Ibn Abī Uṣaybi'a refers to cataract surgeries in the biography of Sadīd al-Dīn ibn Raqīqa (d. 1238), a court physician and an expert in the "art of ophthalmology and surgery, and in treating diseases of the eye, performing many surgical operations."

Line 24: "Now (it pains me to say) he is like a stone [or: he is a stone of the grave?]": This phrase, אבן דומה, is understood by Goitein as a reference to biblical יורדי דומה, "dead people" (Ps. 115:17).
