PURPOSE: To quantify the dynamics of capsular bag shrinkage after @entity231 surgery. SETTING: University Eye Hospital, Vienna, Austria. METHODS: Nineteen eyes in 13 @entity1 had clear corneal @entity231 surgery with implantation of a foldable, open-loop, @entity1346 posterior chamber intraocular lens (IOL) (AMO SI-30). At the same time, an open, @entity4625 capsule tension ring (Morcher type 14 or 14A) was inserted to allow measurement of capsular bag circumference and diameter. After surgery, capsular bag shrinkage was quantified by measuring @entity8707 ( @entity8707 ), @entity1539 ( @entity1539 ), and distance between the eyelets of the capsule tension ring using optical methods. Capsular bag circumference (CBC) was deduced from these measurements, which were taken 1 day (baseline), 1 week, and 1 and 3 months postoperatively. RESULTS: Between 1 day and 3 months, all three parameters decreased significantly. During the first postoperative week, @entity8707 and @entity1539 did not change, while both parameters decreased between 1 week and 1 month. After 1 month, @entity8707 did not decrease further; @entity1539 continued to decrease. The CBC decreased during the entire postoperative period. CONCLUSION: Besides @entity8707 and @entity1539 , CBC significantly decreased during the first 3 months after @entity231 surgery with in-the-bag posterior chamber IOL implantation. The CBC can be calculated from the distance between the ends of the capsule tension ring, which can be measured gonioscopically. From this, the diameter of the capsular bag can be calculated in the living eye. The influence of the capsule tension ring itself on capsular bag shrinkage remains to be established.
