Kappa角在眼科手术中的临床应用及研究进展

Clinical application and research progress of angle Kappa in ophthalmic surgery

摘要:

人眼具有多种轴线和角度，其中Kappa角是反映人眼居中性的重要指标，在眼科手术中应用广泛。术前正确的评估与应用Kappa角，有利于恢复术后最佳视觉质量。μ弦是近几年为了更好地表达Kappa角而出现的一个新术语。临床上这两个概念未被很好地理解，限制了其实用性。因此，为了更好地理解Kappa角和μ弦，本文分别阐述了两者的定义和联系。同时，总结了Kappa角在斜视手术中的应用，探讨了在角膜屈光手术中补偿大Kappa角的方法以及在超声乳化联合多焦点人工晶状体(MIOL)植入术中参考Kappa角预测术后MIOL居中性的临床意义，以期为临床工作提供一定的参考。

Abstract:

The human eye has various axes and angles, of which the angle Kappa is an important indicator of the centrality of the human eye and is widely used in ophthalmic surgery. Proper preoperative evaluation and application of the angle Kappa facilitated the achievement of optimal postoperative visual quality. Chord mu is a new term that has emerged recently to better express the angle Kappa. The two concepts are not well understood clinically, limiting their usefulness. Therefore, to better understand the angle Kappa and chord mu, the definitions and connections between them are presented separately in this paper. Meanwhile, the application of angle Kappa in strabismus surgery was summarized, the method for compensating large angle Kappa in corneal refractive surgery and the clinical significance of angle Kappa in predicting postoperative centrality of multifocal intraocular lens(MIOL)in phacoemulsification combined with MIOL implantation were discussed, with a view to providing references for clinical work.
