Surgical outcomes of modified capsular tension ring and intraocular lens implantation in Marfan syndrome with ectopia lentis

Abstract

Objective: To evaluate surgical outcomes of modified capsular tension ring (MCTR) and intraocular lens (IOL) implantation in eyes of Marfan syndrome (MFS). Methods: This retrospective case series included MFS patients receiving MCTR transscleral fixation and IOL in-the-bag implantation. The MCTR was sutured to the sclera through a sulcus by 9–0 polypropylene with the modified knotless Z-suture technique. Main outcomes were visual acuity and postoperative complications. Results: A total of 109 MFS patients (187 eyes) had the surgery. Patients were 15.47 ± 14.36 years old and followed up for 10.07 ± 8.99 months. MCTR and IOL implantations were performed in 174 eyes (93.05%). The postoperative BCVA (LogMAR) was 0.24 ± 0.24 (1 month), 0.26 ± 0.20 (3 months), 0.22 ± 0.20 (6 months), 0.20 ± 0.19 (12 months) and 0.25 ± 0.32 (over 12 months), which was significantly better than preoperatively (0.63 ± 0.35) ( p < 0.001). Major complications included posterior capsular opacification (PCO) in 41 eyes (23.56%) and decentered anterior capsular opacification (ACO) in 15 eyes (8.62%). The mean occurrence time was 9.44 ± 7.08 and 8.87 ± 15.08 months respectively. Other complications included transient intraocular pressure elevation in seven eyes (4.02%), retinal detachment in two eyes (1.15%), cystoid macula edema in one eye (0.57%), and endophthalmitis in one eye (0.57%). No eye had suture breakage or IOL dislocation. Conclusions: The visual improvement is significant in eyes of MFS undergoing MCTR transscleral fixation and IOL in-the-bag implantation. The long-term monitoring of complications is warranted, especially in the first-two years.
