论文摘要
角膜嵌体（CIS）是最新的外科手术程序，用于治疗长期治疗的患者，这些患者希望完全独立于使用眼镜或隐形眼镜。尽管长期患者的屈光手术主要与白内障手术结合进行，但是当无需植入眼内镜头时，CIS的选择具有最小的侵入性。 CIS的当前设计要么是：小孔设备或折射设备，但是，两种方法在无法适应的眼睛中的中间和接近距离时都没有良好的性能。在本研究中，我们提出了三焦点CI的第一个设计，同时允许在老年眼睛中，迄今为止，中间和近乎视力。我们首先通过使用光学设计软件与市售CI相比，首先证明了新镶嵌物的良好性能。接下来，我们通过基于自适应的光学模拟器，实验确认提案的图像形成能力。这种新设计还具有许多参数，可以变化以制作个性化的三焦点CI，为治疗长老会的新途径开辟了新的途径。
Corneal inlays (CIs) are the most recent surgical procedure for the treatment of presbyopia in patients who want complete independence from the use of glasses or contact lenses. Although refractive surgery in presbyopic patients is mostly performed in combination with cataract surgery, when the implantation of an intraocular lens is not necessary, the option of CIs has the advantage of being minimally invasive. Current designs of CIs are, either: small aperture devices, or refractive devices, however, both methods do not have good performance simultaneously at intermediate and near distances in eyes that are unable to accommodate. In the present study, we propose the first design of a trifocal CI, allowing good vision, at the same time, at far, intermediate and near vision in presbyopic eyes. We first demonstrate the good performance of the new inlay in comparison with a commercially available CI by using optical design software. We next confirm experimentally the image forming capabilities of our proposal employing an adaptive optics based optical simulator. This new design also has a number of parameters that can be varied to make personalized trifocal CI, opening up a new avenue for the treatment of presbyopia.
