Sutures Not Dissolving on Upper Eyelids?

The first piece of advice I will give is : Don't worry, the sutures will be gone very soon.

The reason I prefer permanent (removable) monofilament sutures for upper eyelid surgery is that there is less initial tissue reaction than with absorbable sutures.  Although the variant of absorbable suture  probably used in your case is designed to dissolve in 6-7 days, it can last longer in certain circumstances.  At 1 year, it won't make a difference because eyelid surgery scars almost invariably heal withe minimal scarring

Your upper eyelid sutures might need removal.  Ask your surgeon.  If they are the dissolvable type, depending on the material used, it may take a bit longer for them to disappear.  I would call your surgeon and get the information.
