Physical fixation of soft intraocular lenses.

Twenty silicone lenses and seven hydrogel lenses were implanted in the bag after circular capsulotomy. After surgery the haptics were firmly fixated within the bag in all cases. Inflammation was minimal in the early postoperative period. One month after surgery the average visual acuity was 20/20 or better and the average astigmatism was less than 0.5 diopter. Neodymium:YAG laser capsulotomy was not required in any case. These soft lenses seemed to be physically fixated in the bag by capsular shrinkage. We believe that this physical fixation of soft lenses is possible only when capsular integrity is maintained.
