    The cataractous lenses were both extracted by upward incision and iridec- tomy. The eyes were closed in the usual manner by strips of plaster. All the dressings were removed and dark glasses used at the end of the eighth day. On the twentieth day he was ordered -f 10 D. spectacles, as the inflam- mation had not sufficiently subsided to prescribe glasses with any accuracy. A few weeks afterward I examined him again and prescribed for the right eye -j- 12 D., V. = ^ ; for the left eye + 10 D., V. = —— In both eyes XXV LXXX there was some evidence of lymph shreds in the pupillary area. With -f- 18 D. on both eyes he could read a newspaper without difficulty. Case XII. — A Frenchwoman, aged thii’ty-six, had cataract of the left eye, which was apparently soft from its color as seen through the pupil. I expected to do the suction operation, but when, in January, 1889, I split the anterior capsule with a cystotome, it became evident that the opacity was entirely in the anterior capsule, as she instantly saw the light perfectly through the slit made by the instrument. One eye only was sealed and the patient was allowed to go about her ordinary duties. The lens soon became opaque from contact with the aqueous humor. It was a number of weeks before the flocculent masses of the lens material were absorbed; during all of which time she attended to her duties. The eye, however, was kept under the influence of atropia. After a few days the plaster was taken from the eye operated upon and she simply wore dark glasses to exclude the light. On April 13th + 12 D. gave V. = — . The pupil was still dilated bv XXXVI atropia. There was a thin veil occluding the pupil, evidently opaque pos- terior capsule. As the operation was done merely to relieve the defect pro- duced by the unsightly white color of the pupil, no further attempts were made to improve the vision, as the right eye was used for all ordinary purposes. Case XIII.—January 23, 1889. Mrs. K., aged thirty-two years. Soft cataract and external strabismus in an organ defective since childhood. As the lens was soft it was sucked out in the ordinary manner by the suction apparatus. One eye alone was covered by plaster. On the seventh day she was out, and on the eighth day she came to my office with the left eye still covered. On February 10th I took the plaster off, and subsequently, when the irritation had subsided, I cut the external rectus and advanced the ten- don of the internal rectus. The irritability of the eye remained for several weeks; and when she went home there was a thin veil-like occlusion, due to the posterior capsule. The eye had never been of use, and the operation was only done for cosmetic effect; hence no useful vision was to be expected. When she went home -f 6 D. was put in front of the right eye to magnify the small palpebral opening and globe. The refraction of the other eye was corrected by a cylindrical lens.
