Abstract
PURPOSE
To evaluate the safety and efficacy of capsular tension ring and capsular hook (CTR-CH) implantation in Marfan syndrome (MFS) patients with ectopia lentis (EL).
SETTING
Eye and ENT Hospital of Fudan University, Shanghai, China.
DESIGN
Retrospective propensity score-matched cohort study.
METHODS
This study included patients with MFS who had in-the-bag intraocular lens (IOL) implantation assisted by CTR-CH or modified CTR (MCTR). The safety analysis focused on the resurgery rate. The efficacy analysis compared the corrected distance visual acuity (CDVA) and the incidence of laser capsulotomy after propensity score matching (PSM).
RESULTS
This study encompassed 148 eyes that had the CTR-CH procedure and 162 eyes that received MCTR implantation. In the CTR-CH group, the median age at the time of surgery was 5 years, with a mean follow-up duration of 1.81 ± 0.4 years. 5 eyes (3.38%) required a second surgery because of retinal detachment (2, 1.35%), IOL decentration (2, 1.35%), and CH dislocation (1, 0.68%). The resurgery rate was comparable with that of the MCTR group ( P = .486). After PSM, a total of 108 eyes were recruited in each group. Postoperative CDVA was significantly improved in both groups (both P < .001), but comparable between the groups ( P = .057). The posterior capsular opacification took place earlier ( P = .046) while the anterior capsular opacification required laser capsulotomy at a later stage ( P = .037) compared with the MCTR group.
CONCLUSIONS
The CTR-CH procedure was a feasible, safe, and efficient approach for managing EL in patients with MFS.
