PURPOSE To compare the effect of intraocular lens (IOL) decentration on the optical quality in patients with implantation of three IOLs: monofocal, extended depth of focus (EDOF), and bifocal. METHODS Patients had cataract surgery with implantation of one of the three above-mentioned IOLs. Higher order aberrations (HOAs), modulation transfer function (MTF), point spread function (PSF), retinal straylight, and dysphotopsia phenomena were evaluated 3 months after surgery. IOL decentration was quantified as the distance between the visual axis center and the IOL center using the OPD-Scan III aberrometer (Nidek Co., Ltd., Gamagori, Japan). The patients who received each IOL type were then divided into two subgroups (decentration of ⩽ 0.25 or > 0.25 mm) to analyze the effect of IOL decentration on these optical qualities. RESULTS The study included 54 eyes (54 patients), with 18 eyes in each IOL group. The distance of IOL decentration did not differ significantly among the three groups. With a decentration of more than 0.25 mm, MTF, PSF, and coma were only significantly deteriorated in the bifocal IOL (ZMB00; Abbott Medical Optics, Santa Ana, CA). HOAs, coma, PSF, and glare perception were better in the monofocal and EDOF IOLs than those in the ZMB00 IOL when decentration was more than 0.25 mm. Furthermore, IOL decentration was significantly correlated with HOAs, coma, MTF, and PSF in the ZMB00 IOL. CONCLUSIONS The monofocal and EDOF IOLs are more immune to optical quality degradation caused by IOL decentration than the ZMB00 IOL. [J Refract Surg. 2019;35(8):484-492.].

偏心度对单焦点,扩展焦深和双焦点人工晶状体的光学质量的影响。

目的比较三种人工晶状体植入患者的人工晶状体(IOL)偏心度对光学质量的影响:单焦点,扩展景深(EDOF)和双焦点。方法患者接受了上述三种IOL之一的白内障手术。术后3个月评估高阶像差(HOA),调制传递函数(MTF),点扩散函数(PSF),视网膜杂散光和视光异常现象。使用OPD-Scan III像差计(日本,Gmagori,Nidek Co.,Ltd。),将IOL偏心量化为视轴中心与IOL中心之间的距离。然后将接受每种IOL类型的患者分为两个亚组(de 0.25或> 0.25 mm的偏心),以分析IOL偏心对这些光学质量的影响。结果该研究包括54眼(54例患者),每个IOL组中有18眼。在三组中,IOL分散的距离没有显着差异。偏心距大于0.25 mm时,MTF,PSF和昏迷仅在双焦点IOL(ZMB00; Abbott Medical Optics,加利福尼亚州圣安娜)中显着恶化。当偏心度大于0.25 mm时,单焦点和EDOF IOL中的HOA,昏迷,PSF和眩光感要优于ZMB00 IOL。此外,在ZMB00 IOL中,IOL浓度与HOA,昏迷,MTF和PSF显着相关。结论单焦点和EDOF IOL比ZMB00 IOL更不受IOL偏心引起的光学质量下降的影响。[J Refract Surg。2019; 35(8):484-492。]。在三组中,IOL分散的距离没有显着差异。偏心距大于0.25 mm时,MTF,PSF和昏迷仅在双焦点IOL(ZMB00; Abbott Medical Optics,加利福尼亚州圣安娜)中显着恶化。当偏心度大于0.25 mm时,单焦点和EDOF IOL中的HOA,昏迷,PSF和眩光感要优于ZMB00 IOL。此外,在ZMB00 IOL中,IOL浓度与HOA,昏迷,MTF和PSF显着相关。结论单焦点和EDOF IOL比ZMB00 IOL更不受IOL偏心引起的光学质量下降的影响。[J Refract Surg。2019; 35(8):484-492。]。在三组中,IOL分散的距离没有显着差异。偏心距大于0.25 mm时,MTF,PSF和昏迷仅在双焦点IOL(ZMB00; Abbott Medical Optics,加利福尼亚州圣安娜)中显着恶化。当偏心度大于0.25 mm时,单焦点和EDOF IOL中的HOA,昏迷,PSF和眩光感要优于ZMB00 IOL。此外,在ZMB00 IOL中,IOL浓度与HOA,昏迷,MTF和PSF显着相关。结论单焦点和EDOF IOL比ZMB00 IOL更不受IOL偏心引起的光学质量下降的影响。[J Refract Surg。2019; 35(8):484-492。]。雅培医学光学公司,加利福尼亚州圣安娜)。当偏心度大于0.25 mm时,单焦点和EDOF IOL中的HOA,昏迷,PSF和眩光感要优于ZMB00 IOL。此外,在ZMB00 IOL中,IOL浓度与HOA,昏迷,MTF和PSF显着相关。结论单焦点和EDOF IOL比ZMB00 IOL更不受IOL偏心引起的光学质量下降的影响。[J Refract Surg。2019; 35(8):484-492。]。雅培医学光学公司,加利福尼亚州圣安娜)。当偏心度大于0.25 mm时,单焦点和EDOF IOL中的HOA,昏迷,PSF和眩光感要优于ZMB00 IOL。此外,在ZMB00 IOL中,IOL浓度与HOA,昏迷,MTF和PSF显着相关。结论单焦点和EDOF IOL比ZMB00 IOL更不受IOL偏心引起的光学质量下降的影响。[J Refract Surg。2019; 35(8):484-492。]。结论单焦点和EDOF IOL比ZMB00 IOL更不受IOL偏心引起的光学质量下降的影响。[J Refract Surg。2019; 35(8):484-492。]。结论单焦点和EDOF IOL比ZMB00 IOL更不受IOL偏心引起的光学质量下降的影响。[J Refract Surg。2019; 35(8):484-492。]。
