摘要:

目的 探究高度近视白内障患者行超声乳化白内障吸出联合囊袋张力环(CTR)植入术后囊袋的稳定性。方法 纳入高度近视合并白内障的患者80例(80眼),随机均分为试验组和对照组。试验组行超声乳化白内障吸出联合CTR植入治疗,对照组未联合CTR植入,其余干预完全一致。比较2组术前和术后1、3、6个月时的裸眼视力(UCVA)、远距最佳矫正视力(BCVA)、角膜生物力学、对比敏感度、人工晶状体倾斜度、术后前囊口面积,并在术后6个月统计后发性白内障(PCO)发生率。结果 2组术后1、3、6个月UCVA、BCVA均较术前改善。2组患者术后角膜生物力学参数Ambrosio水平关系厚度(ARTh)、角膜硬度参数(SP-A1)和比较差异均无统计学意义。试验组Corvis生物力学指数(CBI)在术后3个月后较对照组显著升高(P<0.05),2组间其余时间点比较差异无统计学意义。术后各时间点,2组对比敏感度比较差异无统计学意义(P>0.05);术后3个月和6个月,与对照组相比,试验组前囊口面积增大,人工晶状体植入术(IOL)倾斜角减小(P<0.05)。术后6个月时试验组未发生PCO 38眼,PCO Ⅰ级2眼;对照组未发生PCO 33眼,PCO Ⅰ级3眼,Ⅱ级2眼,Ⅲ级2眼。结论 超声乳化白内障吸出联合CTR植入治疗对高度近视白内障患者术后囊袋具有较高的稳定性,远期临床效果及视觉质量更高,值得临床推广应用。

Abstract:

Objective To investigate the stability of pouch in patients with high myopia cataract after phacoemulsification cataract extraction combined with capsular tension ring (CTR) implantation. Methods A total of 80 patients with high myopia complicated with cataract (80 eyes) were included and randomly divided into the experimental group and the control group. The experimental group received phacoemulsification cataract extraction combined with CTR implantation, while the control group was not combined with CTR implantation, and the other interventions were completely consistent. The naked eye visual acuity (UCVA), best corrected distant visual acuity (BCVA), corneal biomechanics, contrast sensitivity, intraocular lens inclination and anterior capsular opening area were compared between the two groups at 1, 3 and 6 months after surgery. The incidence of late cataract (PCO) was measured 6 months after surgery. Results UCVA and BCVA were improved at 1, 3 and 6 months after operation. There were no significant differences in postoperative corneal biomechanical parameters ARTh and SP-A between the two groups of patients (P>0.05). The Corvis biomechanical index (CBI) of the experimental group was significantly higher 3 months after surgery than that of the control group (P<0.05), and there were no significant differences at other time points between the 2 groups. There was no significant difference in contrast sensitivity at each time point after surgery between the experimental group and the control group (P>0.05). At 3 and 6 months after operation, the anterior capsule opening area was increased in the experimental group, and IOL inclination angle was decreased compared with the control group (P<0.05). At 6 months after operation, no PCO occurred in 38 eyes and PCO grade Ⅰ in 2 eyes. No PCO occurred in 35 eyes in the control group, 3 eyes in grade Ⅰ, 2 eyes in grade Ⅱ and 2 eyes in grade Ⅲ. Conclusion Phacoemulsification cataract extraction combined with CTR implantation has higher stability, long-term clinical effect and visual quality in patients with high myopia cataract, and is worthy of clinical application.
