目的：应用双通道客观视觉质量分析系统(OQSAⅡ)测量高度近视并发白内障患者植入区域折射型和衍射折射型多焦点人工晶状体(MIOL)术后的视觉质量。

方法：回顾性研究。选取2019-01/2020-01在我院诊断为高度近视并发白内障行飞秒激光辅助的白内障超声乳化吸除联合MIOL植入术的患者38例44眼。根据植入MIOL的不同分为区域折射组(19例22眼)和衍射折射组(19例22眼)。术后随访3mo，比较两组患者视力，OQASⅡ测量客观视觉质量，对患者主观视觉质量进行问卷调查，记录患者视近脱镜率、视觉干扰症状及满意度。

结果：术后3mo，两组患者裸眼远视力(UCDVA)、裸眼中视力(UCIVA)及裸眼近视力(UCNVA)无差异(P>0.05)，最佳矫正远视力(BCDVA)及该矫正状态下的中距离(BCIVA)和近距离视力(BCNVA)均无差异(P>0.05)。区域折射组和衍射折射组客观散射指数(OSI)分别是1.97±1.10和2.07±1.02(P=0.755)，MTF cut off分别为31.89±14.61和33.17±9.83c/deg(P=0.734)。两组患者OV100%、OV20%、OV9%、主观视近脱镜率、视觉干扰症状及满意度比较均无差异(均P >0.05)。

结论：高度近视并发白内障患者植入区域折射和衍射折射型MIOL术后均能够获得较好的远、中及近距离视力和视觉质量，OQASⅡ能够客观反映术后视觉质量。

METHODS: Retrospective study. From January 2019 to January 2020, 38 patients with 44 eyes diagnosed as cataract with high myopia that had underwent femtosecond laser-assisted phacoemulsification combined with intraocular lens implantation in our hospital were selected. Regional refraction MIOL group includes 19 cases 22 eyes, and diffraction refraction MIOL group includes 19 cases 22 eyes. After 3mo follow up, OQASⅡ measured objective visual quality and questionnaire surveys were conducted on the subjective visual quality of the patients. Record the patient's subjective near spectacle independence, visual disturbance symptoms, and satisfaction.

RESULTS: After 3mo follow-up, the uncorrected distance visual acuity(UCDVA), uncorrected intermediate visual acuity(UCIVA)and uncorrected near visual acuity(UCNVA)had no difference(P>0.05), and the best corrected distance visual acuity(BCDVA), best corrected intermediate visual acuity(BCIVA)and best corrected near visual acuity(BCNVA)had no difference(P>0.05). The objective scattering index(OSI)values of regional refraction MIOL group and diffraction refraction MIOL group were 1.97±1.10 and 2.07±1.02(P=0.755). The MTF cut off of regional refraction MIOL group and diffraction refraction MIOL group were 31.89±14.61 and 33.17±9.83c/deg, respectively(P=0.734). There was no statistically significant difference in OV100%, OV20%, OV9% between the two groups(all P>0.05).

CONCLUSION: Cataract patients with high myopia can obtain better distance, middle and diffraction refraction MIOL implantation, and OQASⅡ can objectively reflect the visual quality after cataract surgery.
