Removing lump in upper eyelid caused by fat transfer to eyelids

there has been a lump on my left upper eyelid after the pearl fat grafting. at first my surgeon told me to wait it off, but it has been one and half years and the lump is still there. i wrote an email to my surgeon (since i am currently abroad) and he said it could be removed through surgical excision very easily. is it safe to remove the lump through surgical excision? would it cause any harm to the surrounding tissue and to my eye? thank you very much for your answers!
