title: [Further studies of centering posterior chamber lenses in attempted sulcus fixation].
abstract: A total of 301 posterior chamber lenses implanted consecutively by one surgeon were examined on postoperative days 3-7 with special regard to both centering and the position of the haptics. It was possible to evaluate 296 eyes. In these, 83.1% of the lenses were ideally centered, while 16.9% were found to be slightly eccentric. There was one serious lens dislocation. The position of the haptics was evaluated in 245 eyes. The attempt to fix both haptics in the sulcus was achieved in 74.7% of the cases. Of the implants fixed in the sulcus, 96.2% were ideally centered. In the remaining cases 11 lenses were fixed entirely in the capsule but in 51 one loop was in the sulcus and the other in the capsule. While the lens is usually centered well when both loops are in the capsule (81.8%), it is significantly less well centered if one loop is fixed in the sulcus and the other in the capsule (41.2%). The data are discussed.
