To evaluate the long-term (8-10 years) outcomes of toric implantable collamer lens (TICL) surgery.

Retrospective observational study.
Patients who underwent TICL surgery from 2005 to 2009 to correct myopia and myopic astigmatism were enrolled. The safety, efficacy, predictability, astigmatism correction efficacy, and complications were evaluated using preoperative, 1-year postoperative, and final examination data.
133 eyes of 77 patients were included. At the final visit, the mean uncorrected and corrected visual acuities were -0.01 ± 0.2 and -0.17 ± 0.05, respectively. The mean safety and efficacy indices were 0.91 ± 0.26 and 0.68 ± 0.21, respectively. The manifest astigmatism was -0.45 ± 0.43 diopters (D). The mean corneal astigmatism change from 1 year postoperatively to the final visit was 0.40 ± 0.26 D. Of the 38 eyes with a change in corneal astigmatism ≥0.5 D, 30 eyes (78.9%) changed to against-the-rule (ATR) astigmatism, 1 (2.6%) changed to oblique astigmatism, and 7 (18.4%) changed to with-the-rule (WTR) astigmatism. The mean manifest astigmatism change from 1 year postoperatively to the final visit was 0.43 ± 0.52 D. Of the 60 eyes with a change in manifest astigmatism ≥0.5 D, 25 (41.7%) changed to ATR astigmatism, 18 (30.0%) changed to oblique astigmatism, and 17 (28.3%) changed to WTR astigmatism. During follow-up, 8 (6.0%) of 133 eyes developed anterior subcapsular cataracts, among which 4 (3.0%) underwent TICL removal and phacoemulsification and aspiration. No vision-threatening complications occurred.
TICL surgery showed good long-term astigmatism-correcting effects, although the long-term uncorrected visual acuity decreased. The procedure was effective in correcting myopia and astigmatism.
评估 toric 可植入式隐形眼镜（TICL）手术的长期（8-10 年）疗效。

回顾性观察研究。
招募了 2005 年至 2009 年期间因近视和近视散光行 TICL 手术的患者。使用术前、术后 1 年和最终检查数据评估安全性、有效性、可预测性、散光矫正效果和并发症。
77 例患者的 133 只眼纳入研究。末次随访时，未矫正和矫正视力分别为-0.01±0.2 和-0.17±0.05。平均安全性和有效性指数分别为 0.91±0.26 和 0.68±0.21。显斜视度为-0.45±0.43 屈光度（D）。从术后 1 年到末次随访时角膜散光的平均变化为 0.40±0.26 D。在角膜散光变化≥0.5 D 的 38 只眼中，30 只（78.9%）转变为逆规散光，1 只（2.6%）转变为斜轴散光，7 只（18.4%）转变为顺规散光。从术后 1 年到末次随访时的平均显斜视度变化为 0.43±0.52 D。在显斜视度变化≥0.5 D 的 60 只眼中，25 只（41.7%）转变为逆规散光，18 只（30.0%）转变为斜轴散光，17 只（28.3%）转变为顺规散光。随访期间，133 只眼中有 8 只（6.0%）发生前囊下白内障，其中 4 只（3.0%）行 TICL 取出联合超声乳化术。无视力威胁性并发症发生。
TICL 手术长期疗效良好，可有效矫正近视和散光，但长期未矫正视力下降。
