Kappa角在屈光手术中研究进展

Kappa角在眼科屈光手术中具有重要意义，Kappa角的补偿已成为共识，尤其在远视角膜屈光手术矫正中需慎重处理。Kappa角的人群分布特点受到种族、年龄、性别、眼别、眼屈光状态、眼球生物测量及不同精确度测量仪器的影响，Kappa角也可随着体位或瞳孔大小等因素的变化而变化。目前，合并大Kappa角飞秒激光及白内障超声乳化吸除联合多焦点人工晶状体置入术术后视觉质量分析及处理对策研究较少，需要更多大样本研究加入其中，进一步为临床医生提供依据。

Research progress of angle Kappa in refractive surgery

It is great significant for angle Kappa in refractive surgery，and it has been a consensus to adjust angle Kappa，especially in the correction of hyperopia corneal refractive surgery.The population distribution of angle Kappa is influenced by race，age，gender，eye，refractive status，ocular biometry and different precision measuring instruments，and it may also vary with the change of position or pupil size and other factors.At present，fewer researches on visual quality and treatment have been conducted in femtoseeond laser and cataract phacoemulsification combined with multifocal intraocular lens implantation in eyes with large angle Kappa，so more large sample researches are needed to perform in order to provide evidences for clinicians.
