Abstract

Purpose: This study evaluated the effectiveness of the implantable collamer lens (ICL) V4c in the surgical treatment of myopia.

Material and methods: The study analyzed the outcomes of ICL V4c implantation in 616 eyes with myopia. Visual acuity, refraction, intraocular pressure (IOP), anterior chamber angle (ACA), vault height, and corneal endothelial cell density (ECD) were evaluated. Patients were examined preoperatively and followed up for one year.

Results: Preoperative uncorrected and best-corrected visual acuity were 0.04±0.02 and 0.83±0.12, respectively, improving to 0.97±0.10 and 0.97±0.10 one year postoperatively. The efficacy index was 1.17±0.17, and the safety index was 1.18±0.18. The spherical equivalent (SE) decreased from a preoperative value of -8.79±2.62 to 0.20±0.58 D at one year (p<0.0001). The ACA decreased from 39.46±4.97° preoperatively to 22.79±4.74° at one year. Vault height was 747±280 μm on the first postoperative day and 755±285 μm at one year (p<0.72), with no tendency for reduction over time. ECD was 2784±244 cells/mm² preoperatively and 2755±254 cells/mm² at one year (p<0.29).

No significant linear regression was found between IOP, vault, and ACA.

Conclusion: In a large cohort of patients who underwent ICL V4c implantation using the standardized technique, the procedure was demonstrated to be a highly effective, safe, and predictable refractive surgery option for correction of myopia of various degrees, and helped achieve stable visual outcomes. The decrease in spatial relationships in the anterior chamber following standard ICL V4c implantation did not lead to increased IOP.

【人工晶状体矫正近视】。

目的：评价人工晶状体（ICL） V4c在近视手术治疗中的效果。材料与方法：分析616只近视眼的ICL V4c植入术效果。评估视力、屈光、眼内压（IOP）、前房角（ACA）、拱顶高度和角膜内皮细胞密度（ECD）。术前检查，随访1年。结果：术前未矫正和最佳矫正视力分别为0.04±0.02和0.83±0.12，术后1年分别改善为0.97±0.10和0.97±0.10。疗效指数为1.17±0.17，安全性指数为1.18±0.18。球形当量（SE）从术前的-8.79±2.62下降到一年后的0.20±0.58 D （ppp）。IOP、拱顶和ACA之间没有明显的线性回归。结论：在大量采用标准化技术接受ICL V4c植入术的患者中，该手术被证明是一种高度有效、安全、可预测的屈光手术，可用于矫正不同程度的近视，并有助于获得稳定的视力结果。标准ICL V4c植入后，前房空间关系的降低并未导致IOP升高。
