目得：评估白内障手术后自然瞳孔条件下球差对视功能的影响。地点：日本东京庆应义塾大学医院。方法：本研究包括接受白内障摘除并植入丙烯酸人工透镜的白内障患者。术后1个月测量术前、术后视力、全眼高阶像差、对比敏感度、明视和中间视瞳孔直径。根据对数对比敏感度函数（AULCSF）和球面像差对应于个体瞳孔直径下明视和中间视觉conditions.RESULTS：107眼79例患者（30名男性，49名女性，平均年龄68.0岁+/- 9.6 [SD]）进行了评价。明视条件下的平均瞳孔直径为2.9 +/- 0.50 mm，中间视条件下的平均瞳孔直径为3.6 +/- 0.57 mm。明视条件下的平均球面像差为0.03 +/- 0.04 pm（范围-0.12至0.34 μ m），中间视条件下的平均球面像差为0.05 +/- 0.10 μ m（范围-0.14至0.55 μ m）。明视条件下无眩光的术后AULCSF与球面像差呈显著负相关（P = 0.014）。术后有眩光和无眩光条件下的AULCSF与球差呈显著负相关（P
PURPOSE: To evaluate the effect of spherical aberration on visual function under natural pupil conditions after cataract surgery.SETTING: Keio University Hospital, Tokyo, Japan.METHODS: This study comprised cataract patients who had cataract extraction with implantation of an acrylic intraocular lens. Preoperative and postoperative visual acuity, higher-order aberration in the whole eye, contrast sensitivity function, and pupil diameter under photopic and mesopic conditions 1 month after surgery were measured. The area under log contrast sensitivity function (AULCSF) and spherical aberration corresponding to the individual pupil diameter under photopic and mesopic conditions were evaluated.RESULTS: One hundred seven eyes of 79 patients (30 men, 49 women; mean age 68.0 years +/- 9.6 [SD]) were evaluated. The mean pupil diameter was 2.9 +/- 0.50 mm under photopic conditions and 3.6 +/- 0.57 mm under mesopic conditions. The mean spherical aberration was 0.03 +/- 0.04 pm (range -0.12 to 0.34 mu m) under photopic conditions and 0.05 +/- 0.10 mu m (range -0.14 to 0.55 mu m) under mesopic conditions. The postoperative AULCSF without glare under photopic conditions was significantly negatively correlated with spherical aberration (P = .014). The postoperative AULCSF with and without glare under mesopic conditions was significantly negatively correlated with spherical aberration (P
