Abstract
Since the Scheimpflug principle was first described over a century ago, there has been a great interest among ophthalmologists for the use of Scheimpflug camera in anterior segment imaging. Scheimpflug imaging has since advanced significantly and modern day instruments provide comprehensive imaging and topographic data of the anterior segment. In this article the clinical applications and limitations of Scheimpflug imaging in modern cataract surgery patients are discussed. This article reviews recent work on assessment of lens transparency for cataract grading and integrity, using preoperative lens density measurements to help predict phacoemulsification parameters, its utility in challenging situations like capsular bag distension syndrome and traumatic cataract and assessment of density of the posterior capsule for objectively quantifying posterior-capsule opacification.
摘要
自一个多世纪前首次描述了Scheimpflug原理以来，眼科医生对使用Scheimpflug相机进行眼前段成像一直有着浓厚的兴趣。从那时起，Scheimpflug成像技术有了显著进展，现代仪器可提供眼前段的全面成像和地形图数据。本文讨论了Scheimpflug成像在现代白内障手术患者中的临床应用及局限性。本文回顾了近期关于利用术前晶状体密度测量评估晶状体透明度以进行白内障分级和完整性评估、帮助预测超声乳化参数、在诸如囊袋扩张综合征和外伤性白内障等具有挑战性的情况下的效用，以及客观量化后囊混浊的后囊密度评估等方面的研究工作。
