目的：观察白内障超声乳化术后植入AT LISA Toric 909MP(909M)散光矫正型多焦点IOL和AT TORBI 709M(709M)散光矫正型单焦点IOL术后视觉质量及患者满意度。

方法：选取2017-12/2018-12在本院行超声乳化IOL植入术合并散光大于1.0D的白内障患者40例56眼，根据患者自愿植入单焦点散光或多焦点散光IOL分为2组，909M组23例35眼，709M组17例21眼，术后随访3mo，观察术后两组视力恢复情况、离焦曲线、残余散光度数、晶状体旋转度、术后视觉质量分析及患者满意度。

结果：治疗后两组的裸眼远视力及最佳矫正远视力较术前明显改善(P<0.05)。离焦曲线显示909M组在0D和-2.5D时有两个视力峰值，在-1D有一个低的峰值。709M组仅在0D有视力峰值。909M组脱镜率为91%(21/23)，709M组的脱镜率仅为18%(3/17)。

结论：多焦点和单焦点IOL对于白内障合并散光有良好的矫正效果，旋转稳定性良好，且多焦点IOL为患者提供了良好的远近视力以及可以接受的中视力，提高了患者的脱镜率和满意度。

METHODS: Patients with age-related cataract and corneal astigmatism(>1.0D)were enrolled and accepted phacoemulsification combined with implantation of intraocular lens(IOL)in our hospital during December 2017 and December 2018. Forty cases(56 eyes)were divided into two groups according to which IOL they chose, multiple focal astigmatism(909M)group included 23 cases(35 eyes), single focal astigmatism(709M)group included 17 cases(21 eyes). Three months postoperatively, the visual acuity, defocus curve, residual astigmatism degree, rotational stability of the IOL, postoperative visual quality analysis and patient satisfaction were evaluated.

RESULTS: At 3mo postoperatively, uncorrected distance visual acuity(UDVA)and corrected distance acuity in the two groups were significantly improved(P<0.05). The defocus curve showed that 909M group had two visual acuity peaks at 0D and -2.5D, and a low peak at -1D, 709M group had the visual peak only at 0D. Spectacle independency was achieved by 91%(21/23)of patients in the 909M group and 18%(3/17)in the 709M group.

CONCLUSION: Both of the 909M and 709M had good correction effect for cataract combined with astigmatism. It provided better rotational stability. In addition, 909M provided excellent distance, near visual outcomes, and acceptable intermediate vision. At the same time, it improved the spectacle independency and satisfaction of cataract patients combined with astigmatism.
