摘　　要：目的分析超声乳化白内障吸除联合衍射型非球面多焦点人工晶体植入术后不同时间、不同瞳孔条件下视觉质量的变化情况。方法收集2019年9月至2020年7月在我院行白内障超声乳化吸除联合Tecnis全光学面衍射型非球面多焦点人工晶体(Tecnis ZMB00 MIOL)植入术的24例患者(30只眼)的临床资料。术后1周和3个月时,检测裸眼和矫正后的远、中、近视力,3 mm、5 mm孔径下的散射光值、波前像差和调制传递函数(MTF)值。采用非参数Mann-Whitney U检验对数据行统计分析。结果术后1周和3个月裸眼和矫正的远、中、近视力比较,无统计学差异。5 mm孔径下,术后3个月散射光值、球差均低于术后1周,术后1周和3个月散射光值均大于3 mm孔径,差异均有统计学意义(均P<0.05)。5 mm孔径下,术后3个月各空间频率的MTF值显著优于术后1周,20 cpd空间频率有统计学差异(P<0.05)。结论与术后1周相比,术后3个月5 mm孔径下散射光值明显减小,球面像差明显降低,MTF值升高,说明Tecnis ZMB00 MIOL植入术后3个月夜间视觉质量较术后1周有提高的趋势。Objective To compare the visual performance after implantation of diffractive aspherical multifocal intraocular lens(MIOL)under different pupil sizes(Tecnis ZMB00 MIOL).Methods In a prospective study,Tecnis ZMB00 MIOLs were implanted in 24 patients(30 eyes).The visual acuity(VA)at different distances,straylight values under 3 mm and 5 mm apertures,wavefront aberrations,and modulate transfer functions(MTF)with 3 mm and 5 mm pupil diameter were assessed 1 week and 3 months after surgery.A Mann-Whitney U test was used to compare the VA between the time-points.Results There was no statistically significant difference in the VA at different distances between 1 week and 3 months following surgery.The straylight parameters were greater under 5 mm aperture than under 3 mm aperture at both 1 week and 3 months following surgery(P<0.05).The spherical aberrations with 5 mm pupil diameter were significantly smaller at 3 months than at 1 week(P<0.05).The MTF had greater improvement at 3 months after surgery than at 1 week following surgery in almost all spatial frequencies.The differences in 20 cpd were statistically significant(P<0.05).Conclusion There are lower straylight values,lower spherical aberrations,and better MTF parameters with 5 mm pupil size at 3 months than at 1 week following surgery.The visual quality under low-illuminance conditions improves over time after Tecnis ZMB00 MIOLs implantation.
