摘要

目的比较高度近视眼植入术与不植入术的环形触觉人工晶状体（iol）的旋转稳定性、倾斜度和离体度。设计随机对照试验。方法对连续行眼轴长度≥26.00 mm高度近视超声乳化人工晶状体植入术的患者随机分为两组，一组接受CTR植入术，另一组不接受CTR植入术。在手术结束（EOS）、术后1天、1周、1个月和3个月测量人工晶体的轴向方向。在每次随访时进行扫描源光学相干断层扫描以评估人工晶状体的倾斜和偏移。结果CTR植入术36眼，未CTR植入术36眼。从EOS到1天（P = 0.039）和从EOS到3个月（P = 0.018），CTR组的绝对IOL旋转明显低于非CTR组。亚组分析显示CTR植入术显著降低了厚晶状体眼的IOL旋转（P = 0.041）。虽然CTR组在每次随访中均表现出略低的倾斜和分散值，但差异无统计学意义（均P < 0.05）。结论sctr植入术改善了高度近视患者环触觉人工晶状体的术后旋转稳定性，减轻了厚晶状体的影响，而对人工晶状体的倾斜和偏心无明显影响。

Effect of Capsular Tension Ring on Rotational Stability of Loop-Haptic Intraocular Lens in Highly Myopic Patients

PURPOSE

To compare the rotational stability, tilt and decentration of loop-haptic intraocular lenses (IOLs) in highly myopic patients with and without capsular tension ring (CTR) implantation.

DESIGN

Randomized controlled trial.

METHODS

Consecutive highly myopic patients (axial length ≥ 26.00 mm) scheduled to undergo phacoemulsification with loop-haptic IOL implantation were randomly assigned to receive either CTR implantation or no CTR. The axial orientation of the IOL was measured at the end of surgery (EOS), and at 1 day, 1 week, 1 month, and 3 months postoperatively. Swept-source optical coherence tomography was performed at each follow-up visit to evaluate the tilt and decentration of IOL.

RESULTS

A total of 36 eyes with CTR implantation and 36 eyes without CTR were included. Absolute IOL rotation was significantly lower in the CTR group than in the Non-CTR group from EOS to 1 day (P = .039) and from EOS to 3 months (P = .018). Subgroup analysis demonstrated that CTR implantation significantly reduced IOL rotation in eyes with thick crystalline lenses (P = .041). Although the CTR group consistently exhibited slightly lower values of tilt and decentration at each follow-up visit, the differences were not statistically significant (All P > .05).

CONCLUSIONS

CTR implantation improves the postoperative rotational stability of loop-haptic IOLs and mitigates the effect of thick crystalline lenses in highly myopic patients, while having no significant impact on IOL tilt or decentration.

期刊介绍： The American Journal of Ophthalmology is a peer-reviewed, scientific publication that welcomes the submission of original, previously unpublished manuscripts directed to ophthalmologists and visual science specialists describing clinical investigations, clinical observations, and clinically relevant laboratory investigations. Published monthly since 1884, the full text of the American Journal of Ophthalmology and supplementary material are also presented online at www.AJO.com and on ScienceDirect. The American Journal of Ophthalmology publishes Full-Length Articles, Perspectives, Editorials, Correspondences, Books Reports and Announcements. Brief Reports and Case Reports are no longer published. We recommend submitting Brief Reports and Case Reports to our companion publication, the American Journal of Ophthalmology Case Reports. Manuscripts are accepted with the understanding that they have not been and will not be published elsewhere substantially in any format, and that there are no ethical problems with the content or data collection. Authors may be requested to produce the data upon which the manuscript is based and to answer expeditiously any questions about the manuscript or its authors.
