目的：评价基于个体瞳孔直径的非球面人工晶状体（iol）在白内障手术中校正球差的可行性。单位：日本东京庆应义塾大学医院。方法：本前瞻性研究将接受白内障手术的眼根据人工晶状体类型分为4组：非球面SN （AcrySof SN60WF）、非球面ZA （Tecnis ZA9003）、非球面PY （Hoya PY-60 AD）和球形（AcrySof Natural SWAT）。测定角膜和全眼高阶像差（HOAs）及光、介视条件下的瞳孔直径。使用个体瞳孔直径计算HOA。评估角膜、眼球球差和瞳孔直径的相关性。结果：每组30只眼。非球面SN组、非球面ZA组和非球面PY组在中聚光条件下的眼球像差明显低于角膜球像差(P
PURPOSE: To evaluate the feasibility of correcting spherical aberration with aspheric intraocular lenses (IOLs) in cataract surgery based on individual pupil diameter.SETTING: Keio University Hospital, Tokyo, Japan.METHODS: In this prospective study, eyes having cataract surgery were divided into 4 groups based on IOL type: aspheric SN (AcrySof SN60WF), aspheric ZA (Tecnis ZA9003), aspheric PY (Hoya PY-60 AD), and spherical (AcrySof Natural SWAT). Postoperative higher-order aberrations (HOAs) of the cornea and whole eye and the pupil diameter under photopic and mesopic conditions were measured. The HOA was calculated using the individual pupil diameter. The correlation between corneal and ocular spherical aberrations and pupil diameter was evaluated.RESULTS: Each group comprised 30 eyes. Ocular spherical aberrations were significantly lower than corneal spherical aberrations under mesopic conditions in the aspheric SN group, the aspheric ZA group, and the aspheric PY group (P
