Modified monovision-or "mini-monovision"-is an alternative method to multifocal intraocular lenses (IOLs) for treating presbyopia. This study aimed to evaluate the clinical outcomes of patients bilaterally implanted with the new enhanced monofocal Tecnis Eyhance (ICB00) IOLs with the mini-monovision technique to improve near vision. In this retrospective case series, the medical records of 50 patients (100 eyes) who underwent bilateral cataract surgery were reviewed. Patients were divided into the Emmetropia and Mini-monovision groups based on the postoperative spherical equivalent and residual myopia. The binocular visual acuity for far (4 m), intermediate (66 cm), and near (40 cm) distances, binocular defocus curves, contrast sensitivity, visual symptoms, spectacle independence, and patient satisfaction rates were evaluated at 3 months postoperatively. The binocular uncorrected distance and intermediate visual acuities, contrast sensitivity, incidence of photic phenomena, and patient satisfaction were not significantly different between the two groups (p > 0.05). However, the binocular uncorrected near visual acuities and spectacle independence rates were significantly better in the Mini-monovision group (p < 0.001). Conclusively, the pseudophakic mini-monovision technique using enhanced monofocal IOLs may be a promising option for presbyopia correction in patients unsuitable for multifocal IOLs.
改良单视（“迷你单视”）是一种替代多焦点人工晶状体（IOL）治疗老视的方法。本研究旨在评估双侧植入新型增强型单焦点 Tecnis Eyhance（ICB00）IOL 并采用迷你单视技术改善近视力的患者的临床结果。在这项回顾性病例系列研究中，回顾了 50 名（100 只眼）接受双侧白内障手术患者的病历。根据术后球镜等效和残余近视，患者被分为正视眼和迷你单视组。术后 3 个月评估双眼远（4m）、中（66cm）和近（40cm）视力、双眼散焦曲线、对比敏感度、视觉症状、不戴眼镜的独立性和患者满意度。两组之间的双眼未矫正远视力和中距离视力、对比敏感度、视觉现象发生率和患者满意度无显著差异（p>0.05）。然而，迷你单视组的双眼未矫正近视力和不戴眼镜的独立性率显著更好（p<0.001）。总之，使用增强型单焦点 IOL 的假性近视迷你单视技术可能是不适合多焦点 IOL 的患者矫正老视的一种有前途的选择。
