When there has been an old iridocyclitis with atrophic iris, and the pupil is secluded or occluded, one operation, intracapsular extraction, usually with iridectomy, is generally conceded to be the operation of choice. In the past, preliminary iridectomy followed later by extracapsular extraction has been advocated and we have been cautioned to remove the anterior capsule by twisting to tear it with toothed forceps in order to avoid traction on the ciliary processes. In this type of case the zonule is usually exceedingly friable, and, when the anterior capsule is grasped with toothed forceps, the lens often dislocates and can easily be removed in its capsule.
