“这种多灶性IOL的非球面设计增强了患者的结果”，伊丽莎白A. Davis说，MD。“有许多不同的IOL可供选择，以实现今天患者的最佳结果。翘曲校正镜头现在可用，结果良好。在许多情况下，外科医生根据他们的设计和积极成果，更喜欢TECNIS多焦体IOL（Abbott Medical Optics Inc. [Amo]）。“

在评估任何IOL时，您必须考虑几个因素：易于植入，屈光结果的可预测性，视觉质量，焦点范围（眼镜独立），患者的满意度，副作用和长期稳定性。

TECNIS多灶性IOL基于非球面光学设计，意指将平均角膜的球面像差降低到零。TECNIS多灶具有全衍射后表面，其使得衍射光学瞳孔独立于在任何照明条件下的所有距离处的最佳图像质量。光学器件由丙烯酸制成，并采用单件和三件套设计。磨砂边缘也最大限度地减少了边缘眩光。

多焦点人工晶体固有的低对比度、induce some amount of glare and halos, it is important to inform all patients that they should anticipate such side effects. Achieving optimal refractive outcomes with the Tecnis Multifocal IOL requires careful preoperative, intraoperative, and postoperative care. Preoperative preparation requires optimization of the ocular surface, a thorough examination to exclude patients with conditions that would preclude good outcomes, and precise biometry and IOL calculations.

To achieve the best results with the lens, it is important to choose appropriate candidates. Certainly, patients should desire reduced dependence on glasses and contact lenses. They should understand not only the risks of cataract surgery in general but the potential side effects of the lens, including reduced contrast, glare, and halos. Either patients should have minimal corneal astigmatism, or the surgeon should have an appropriate method to manage astigmatism. Accurate preoperative keratometric and biometric measurements are critical, and ocular surface disease must be aggressively treated.

老花眼矫正IOL是前段眼科实践中最重要的转化因素之一，伊克里斯·伊克斯恢复（Alcon Laboratories，Inc。）衍射多焦透镜是美国最常用的老花眼校正IOL。该技术为患者提供功能距离，阅读和中间视觉的患者视觉康复。外科医生的选择患者，细致的细节关注，术后结果的优化是与该镜头成功成功的钥匙。

Recent advances in technology with laser cataract surgery may permit greater centration and consistent sizing of the capsulorhexis that could enhance refractive outcomes with presbyopia-correcting IOLs. Accurate biometry with the IOLMaster (Carl Zeiss Meditec, Inc.) or the Lenstar LS 900 (Haag-Streit AG) and control of astigmatism are also essential to maximizing outcomes. Because the lens constant must be carefully personalized to the individual surgeon, tracking postoperative results is imperative to refine surgical outcomes.

患者对较老年矫正IOL的小屈光误差令人难以置信，因此外科医生必须愿意和能够对待它们。在症状患者中大于0.50d的散光需要手术计划。

引起残留屈光误差，眼表面，2个囊状黄斑水肿和后囊，外科医生可以通过伊克里斯恢复IOL提高适当的患者的视觉质量。通过减少或消除他们对眼镜的需求，该技术提高了许多伪患者的生活质量。由于Mevericians对多焦点镜片的舒适度，未来几年来，这些IOL应该变得更加流行，无论是白内障和屈光外科医生及其患者。
