In one who has become emaciated from disease, therapeutic procedures, fasting, and the like, who suddenly consumes [them], / or in another who excessively indulges in heavy, sour, unctuous, and cold, / salty, alkaline, sharp, and hot [foods], vegetables, water, sleep, and waking. // Even for a confident physician who has succeeded many times in surgical operations, // That which has reached the black [pupil], covered with flesh, tendons, and veins, / elevated like torn skin, should be excised; but if it has reached the vision, one should avoid it.
