The distinct performance of the operation for artificial pupil, and the treatment of the lens by the absorbing process, after the lapse of an interval, is for ob- vious reasons objectionable, when it is possible to do otherwise. 8. Closed pupil and partial adhesion of the iris to. the opaque cornea. ‘The separation of the cornea and iris when in adhesion, is an attempt altogether unadvisable. It is only at that part of the transparent cornea, which is free from ad- hesion. to the iris, that the attempt to make an artificial pupil can be of any avail. ‘The re- moval of a portion of the fixed iris, by hooking it through a limited section of the cornea, for the purpose of strangulation or excision, is an operation of much delicacy. It is however in high repute with the German surgeons. If the iris is at any part rendered tense by adhesion to the cornea, an extensive vertical or oblique division of its fibres with the iris knife, or Maunoir’s scissars, is best adapted to this case. The simple incision of the iris is enough, if it
