Intraoperative performance and postoperative outcomes of endocapsular ring implantation in pediatric eyes.

摘要

PURPOSE: To study the intraoperative performance and postoperative outcomes of Cionni modified capsule tension ring (CTR) and intraocular lens (IOL) implantation in the capsular bag in pediatric eyes with ectopia lentis. SETTING: John A. Moran Eye Center, Salt Lake City, Utah, USA. METHODS: Thirty-five eyes (22 children) with ectopia lentis and visually significant cataract that had lens aspiration and in-the-bag implantation of single-piece AcrySof IOL and Cionni CTR were included. Single- and double-eyelet CTRs were used. The rings were sutured to the sclera using 9-0 or 10-0 polypropylene (Prolene) sutures. Preoperative and postoperative best corrected visual acuity (BCVA), intraoperative performance, IOL centration, and complications were studied. RESULTS: The mean patient age was 8.2 years +/- 5.1 (SD) and the median follow-up, 28 months. A double-eyelet CTR was implanted in 12 eyes and a single-eyelet CTR, in 23 eyes. The mean BCVA at the final follow-up (0.37 +/- 0.25 logMAR, 33 eyes) was significantly better than preoperatively (0.78 +/- 0.42 logMAR, 28 eyes) (P = .003). At the last examination, the BCVA was 20/40 or better in 16 eyes (45.7%). Three eyes (8.5%) required resuturing for IOL decentration. Nineteen eyes (54.3%) had a secondary procedure for posterior capsule opacification. Other complications included anterior capsule opacification (2.85%), cystoid macular edema (5.71%), chronic uveitis (5.71%), and vitreous prolapse (2.85%). CONCLUSION: Implantation of the Cionni CTR and single-piece AcrySof IOL in the capsular bag in pediatric eyes with subluxated lenses was safe and effective and led to a stable IOL with few significant complications.
