in this condition. In your specific cases, it is important to make sure your eyes are protected and well lubricated. I would certainly discuss this with your surgeon. Vikram D. Durairaj, MD FACS Austin, Tx
