The faden operation, also termed posterior fixation suture, is used to weaken the rotational force of a rectus muscle when the eye rotates toward the faden muscle. Faden is the German word for suture, so it is inappropriate to call the procedure “faden suture” (i.e., suture-suture). In general, I rarely use the faden except for reducing incomitance by enhancing a recession of the medial and inferior rectus muscles.
