人工晶状体眼伪调节研究进展

Advanced research on pseudophakic accommodation of eyes with artificial lens

许多白内障术后患者可以获得比实际预期要好的近视力,其中原因在于人工晶状体眼伪调节的存在。人工晶状体眼伪调节的测量方法主要包括:推进法、离焦法、动态检影法、红外线可视验光仪、视觉诱发电位法及利用A型超声或超声生物显微镜测量调节前后前房深度的变化间接测定调节幅度。人工晶状体眼伪调节的影响因素主要包括景深、人工晶状体位移、近视散光、像差、角膜的多焦性等。

With the increase of population and the coming of aging ,. more and more patients suffer from cataract and need to be treated by surgical operation. Meanwhile, as the development of society, for a better life, patients are being desirous not only to see clearly, but also to see comfortably. So, they paid more attention on artificial lens accommodation function after cataract operation. It was found that visual acuity of young patients was better than that of elders after cataract operation and many researchers had made much investigation before. We made a review on the research history, measurement methods and influence factors of artificial lens accommodation.
