To evaluate the outcomes of implantation of a Cionni modified capsular tension ring (CTR) and a posterior chamber intraocular lens (PC IOL) in patients with traumatic cataract and loss of zonular support.

Case series.
Eyes with traumatic cataract and loss of zonular support had phacoemulsification with implantation of a foldable IOL and a 1- or 2-eyelet modified CTR. Preoperative features, preoperative and postoperative corrected distance visual acuity (CDVA), intraoperative performance, IOL position, and complications were evaluated.
The study enrolled 16 eyes (16 patients). The mean CDVA was 0.89 logMAR ± 0.41 (SD) preoperatively and 0.33 ± 0.43 logMAR at the last postoperative examination (P=.001). Postoperatively, the mean spherical equivalent was -0.23 diopter (D) (range -1.50 to +1.00 D) and the mean postoperative astigmatism, 1.59 D (range 0.50 to 4.00 D). Eight eyes (50.0%) had phacodonesis preoperatively; no eye had pseudophacodonesis postoperatively. Preoperatively, 10 eyes (62.5%) had symptomatic decentration. Two eyes (12.5%) had asymptomatic nonprogressive decentration in the early postoperative period; no eye had symptomatic decentration throughout the follow-up. Three eyes (18.8%) preoperatively and 1 eye (6.2%) postoperatively had vitreous in the anterior chamber. Four eyes (25.0%) required anterior vitrectomy. Other complications were symptomatic posterior capsule opacification in 8 eyes (50.0%) and transient increased intraocular pressure in 2 eyes (12.5%).
The use of a modified CTR preserved the capsular bag and resulted in good PC IOL centration with few significant complications in patients with traumatic cataract and loss of zonular support.

病例系列。
对伴有外伤性白内障伴悬韧带丧失的患眼行白内障超声乳化术，植入折叠式人工晶状体和单或双袢改良 CTR。评估术前特征、术前和术后矫正远视力（CDVA）、术中表现、IOL 位置和并发症。
本研究纳入 16 只眼（16 例患者）。术前平均 CDVA 为 0.89 logMAR ± 0.41（SD），末次随访时为 0.33 ± 0.43 logMAR（P=.001）。术后平均等效球镜为-0.23 屈光度（D）（范围-1.50 至+1.00 D），平均术后散光为 1.59 D（范围 0.50 至 4.00 D）。术前 8 只眼（50.0%）有白内障后囊下混浊；术后无一例发生假性白内障后囊下混浊。术前，10 只眼（62.5%）有晶状体明显偏心；术后早期有 2 只眼（12.5%）无症状、非进行性晶状体偏心，整个随访过程中无一例有症状性晶状体偏心。术前 3 只眼（18.8%）和术后 1 只眼（6.2%）有前房玻璃体。4 只眼（25.0%）需要行前段玻璃体切除术。其他并发症包括 8 只眼（50.0%）有症状性后囊膜混浊和 2 只眼（12.5%）有短暂性高眼压。
在伴有外伤性白内障伴悬韧带丧失的患者中，使用改良 CTR 保持了囊袋的完整性，使 PC IOL 获得了良好的中心定位，且并发症较少。
