目的： 比较两焦点(AT LISA 809MP)和三焦点(AT LISA tri 839MP)IOL植入术后的视觉质量。

方法：回顾性研究。共收集2018-03/2019-02行超声乳化吸除术联合多焦点IOL植入术的白内障患者28例49眼。两焦点组18例30眼，年龄40～85(平均67.08±10.80)岁。三焦点组10例19眼，年龄38～79(平均62.21±14.50)岁。所有患者均行视觉质量分析系统(OQAS)、离焦曲线等检查。

结果：两焦点组近BCVA优于三焦点，三焦点组中UCVA和远BCVA均优于两焦点组(P<0.05)。三焦点组+1.5、-1.0、-1.5、-2.0、-2.5、-3.0D视力显著优于两焦点组。两组间OQAS视觉质量参数两焦点组OV 20%、OV 9%、SR均优于三焦点组(P<0.05)。

结论：两焦点和三焦点IOL植入术后均可获得良好的裸眼远和近视力，视觉质量均较高，而三焦点IOL可获得更佳的中间视力。

METHODS: Retrospective study. A total of 49 eyes of 28 patients with cataract who underwent phacoemulsification combined with multifocal IOL implantation from March 2018 to February 2019 were collected. There were 30 eyes of 18 patients in the bifocal group, aged 40-85(mean 67.08±10.80)years. The trifocal group consisted of 19 eyes of 10 patients, aged 38-79(mean 62.21±14.50)years. All patients underwent visual quality analysis system(OQAS), defocus curve and other examinations.

RESULTS: The near BCVA of the two focus groups was better than that of the three focus groups, and the medium UCVA and far BCVA of the three focus groups were better than those of the two focus groups(all P<0.05). The trifocal group had better visual acuity at +1.5, -1.0, -1.5, -2, -2.5D and -3.0D defocus than the bifocal group. OQAS visual quality parameters were better in the two-focus group than in the three-focus group in OV 20%, OV 9%, and SR(all P<0.05).

CONCLUSION: Both bifocal and trifocal IOL implantation can achieve good uncorrected and near visual acuity and high visual quality, while trifocal IOL can achieve better intermediate visual acuity.
