伊丽莎白·A·戴维斯(Elizabeth A. Davis)说:“这种多焦点IOL的非球面设计增强了患者的结果。”“有许多不同的IOL可供选择,以便为当今患者取得最佳结果。早期校正镜片现在可用,并具有良好的效果。在许多情况下,外科医生更喜欢基于其设计和积极结果的Tecnis多焦点IOL(Abbott Medical Optics Inc. [AMO])。”
In assessing any IOL, you must consider several factors: ease of implantation, predictability of refractive outcome, quality of vision, range of focus (spectacle independence), patients’ satisfaction, side effects, and long-term stability.
The Tecnis Multifocal IOL is based on an aspheric optic design meant to reduce the spherical aberration of an average cornea to zero. The Tecnis Multifocal has a full-diffractive posterior surface, which makes the diffractive optics pupil independent for optimal image quality at all distances under any lighting condition. The optic is made of acrylic and comes in both a one- and three-piece design. The frosted edge also minimizes edge glare.

All multifocal IOLs inherently reduce contrast and 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.
长期校正的IOL是前节眼科实践中最重要的转换因素之一,而iQ Restor(Alcon Laboratories,Inc。)衍射多焦点透镜是美国在美国最常见的植入的Persybyopia Pressbyopia prockypopia镜头。该技术为患者提供视觉康复,以进行功能距离,阅读和中间视力。外科医生选择患者,对细节的细致关注以及术后结果的优化是该镜头成功结局的关键。
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.
患者对小花疗法的IOL对小折射错误非常敏感,因此外科医生必须愿意并且能够治疗它们。在有症状的患者中,大于0.50 d的散光需要手术计划。
由于注意残留折射误差,眼表面,2个囊状黄斑水肿和后囊,外科医生可以通过IQ Restor IOL的丙烯酸肌ry剂提高适当的患者视力质量。该技术通过减少或消除对眼镜的需求,提高了许多假性晶状体患者的生活质量。随着医生对多焦点镜头的舒适感在未来几年有所改善,这些IOL应该在白内障和屈光外科医生及其患者中变得越来越受欢迎。
