Our capsular tension ring CTR 13/11 made from PMMA features good stability and elasticity enabled by its oval cross section design. The diameter varies between 10.5 mm in compressed and 13.0 mm in released condition. It has 2 positioning holes and is implantable by forceps or injector.
The KMR 12 combines a regular capsular tension ring with the additional function of measuring the capsular bag diameter intra- and/or post-operatively. Therefore it is primarily used for study purposes to evaluate capsular shrinkage. Diameters in a range from 8.5 to 12.0 mm can be measured.
