Abstract Details

Purpose:

A disadvantage of a closed capsular tension ring is that a rigid (PMMA) closed ring would require a bigger incision, however a soft (silicone) closed ring might not provide sufficient support to the weakened zonulae. By using a super-elastic material we have been able to make a closed tension ring that provides more resistance to compression then the standard PMMA ring while allowing insertion through a 1mm incision. The purpose of this study is to demonstrate the performance of the newly developed closed capsular tension ring

Setting:

Private research setting

Methods:

Compression forces were evaluated as well as susceptibility to damage during manipulation. Insertion techniques were tested and stress on the zonulae was recorded and evaluated.

Results:

The closed capsular tension ring has shown to provide a more homogeneous 360 degree resistance to compression compared to the open ended CTR. The use of a super-elastic material allows the CTR to be inserted trough a very small incision without weakening it. The video analysis shows a reduced stress on the zonulae during insertion.

Conclusions:

The closed capsular tension ring provides a better resistance to compression then regular open ended CTRs and reduces torsional tension during insertion. By using a super-elastic material it is possible to insert a closed ring trough a very small incision.
