To assess the clinical outcomes of the Visian Implantable Collamer Lens (ICL) with a central port throughout 7 years of follow-up. Eighty-four eyes of 52 patients were evaluated over a follow-up period of 7 years after V4c ICL implantation. Uncorrected (UDVA) and corrected (CDVA) distance visual acuities, refraction, intraocular pressure (IOP), endothelial cell density (ECD) and vault were analysed. The mean postoperative UDVA (logMAR) was 0.04 ± 0.11, 0.13 ± 0.19 and 0.17 ± 0.23 at 1-, 5- and 7-years, respectively (P < 0.0001). The mean CDVA (logMAR) remains unchanged throughout a 7-year follow-up period (0.02 ± 0.08 and 0.02 ± 0.08, at 5- and 7-years, respectively, P = 0.2). At all follow-up visits, more than 95% of the eyes achieved a CDVA of 20/25 or better and more than 85% a CDVA of 20/20. At the end of the follow-up (7 years), no eye lost more lines of CDVA, 56 eyes (66.7%) and 28 eyes (33.3%) gained lines of CDVA. At 7-years, the spherical equivalent was − 0.62 ± 0.62 D. No significant increase in IOP (> 20 mmHg or an increase higher than 5 mmHg) occurred in any case throughout the 7-year of follow-up. The loss in ECD from the preoperative baseline at the last follow-up visit was 2.6%. No intraoperative or postoperative complications or adverse events occurred during the follow-up period. The outcomes of this study show the long-term viability of the V4c ICL implantation as a surgical option for the correction of myopia.

中心孔设计的后房有晶状体人工晶状体的 7 年随访

评估具有中央端口的 Visian 植入式准直镜 (ICL) 在 7 年的随访中的临床结果。在 V4c ICL 植入后 7 年的随访期内,对 52 名患者的 84 只眼进行了评估。分析了未矫正 (UDVA) 和矫正 (CDVA) 远距离视力、屈光度、眼内压 (IOP)、内皮细胞密度 (ECD) 和穹窿。术后 1、5 和 7 年的平均术后 UDVA (logMAR) 分别为 0.04 ± 0.11、0.13 ± 0.19 和 0.17 ± 0.23 (P < 0.0001)。平均 CDVA (logMAR) 在整个 7 年随访期间保持不变(分别为 0.02 ± 0.08 和 0.02 ± 0.08,分别在 5 年和 7 年,P = 0.2)。在所有随访中,超过 95% 的眼睛达到 20/25 或更高的 CDVA,超过 85% 的 CDVA 达到 20/20。在随访结束时(7 年),没有一只眼失去更多的 CDVA 线,56 只眼(66.7%)和 28 只眼(33.3%)获得了 CDVA 线。在 7 年时,等效球镜为 − 0.62 ± 0.62 D。在整个 7 年的随访期间,任何情况下眼压都没有显着增加(> 20 mmHg 或增加高于 5 mmHg)。在最后一次随访时,ECD 相对于术前基线的损失为 2.6%。随访期间未发生术中或术后并发症或不良事件。这项研究的结果表明 V4c ICL 植入术作为矫正近视的手术选择具有长期可行性。在整个 7 年的随访期间,任何情况下都发生了 20 mmHg 或高于 5 mmHg 的增加。在最后一次随访时,ECD 相对于术前基线的损失为 2.6%。随访期间未发生术中或术后并发症或不良事件。这项研究的结果表明 V4c ICL 植入术作为矫正近视的手术选择具有长期可行性。在整个 7 年的随访期间,任何情况下都发生了 20 mmHg 或高于 5 mmHg 的增加。在最后一次随访时,ECD 相对于术前基线的损失为 2.6%。随访期间未发生术中或术后并发症或不良事件。这项研究的结果表明 V4c ICL 植入术作为矫正近视的手术选择具有长期可行性。
