Our Capsule Tensioning Ring Application Results In Wide-Angle Zonule Dialysis Up To 180 Degrees

The purpose of this study is to present the postoperative results, surgical method, and segmental anterior capsular phimosis in wide-angle cases up to 180 degrees in which we placed the Capsule Tension Ring (CTR).

The video, surgical method, autorefractometry, visual acuity and six-month results of all six cases in our clinic were evaluated.

In three female and three male cases over 65 years of age, hand movement vision, middilated pupil and pseudoexfoliation were present. CTR was placed in three of our patients as soon as zonular dialysis was seen, and CTR was placed in our other three patients before intraocular lens insertion after phaco. Posterior capsule was intact in all cases. Cortex cleaning was performed in one patient by attaching an iris retractor to the capsule. Three-piece lenses in four patients and one-piece lenses in two patients were placed intracapsular.

In all cases, the lens was centralized, anterior camera was formed, and there was an average of two degrees of astigmatism postoperatively. The mean best corrected visual acuity of all patients after surgery was 0.7. Segmental anterior capsular phimosis developed in the quadrant of zonular dialysis in five patients at the first month follow-up. No lens decentralization was observed in our patients during follow-up. Although one of our patients had iridodonesis and a mobile iol at the end of one month, no dislocation was observed in the follow-ups.

If the posterior capsule is intact in large zonular dialysis, a modified CTR, and capsular tension segment should be inserted as the first choice. Although segmental anterior capsular phimosis developed in all cases, there was no dislocation at six-month follow-up.
