高度近视并发白内障的视功能

随着高度近视患者的增多,高度近视并发的白内障日益受到重视。另外,以往临床上一直作为评价术后疗效主要指标的裸眼及最佳矫正视力,已很难涵盖视觉质量的全部内容。本文介绍调节集合功能、立体视功能、对比敏感度等现代视功能检查及其在高度近视并发白内障中的应用和临床意义,以及手术对视功能的影响。这些检查不仅对白内障的早期诊断、手术适应证把握、个体化IOL选择及植入术后视觉质量的评价有重要指导意义,而且有助于客观分析术后患者主观视觉质量差的原因并加以处理。熟悉视功能评价的内容和意义,有助于提高此类白内障的手术水平,使患者获得更好的术后视觉质量。

Visual function of cataract with high myopia

Cataract with high myopia is research priority associated with the large amount of high myopia patients. The unaided visual acuity and the best-corrected visual acuity are partial for the visual acuity of the patients with cataract. The mechanism and clinical significance of modern visual function measurements associated with cataract and high myopia, including accommodation and convergence, stereoscopic vision, contrast sensitivity, have been introduced. These measurements could be of great value in early diagnosis of cataract, assessment of surgical indication, customized intraocular lens(IOL)selection and evaluation of visual performance after IOL implantation. They could also be helpful to the analysis of postoperative impaired visual function and its management. Having an adequate understanding of the contents and significance of visual function was helpful to the improvement of cataract surgery techniques and postoperative visual acuity.
