硬性和可折叠前虹膜固定人工晶状体植入治疗亚洲眼高度近视的疗效比较

目的：比较Artisan和Artiflex有晶状体眼人工晶状体(PIOL)矫正亚洲人群高度近视的屈光度和安全性。

方法：历史队列研究。回顾2016/2020在印度尼西亚日惹市Yap眼科医院接受PIOL植入术的81例高度近视眼。根据植入PIOL分为Artisan组43眼,Artiflex组38眼。分别记录术前及术后1d、1、3mo的视力、角膜生物显微镜参数和眼压,包括术前前房深度。

结果：Artisan和Artiflex组的平均随访时间分别为9.64±6.93mo和8.96±4.28mo(P=0.736)。Artisan组的疗效指数为1.03±0.47,Artiflex组为1.02±0.17(P=0.119); 安全性指数分别为1.10±0.45和1.05±0.21(P<0.001)。Artisan组的平均等效球镜度(SE)为-0.64±0.996D,Artiflex组为-0.22±0.58D(P=0.076)。两组术后内皮细胞密度(ECD)较术前均显著下降(P<0.05),累积ECD缺失率为7.44%和5.79%(P=0.418)。

结论：Artisan和Artiflex矫正亚洲人高度近视的屈光效果相当。与Artiflex相比,Artisan的安全指数略高,而两组的疗效指数和累积ECD缺失率相似。

Efficacy comparison between rigid and foldable anterior iris-fixated phakic intraocular lens implantation for treating high myopia in Asian eyes

AIM:To compare refractive and safety outcome of Artisan and Artiflex phakic intraocular lens(PIOL)for the correction of high myopia in Asian population.

METHODS:Historical cohort study. A total of 81 high myopic eyes that underwent PIOL implantation from 2016 to 2020 at Yap Eye Hospital in Yogyakarta, Indonesia were reviewed. The patients were divided into two groups based on PIOL implanted, with 43 eyes using Artisan PIOL in Artisan group and 38 eyes using Artiflex PIOL in Artiflex group. Visual acuity, corneal biomicroscopy parameters, and intraocular pressure(IOP)were respectively recorded prior to the implantation and at 1d, 1 and 3mo after surgery. In addition, anterior chamber depth was documented before PIOL implantation.

RESULTS:Mean follow-up period were 9.64±6.93mo and 8.96±4.28mo in Artisan an Artiflex group, respectively(P=0.736). The efficacy index was 1.03±0.47 in Artisan group, and 1.02±0.17 in the Artiflex group(P=0.119).The safety index was 1.10±0.45 and 1.05±0.21 in Artisan and Artiflex group, respectively(P<0.001). The mean spherical equivalent(SE)in Artisan group was -0.64±0.996D, and it was -0.22±0.58D in Artiflex group(P=0.076). In both groups, there was a significant loss of endothelial cell density(ECD)postoperatively compare to baseline(P<0.05), and the cumulative ECD loss was 7.44% and 5.79% in the Artisan and Artiflex groups, respectively(P=0.418).

CONCLUSION:Artisan and Artiflex are comparable in terms of refractive outcome to correct high myopia in Asian eyes. Artisan had a slightly better safety index compare to Artiflex. However, the efficacy index and cumulative ECD loss was similar in both the Artisan and Artiflex groups.
