目的：探讨散光矫正型植入性眼内接触镜(TICL)矫治高度近视并散光的安全性、有效性、稳定性。
方法：高度近视并散光的患者15例30眼接受散光矫正型眼内接触镜植入术，观察术后1，3，6，12mo时裸眼视力、矫正远视力、屈光状态、眼压、角膜内皮细胞计数及并发症情况等。
结果：术后裸眼视力均有明显提高，术后12mo裸眼视力达到1.0以上的有27眼(90%)，等效球镜±0.5D以内28眼(93%)。术后无1例矫正远视力下降1行或1行以上。术后1mo与术后12mo相比，30眼(100%)等效球镜变化均在0.5D之内。手术前后角膜内皮细胞计数比较无显著性差异(P=0.31)。术后12mo未见并发性白内障、继发性青光眼等并发症。
结论：散光矫正型植入性眼内接触镜(TICL)矫治高度近视并散光安全、有效。

[Abstract]
AIM: To evaluate the efficacy, safety and stability of toric implantable collamer lens(TICL)for patients with high myopic astigmatism.
METHODS: Totally 15 patients(30 eyes)undergoing TICL placement were included. The uncorrected visual acuity(UCVA), corrected distance visual acuity(CDVA), refraction,intraocular pressure, endothelial cell counts and complications were regularly observed on 1 month, 3, 6 and 12 months post-operation.
RESULTS: All eyes had a significant increase in UCVA. 12 months after surgery, 27 eyes(90%)achieved UCVA better than 1.0. 28 eyes(93%)had a spherical equivalent(SE)within ±0.5D. None lost one or more lines of CDVA. 30 eyes changed within ±0.5D when comparing 1 month and 12 months. Postoperative endothelial cell density did not show a significant difference from preoperative measurements(P=0.31). Complications were not found after surgery.
CONCLUSION: TICL appears to be safe and effective for correction of high myopic astigmatism.
