To compare monocular visual performance of a spherical and an enhanced monofocal intraocular lens (IOL) after combined implantation.
This prospective study comprised 50 patients (100 eyes) with bilateral cataract surgery and implantation of the spherical Sensar AAB00 IOL (Johnson & Johnson Vision) in the dominant eye and the enhanced monofocal Eyhance ICB00 IOL (Johnson & Johnson Vision) in the non-dominant eye. Postoperative assessment compared monocular CDVA, CNVA, DCIVA, DCNVA, low contrast visual acuities, defocus curves, wavefront aberrometry, decentration, tilt, and the 7-item Visual Function Index (VF-7) questionnaire.
Monocular DCIVA at 66 cm (spherical: 0.33 ± 0.13 vs enhanced monofocal: 0.37 ± 0.13 logarithm of the minimum angle of resolution (logMAR), = .007), DCIVA at 80 cm (spherical: 0.24 ± 0.12 vs enhanced monofocal: 0.31 ± 0.11 logMAR, < .001), and DCNVA at 40 cm (spherical: 0.49 ± 0.17 vs enhanced monofocal: 0.56 ± 0.13, = .003) increased significantly with the enhanced monofocal IOL. Similarly, monocular low contrast intermediate ( = .048) and corrected ( = .006) near vision were better in the enhanced monofocal group. Defocus curves from -0.25 to -1.50 D ( < .05) and internal spherical aberrations Z(4,0) ( < .001) differed between the two IOLs. CDVA, decentration, and tilt were comparable ( > .05).
This fellow-eye study demonstrated significant differences between the enhanced monofocal IOL and the spherical IOL. Visual improvements with the enhanced monofocal IOL were modest for both intermediate and near vision. There was no significant difference in distance vision, decentration, or tilt, and higher order aberrations were low. .
比较联合植入后球面人工晶状体（IOL）和增强型单焦点人工晶状体的单眼视觉性能。
这项前瞻性研究纳入了50例（100只眼）接受双眼白内障手术的患者，在主眼植入球面Sensar AAB00人工晶状体（强生视力），在非主眼植入增强型单焦点Eyhance ICB00人工晶状体（强生视力）。术后评估比较了单眼最佳矫正视力（CDVA）、矫正近视力（CNVA）、未矫正远视力（DCIVA）、未矫正近视力（DCNVA）、低对比度视力、散焦曲线、波前像差、偏心、倾斜以及7项视觉功能指数（VF - 7）问卷。
增强型单焦点人工晶状体组在66 cm处的单眼未矫正远视力（球面：0.33±0.13对比增强型单焦点：0.37±0.13最小分辨角对数（logMAR），P = 0.007）、80 cm处的未矫正远视力（球面：0.24±0.12对比增强型单焦点：0.31±0.11 logMAR，P < 0.001）以及40 cm处的未矫正近视力（球面：0.49±0.17对比增强型单焦点：0.56±0.13，P = 0.003）均有显著提高。同样，增强型单焦点组的单眼低对比度中间视力（P = 0.048）和矫正近视力（P = 0.006）更好。两种人工晶状体在 - 0.25至 - 1.50 D的散焦曲线（P < 0.05）和内部球差Z(4,0)（P < 0.001）方面存在差异。最佳矫正视力、偏心和倾斜情况相当（P > 0.05）。
这项对侧眼研究表明增强型单焦点人工晶状体和球面人工晶状体之间存在显著差异。增强型单焦点人工晶状体在中间视力和近视力方面的视觉改善较为适度。远视力、偏心或倾斜方面无显著差异，高阶像差较低。
