衍射
折射、衍射混合使用
选择多焦晶体原因,实现的方法:
单焦晶体属于折射
专利的AVH ™襻
专利的AVH ™襻—优异的稳定性
专利的AVH襻技术〔抗屈折技术〕提供一个可控制的、渐进性的张力来对抗囊袋的收缩,使得Rayner晶体拥有极佳的稳定性
居中性
旋转稳定性
对抗倾斜和轴向位移
专利的AVH ™襻—优异的稳定性
无论在任何直径的囊袋内,AVH襻通过外襻和内襻的共同作用,
以获得最好的囊袋稳定性。

The aim of our study was to compare functional results of cataract surgery in patients implanted with M-FLEX (Rayner, UK) multifocal IOL’s with different additions for near vision
PURPOSE
Efficacy, safety, predictability and stability of the refractive results, intraoperative and postoperative complications and patients satisfaction with VF-14 test were evaluated
METHODS
Addition power for near
