目的：探讨伴有悬韧带松弛的高度近视合并白内障患者行超声乳化(Phaco)联合人工晶状体(IOL)植入术中囊袋张力环(CTR)的应用效果。

方法：前瞻性研究。选取2020-04/2021-08于我院行Phaco联合IOL植入术的伴有悬韧带松弛的高度近视合并白内障患者80例80眼，采用随机数字表法分为CTR组(40例40眼，行Phaco联合CTR及IOL植入术)和对照组(40例40眼，行Phaco联合IOL植入术)。比较两组患者手术前后最佳矫正远视力(BCDVA)、前囊口面积、IOL总倾斜度、主观视觉质量。

结果：术后1、3、6mo，两组患者BCDVA均较术前改善(P<0.05)，眼压均较术前降低(P<0.05)，CTR组患者前囊口面积大于对照组，IOL总倾斜度低于对照组(P<0.001)，两组患者主观视觉质量评分均较术前升高(P<0.05)，且CTR组主观视觉质量评分高于对照组(P<0.001)。术后随访6mo内，CTR组患者术后并发症总发生率低于对照组(7.5% vs 25.0%，P<0.05)。

结论：对伴有悬韧带松弛的高度近视合并白内障，Phaco联合IOL植入术中植入CTR有助于维持囊袋形态，减少囊袋收缩，稳定IOL位置，提高术后视觉质量，且并发症少。

METHODS: Prospective study. A total of 80 patients(80 eyes)with high myopia, cataract and suspensory ligament relaxation who underwent Phaco combined with IOL implantation in the hospital between April 2020 and August 2021 were enrolled. According to random number table method, they were divided into CTR group(Phaco combined with CTR and IOL implantation)and control group(Phaco combined with IOL implantation), with 40 cases(40 eyes)in each group. The best corrected distance visual acuity(BCDVA), anterior capsule area, total IOL inclination and subjective visual quality before and after surgery were compared between the two groups.

RESULTS: At 1, 3 and 6mo after surgery, BCDVA was improved(P<0.05), and intraocular pressure was decreased in both groups(P<0.05). The anterior capsule area in CTR group was larger than that in control group, and total IOL inclination was lower than that in control group(P<0.001). After surgery, scores of subjective visual quality in both groups were increased(P<0.05), which were higher in CTR group than control group(P<0.001). Within 6mo of follow-up, total incidence of postoperative complications in CTR group was lower than that in control group(7.5% vs. 25.0%, P<0.05).

CONCLUSION: With fewer complications, the application of CTR in Phaco combined with IOL implantation is beneficial to maintain capsular morphology, reduce capsular contraction, stabilize IOL position and improve postoperative visual quality in patients with high myopia, cataract and suspensory ligament relaxation.
