Capsular Tension Rings With Coloboma-Correcting Segments—Less Stress With the Right Procedure for Implantation
Purpose
The aim of our study was to investigate the order of implantation of a capsular tension ring (CTR) with (a) inserting iris segments first or (b) ring segment(s) first to minimize possible risk factors for capsular rupture.
Methods
Case series; so far 21 patients are enrolled in the current study.
Results
The artificial iris segments show good capability to compensate for iris defects. According to our experience the correct order of implantation is crucial for a successful implantation: The ring segment has to be implanted first, followed by the iris segment part of the device. Implanting it the other way around the procedure is more difficult with higher risk of capsular bag damage. For a safe implantation it is very important to use adequate viscoelastics (OVD).
Conclusion
Implanting the CTR with the ring segment first and using sufficient OVD will lead to a safe and uneventful procedure rather than starting the implantation with the iris segment part of the CTR.
