Research progress of angle Kappa in refractive surgery / 眼科新进展

ABSTRACT

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.
