To investigate the efficacy and safety of implantation of an iris-claw phakic intraocular lens (PIOL), Artisan Myopia, in Asian eyes.
Minamiaoyama Eye Clinic, Tokyo, Japan.
Forty-four eyes of 32 Japanese patients and 1 Korean patient with high myopia had Artisan Myopia lens implantation to correct their refractive errors. Lens models, 5/8.5 or 6/8.5 (optic diameter/overall diameter), were chosen as standard lens model. A smaller lens model (5/7.5-Artisan Myopia Small) was implanted in eyes with corneal diameter less than 11.0 mm. Postoperative examinations were performed on 1 day, 1 week, 1 month, 3 months, 6 months, 1 year, and 2 years after surgery. Uncorrected visual acuity (UCVA), best corrected visual acuity (BCVA), manifest refraction, corneal endothelial cell counts, intraocular pressure, and complications were evaluated.
Artisan Myopia Small lenses were implanted in 4 eyes (9.1%) and 8.5 mm diameter lenses were implanted in 40 eyes. Preoperative UCVA (logMAR) improved from 1.57 to 0.09 at 1 month after surgery and no regression was observed thereafter. Postoperative manifest refraction was -1.02 +/- 0.87 D (-3.25 to -0.00 D), and within 1.0 D in 20 eyes (55.6%), within 2.0 D in 32 eyes (88.9%) at 1 month after surgery, and stable during the follow-up period. The final BCVA decreased 2 lines in 2 eyes (4.5%) due to progression of age-related cataract. No serious complications such as angle closure or progressive endothelial cell loss were observed.
Implantation of an Artisan iris-claw PIOL implantation may be a safe and effective procedure for Asian eyes.
研究虹膜夹型有晶状体眼人工晶状体（PIOL）Artisan Myopia在亚洲人眼中植入的有效性和安全性。
日本东京南青山眼科诊所。
32名日本患者和1名韩国高度近视患者的44只眼睛接受了Artisan Myopia晶状体植入以矫正屈光不正。选择5/8.5或6/8.5（光学直径/总直径）的晶状体型号作为标准晶状体型号。角膜直径小于11.0 mm的眼睛植入较小的晶状体型号（5/7.5-Artisan Myopia Small）。术后分别于术后1天、1周、1个月、3个月、6个月、1年和2年进行检查。评估裸眼视力（UCVA）、最佳矫正视力（BCVA）、显验光、角膜内皮细胞计数、眼压和并发症。
4只眼睛（9.1%）植入了Artisan Myopia Small晶状体，40只眼睛植入了直径8.5 mm的晶状体。术前UCVA（logMAR）在术后1个月从1.57提高到0.09，此后未观察到视力回退。术后显验光为-1.02±0.87 D（-3.25至-0.00 D），术后1个月时，20只眼睛（55.6%）在1.0 D以内，32只眼睛（88.9%）在2.0 D以内，且在随访期间保持稳定。由于年龄相关性白内障进展，2只眼睛（4.5%）的最终BCVA下降了2行。未观察到诸如房角关闭或内皮细胞进行性丢失等严重并发症。
Artisan虹膜夹型PIOL植入术对于亚洲人眼可能是一种安全有效的手术。
