title: [Experience with the implantation of the Choyce Mark IX anterior chamber lens].
abstract: Experience gathered so far in the implantation of the Choyce Mark IX anterior chamber lens in 140 cases is reported. The follow-up period was 1 year. The advantages of this lens compared to all other implantation lenses are its complete visibility, the fact that it is replaceable, and the ease and rapidity of implantation. The main problem lies in determining the correct length of the lens. A high percentage (56%) of distortion of the pupil has so far had no negative influence on ocular function. Hemorrhages into the chamber angle can be avoided by atraumatic surgery.
