Abstract：
Background/Objectives: This retrospective case series analyzed visual outcomes in patients with a prior history of implantable collamer lens (ICL) implantation who underwent cataract extraction (CE). A secondary aim was to investigate the relationship between vault height and the rate of cataract development. Methods: Visual acuity and refraction measurements were collected after CE at one week, one month and six months. Vault height measurements were correlated to the time until symptomatic cataracts were removed. Results: A total of 44 eyes were analyzed at six months after CE with efficacy and safety indexes of 1.20 ± 1.11 and 1.50 ± 1.06, respectively. In addition, 70% of eyes had a post-operative uncorrected distance visual acuity (UDVA) within one line of pre-operative corrected distance visual acuity (CDVA). Refractive predictability at six months demonstrated that 43% and 69% of eyes were within ±0.25 D and ±0.50 D of SEQ target, respectively. Astigmatism measured by refractive cylinder was ≤0.25 D in 17% and ≤0.50 D in 34% of eyes pre-operatively compared to 40% and 60% of eyes, respectively, at six months post-operatively. Vault heights one week after ICL (p < 0.0081) and one week before CE (p < 0.0154) demonstrated a positive linear regression with the time until CE. Conclusions: This sample population achieved favorable visual outcomes six months after CE, similar to six months after ICL implantation. Patients with a history of ICL implantation will similarly have a good visual prognosis after CE.
摘要：
背景/目标：本回顾性病例系列分析了有植入式晶状体（ICL）植入史的患者接受白内障摘除（CE）的视力结果。次要目的是研究穹顶高度与白内障发展速度之间的关系。方法：在CE术后一周收集视力和屈光测量值，一个月六个月.穹顶高度测量值与消除有症状的白内障之前的时间相关。结果：CE后6个月共44只眼，疗效和安全性指标分别为1.20±1.11和1.50±1.06。此外,70％的眼睛的术后未矫正远距视力（UDVA）在一行术前矫正远距视力（CDVA）内。六个月时的屈光可预测性表明，43%和69%的眼睛在SEQtarget的±0.25D和±0.50D内，分别。屈光柱体测量的散光在17％的眼睛中≤0.25D，在34％的眼睛中≤0.50D，而在40％和60％的眼睛中，分别,术后六个月。ICL后一周（p<0.0081）和CE前一周（p<0.0154）的穹顶高度与CE之前的时间呈正线性回归。结论：该样本人群在CE后六个月取得了良好的视力结果，与ICL植入后6个月相似。具有ICL植入史的患者在CE后同样具有良好的视觉预后。
