We appear at the present to have fallen on times in which it has become fashionable to propose at short succeeding intervals new methods for extraction of cataract, most of them slight modifications of previously existing methods; in fact, modifications so insignificant that to call them new would seem to border on absurdity. The query very naturally arises: Have we not at the present time statistics sufficient to enable us to determine with some accuracy certain great principles to guard us in our choice of an operation ? In the first place, what incision has shown itself in the greatest number of respects the best adapted for cataract extraction ? Statistics most favorable point to the Linear incision as giving the highest average of successful results. Shall the incision be in the cornea or sclerotic, or in both, at their juncture? Statistics would indicate that the incision should be made so far peripherical as it can be made, without risking involvement of the ciliary bodies, or loss of vitreous humor; Avhile the centre of the incision should as closely as possible form a tangent to the corneal border. The value of iridectomy in lessening the danger of subsequent in- flammatory reaction has also been clearly proven; and this fact alone would exclude from the list of otherwise meritorious methods of operation—a great number—such as the flap operation without iridec- tomy, the Liebreich operation, the Lebrun operation where iridectomy is but imperfectly performed, and a host of others too numerous to enumerate. It still remains, as most desirable, the discovery of some method of extracting the capsule with the lens, without materially increasing the danger of the operation. I think it quite safe to assert that at the present time the Graefe linear extraction method, with some slight modifications, is regarded 4 as the one combining the greatest number of advantages, and that the measure of success obtained by it compares most favorably with other methods. In the statistics of forty extraction operations, collected in this paper, it will be noted that four distinct methods of operation have been employed, namely : 1. Twenty-seven extractions were made by th£ Graefe linear me- thod, upward section, slightly modified. In these cases the puncture and counter-puncture were made at a distance of 1.5 mm. from the cornea, and 2 mm. below a tangent to the corneal border at its superior margin, but with the centre of the cut a tangent to the cornea, at its superior margin. This lessens materially the risk of vitreous humor loss, by rupture of the zonula at the moment of the lens exit, while at the same time the risk of corneal suppuration is not increased. Ist Method. 2. In opening of the capsule with the C3rstitome the laceration was made by three incisions, freely separating a triangular piece of the anterior capsule so as to lessen the necessity for secondary operations. In a great many cases this object was successfully attained as this portion of the capsule was removed at the moment of the lens delivery. 3. In a number of cases when the patient showed a quiet demeanor, the fixation forceps was removed after the capsule laceration, and before the lens delivery, so as to reduce to a minimum the pressure exerted on the eyeball at this critical moment. The entire number of these extractions was successful. 2d Method—The Lebrun operation. Three extractions, with good results. 3d Method. This may be called a modified flap extraction. The puncture and counter-puncture were made at a distance of 0.5 mm. from corneal border, and 3 mm. below a tangent to the superior margin of the corneal border, with centre of cut a tangent to corneal border at its upper margin; the purpose being to still further lessen the risk of involvement of the ciliary border and loss of vitreous humor, while the danger to the cornea was not proportion ably in- creased. The other steps of the operation remained unchanged. Seven cases were operated on by this method, with a resultant of five successful and two failures. 4th Method. The Liebrich extraction (downward). Three extrac- tions were made by this plan, with suceessful results.

Entire evacuation of contents of eyeball occurred in one case. The patient was a feeble old woman. Previous careful examination led to the conclusion that the cataract was one of hard nucleus and soft cortical substance. Light perception, and projection good—so that I did not apprehend such a termination. The operation was the modified flap, and while preparing to open the capsule, the sudden escape of vitreous took place, although the eyeball was entirely at rest, the fixation forceps having been previously removed, and the cystotome had not been used. Entire evacuation of the eyeball contents occurred, with subsequent severe hemorrhage. Fortunately these cases are rare. 4. Hemorrhage into anterior chamber in one case, which greatly impeded operation. 3. Escape of lens during vomiting, produced by ether, Complications during the Healing Process 1. Hemorrhage into anterior chamber in one case (Graefe), three days after the operation, caused by the finger of the patient, while asleep, being rudely thrust against the eyeball; no serious con- sequence followed, the blood being quickly absorbed. 2. Prolapse of iris, in one case. 3. Iritis simplex, in two cases. 4, Pupillary membrane, in seven cases 5. Panophthalmitis, in one case, in which evacuation of the eye- ball contents occurred. 6. Purulent capsulitis, in one case (flap). I am convinced, that, in the Graefe extraction, with some slight modifications, we have the operation combining the greatest number of important and well-settled principles, and increased dexterity in its performance will repay the surgeon and patient much more amply than the incessant striving after other methods, whose greatest merit is their novelty!
