Albucasis describes the operation in nearly the same terms as Aëtius. Thus, he directs us to pass a needle armed with a double thread, below the fleshy excrescence from the left canthus to the right, and stretching it by means of the threads to cut it out with a broad scalpel. If this incision does not relieve the eyelid, he directs us to take the specillum (radius) and applying it to the incision, to evert the eyelid with it, and then to make two incisions in the inner surface of the eyelid so that they may meet at an angle below, like the Greek letter Λ. Then this triangular portion is to be dissected out, and the edges united by a suture with a woollen thread. When the disease arises from a cicatrix he directs us to divide it, and then to keep the lips of the wound separate by the application of a pledget. He concludes with the remark that, as the disease puts on various forms, a prudent surgeon will show his skill by restoring the parts to their natural state. Haly Abbas evidently borrows his description from Aëtius or our author. The operation here described is very similar to the one practised by the late Sir William Adams. In the days of Fabricius this operation was condemned as cruel and troublesome. It will be remarked that the V operation of modern times is a modification of the operation now described. SECT. XIII.—ON ANABROCHISMUS AND BURNING WITH IRON. When the hairs which irritate the eye are not numerous, but only one, two, or at most, three, close to one another, we approve of the operation called anabrochismus. Taking, therefore, a very slender needle, we pass through its ear (eye?) a woman’s hair or a fine flaxen thread, and unite the two extremities together in such a manner that the thread or hair which is passed through may have a double loop; and we pass another such thread or hair through the loop, and pushing the needle through the tarsus where the preternatural hairs appear, we introduce the hair or hairs into the loop by means of an ear-specillum, and draw it upwards. And if the hair of the eyelash be fixed in it, we draw up the loop; but if one or more, fall out, we again, by means of the one at first introduced, draw down the loop, and once more introducing a hair or hairs, draw them upwards. But if there is only one slender hair that irritates the eye we draw up another of the ciliary hairs along with it, anointing them with gum or some other glutinous substance, and bending them until they unite to the skin. Some preferring burning to the operation of anabrochismus, turn the eyelid outwards, and with a hair-forceps dragging out the offending hair, if there is but one, or two, or three; if there be as many, they apply a double-headed specillum, or an ear-specillum, or some such small instrument heated, to the place whence the hair or hairs were removed. For the skin being thus constricted, no other hair is produced. * * * * *
