Abstract

Refractive anomalies are among the leading ocular conditions affecting the working-age population. One of them - high myopia - can cause severe and irreversible ocular changes, resulting in significant visual impairment or loss.

Purpose: This study evaluated changes in vault height of phakic intraocular lenses (PIOL) and intraocular pressure (IOP) following the implantation of the ICL V5 (VICM5) lens in patients with high myopia.

Material and method: The study included 60 patients. They were monitored for at least 24 months. Observation included measurement of clinical refraction, uncorrected visual acuity (UCVA), IOP, and the distance between the posterior surface of the optical part of the lens and the anterior surface of the crystalline lens (vault).

Results: All surgeries were completed without complications. The safety and efficacy indices were 1.43 and 1.34, respectively. In 97 eyes (86%) with high myopia UCVA was equal to or better than preoperative values. The mean preoperative spherical equivalent was -10.59±3.4 D, which improved postoperatively to -0.5±0.75 D. Subsequently, the spherical equivalent remained within ±0.5 D in 89% of patients. The mean postoperative IOP was 15.86±3.30 mm Hg over the course of the 24-month follow-up. One month post-implantation, the vault height of the spherical lens ICL was 469.3±134.4 µm and 432.6±124.5 µm after 24 months (p<0.001).

Conclusion: Implantation of the Visian ICL V5 lens is a safe and effective alternative refractive surgery method for the correction of high myopia.

屈光异常是影响劳动适龄人口的主要眼部疾病之一。目的：本研究评估了高度近视患者在植入 ICL V5 (VICM5) 镜片后，相控人工晶体穹窿高度（PIOL）和眼压（IOP）的变化：研究包括 60 名患者。材料：研究包括 60 名患者，对他们进行了至少 24 个月的监测。观察包括测量临床屈光度、未矫正视力（UCVA）、眼压以及晶状体光学部分后表面与晶状体前表面（穹窿）之间的距离：所有手术均顺利完成，无并发症。安全性和有效性指数分别为 1.43 和 1.34。97只高度近视眼（86%）的UCVA等于或优于术前数值。术前球面等效视力平均值为-10.59±3.4 D，术后改善为-0.5±0.75 D，89%的患者术后球面等效视力保持在±0.5 D以内。在 24 个月的随访期间，术后平均眼压为 15.86±3.30 mm Hg。植入一个月后，球面透镜 ICL 的穹顶高度为 469.3±134.4 µm，24 个月后为 432.6±124.5 µm（p 结论：植入 Visian ICL V5 镜片是矫正高度近视的一种安全有效的屈光手术替代方法。
