目的：研究有晶状体眼后房型散光矫治型人工晶状体(toric implantable collamer lens，TICL)植入术对近视散光患者视力、轴稳定性及视觉功能的影响。
方法：选取2014-06/2015-07我院就诊的行TICL术的屈光不正患者72例90眼，术前术后分别检查裸眼视力(uncorrected visual acuity，UCVA)、最佳矫正视力(best corrected visual acuity，BCVA)、屈光度、对比敏感度，术后1wk，3、6mo通过裂隙灯测量TICL散光轴位，术后6mo调查问卷研究患者视觉功能满意度。
结果：术后1wk，3、6mo时UCVA和BCVA均明显高于术前(P<0.05)； 术后1wk，3、6mo的屈光度和散光度无统计学差异(P>0.05)； 术后1wk，3、6mo各频率段的对比敏感度均高于术前(P<0.05)； TICL轴位的变化较小，术前术后无统计学差异(P>0.05)； 患者满意度调查大于98%。
结论：TICL植入术治疗近视散光安全有效，值得推广。

[Abstract]
AIM: To study the effect of toric implantable collamer lens(TICL)implantation on axial stability and visual function of patients with myopia and astigmatism after intraocular lens implantation.
METHODS: The analysis was performed in TICL operation of 72 cases of patients with ametropic(90 eyes)in our hospital from Jun. 2014 to Jul. 2015. Uncorrected visual acuity(UCVA), best corrected visual acuity(BCVA), refraction and contrast sensitivity were evaluated before and after treatment. The TICL axis of astigmatism was measured by slit lamp from 1wk, 3mo and 6mo postoperatively. The visual function satisfaction was done by survey questionnaire study 6mo postoperatively.
RESULTS:Significant improvement in UCVA and BCVA were found at 1wk, 3mo and 6mo(P<0.05). The refraction and astigmatism at 1wk, 3mo and 6mo after treatment were no significant difference(P>0.05). The contrast sensitivity was all significantly better than results before operation(P<0.05). It indicated the better stability of axis after TICL. The proportion of visual function satisfaction of patients was over 98% postoperatively.
CONCLUSION: TICL implantation is safe and effective in the treatment of myopia and astigmatism, worthy of promotion.
