To compare the rotational stability and visual outcomes of plate-haptic toric intraocular lenses (IOLs) with and without a capsular tension ring (CTR) in paired eyes.
Eye and Ears, Nose, and Throat Hospital of Fudan University, Shanghai, China.
Prospective, randomized, paired-eye study.
Patients with bilateral cataracts and coexisting regular corneal astigmatism were enrolled. The 2 eyes of each patient were randomly assigned to the CTR or non-CTR (NCTR) group. Both eyes of each patient were subjected to phacoemulsification and toric IOL implantation. CTRs were implanted into the eyes of the CTR group. All patients were followed up for 12 months; uncorrected distance visual acuity (UDVA), residual astigmatism (RAS), and rotational degree of the toric IOL were recorded.
186 eyes of 93 patients were eligible for analysis. At each visit, UDVA improved significantly postoperatively in all eyes ( P < .001). The mean rotational degree and RAS were significantly smaller in the CTR group at the 2-week visit ( P < .05). The toric IOLs achieved rotational stability at 1 week postoperatively in the CTR group while at 2 weeks postoperatively in the NCTR group. In the subgroup analyses, CTR coimplantation significantly reduced the 2-week IOL rotation in eyes meeting specific ocular measurements.
CTR coimplantation could increase the rotational stability of plate-haptic toric IOLs, by reducing the amount of IOL rotation in the early postoperative period and accelerating the stabilization of IOLs in the capsular bag.
比较植入和未植入囊袋张力环（CTR）的板式触觉散光人工晶状体（IOL）在双眼的旋转稳定性和视觉效果。

前瞻性、随机、双眼研究。
纳入患有双侧白内障并伴有规则角膜散光的患者。将每位患者的双眼随机分配至CTR组或非CTR（NCTR）组。对每位患者的双眼均进行超声乳化白内障吸除术和散光IOL植入术。在CTR组的眼中植入CTR。所有患者均随访12个月；记录未矫正远视力（UDVA）、残余散光（RAS）和散光IOL的旋转度数。
93例患者的186只眼符合分析条件。每次随访时，所有眼术后UDVA均显著改善（P <.001）。在术后2周时，CTR组的平均旋转度数和RAS显著较小（P <.05）。CTR组的散光IOL在术后1周达到旋转稳定，而NCTR组在术后2周达到旋转稳定。在亚组分析中，联合植入CTR可显著降低符合特定眼部测量标准的眼中IOL在术后2周时的旋转。
联合植入CTR可提高板式触觉散光IOL的旋转稳定性，通过减少术后早期IOL的旋转量并加速IOL在囊袋内稳定。
