摘要
在白内障患者日益增长的视觉期望和人工晶状体设计进步的推动下,白内障手术现在已经发展成为一种屈光手术,眼的高阶像差是影响视觉质量的重要因素,球差、彗差、三叶草差等高阶像差反映不同的光学特性,可从多方面影响视觉质量,进行屈光性白内障手术需尽可能减少高阶像差。非球面人工晶状体通过补偿球差、降低总高阶像差较球面人工晶状体改善了视觉质量。多焦点与单焦点人工晶状体的选择需结合患者使用需求及术前评估,多焦点人工晶状体植入术后并发症的解决手段也在探究中;回顾人眼高阶像差的作用机制,就人眼高阶像差与视觉质量的关系及影响、不同类型人工晶状体对高阶像差的影响进行综述,以期为白内障患者个性化选择人工晶状体提供新的参考,改善患者术后视觉质量。
With the development of cataract surgery technology and continuous improvement in people’s requirements for a better quality of life,traditional cataract surgery has been changed to refractive surgery. High-order aberrations,including spherical aberrations,comas,and trefoil aberrations,are important factors affecting visual quality—they represent different optical characteristics that could be affected by various aspects. The use of an aspheric intraocular lens improves visual quality by compensating for the spherical aberration and reducing total higher-order aberrations. To that end,the choice regarding the use of multifocal or monofocal intraocular lenses should consider the patients’ demands and the preoperative evaluation. Moreover,treatments for complications regarding multifocal intraocular lenses should also be explored. We reviewed the mechanisms of higher-order aberrations,the relationship between higher-order aberrations and visual quality,and the effects of different types of intraocular lenses on high-order aberrations. This paper aimed to provide a new reference for individualized intraocular lens selection in patients with cataract in order to provide better visual quality to the patients.
