To compare internal optical aberrations between three different intraocular lenses (IOL) of the same Tecnis platform: monofocal ZCB00, multifocal ZMB00, and enlarged depth-of-focus (EDoF) Symfony ZXR00.
We included in this study 236 eyes of 118 patients who had been bilaterally implanted either with the monofocal, the multifocal, or the EDoF IOL. They were examined with the K1-RW wavefront analyzer (Topcon Medical Systems) 2 months after surgery. Patients with any ocular pathology were excluded from the study. Only high-order aberrations (HOA) of the third and fourth orders of the Zernike polynomials were considered.
Forty-three patients (86 eyes) were implanted with the monofocal IOL, 45 patients (90 eyes) with the ZMB00 IOL, and 30 patients (60 eyes) with the EDoF Symfony IOL. Mean age was 62.42 ± 7.38, 63.60 ± 6.01, and 64.74 ± 5.84 years, respectively. Mean axial length was 23.37 ± 1.00, 23.49 ± 1.00, and 23.54 ± 0.73 mm, respectively. For a 6-mm pupil, internal total HOA in the monofocal group was 1.01 ± 1.75 μm; in the bifocal group was 1.35 ± 2.12 μm; and in the Symfony group was 0.72 ± 0.63 μm. No optical aberration differences were found among the three groups ( > 0.05).
There are no differences regarding internal optical aberrations between these three IOLs when analyzing them with optical aberrometry. Patients' pupil size should be considered for the selection of the most appropriate IOL to be implanted, because despite a same optical platform, every IOL implies a different increase of HOA with larger pupil sizes.
比较同一Tecnis平台的三种不同人工晶状体（IOL）的眼内光学像差：单焦点ZCB00、多焦点ZMB00和扩大景深（EDoF）Symfony ZXR00。
本研究纳入了118例患者的236只眼，这些患者均接受了双侧单焦点、多焦点或EDoF人工晶状体植入术。术后2个月，使用K1-RW波前分析仪（拓普康医疗系统公司）对他们进行检查。患有任何眼部疾病的患者被排除在研究之外。仅考虑泽尼克多项式的三阶和四阶高阶像差（HOA）。
43例患者（86只眼）植入了单焦点人工晶状体，45例患者（90只眼）植入了ZMB00人工晶状体，30例患者（60只眼）植入了EDoF Symfony人工晶状体。平均年龄分别为62.42±7.38岁、63.60±6.01岁和64.74±5.84岁。平均眼轴长度分别为23.37±1.00mm、23.49±1.00mm和23.54±0.73mm。对于6mm的瞳孔，单焦点组的眼内总高阶像差为1.01±1.75μm；双焦点组为1.35±2.12μm；Symfony组为0.72±0.63μm。三组之间未发现光学像差差异（P>0.05）。
使用光学像差仪分析时，这三种人工晶状体的眼内光学像差无差异。选择最合适植入的人工晶状体时应考虑患者的瞳孔大小，因为尽管光学平台相同，但随着瞳孔增大，每种人工晶状体引起的高阶像差增加不同。
