Abstract: | 隨著人類平均壽命的增長,越來越多人受到眼睛退化的困擾,水晶體的退化使得需要更換人工水晶體的患者增加,國際組織也開始關注此議題,為了更精準的提供患者所需的人工水晶體,有許多研究關於人眼數據的量測、人工水晶體的設計和植入人眼後的成像品質。從最初使患者能看到遠距離勢力範圍的單焦人工水晶體到現在視力範圍擴大到多焦的人工水晶體,而設計方面則是從折射光學結構到折射和繞射混和式的結構,因此本研究設計朝折射和繞射混和式的三焦人工水晶體並分析其成像品質,並和其他市售多焦的人工水晶體比較,在增加焦距範圍且維持成像品質為設計多焦人工水晶體的挑戰。
此外,利用紫外光-可見光-近紅外光光譜儀、Shack-Hartmann波前量測系統和多功能顯微拉曼分析儀對此研究水凝膠材料的性質有更進一步的了解,提供未來人工水晶體設計的參考。 With the increasing average lifespan of humans, more and more people are experiencing age-related eye degeneration. The degeneration of the intraocualr lens leads to an increasing number of patients requiring intraocualr intraocular lens. International organizations have also begun to pay attention to this issue. In order to provide more accurate intraocualr intraocular lens to patients, there are many studies focused on measuring human eye data, designing intraocualr lenses, and evaluating the imaging quality after implantation. From the first monofocal intraocular lens that allowed patients to see in the distance, to the current multifocal intraocular lens that expand the range of vision. The design has evolved from refractive optical structures to a combination of refraction and diffraction. Therefore, this study aims to design a trifocal intraocular lens with a combination of refraction and diffraction and analyze its imaging quality. A comparison is made with other commercially available multifocal lenses. The challenge of increasing the focal range while maintaining imaging quality in designing multifocal intraocular intraocular lens. In addition, the use of ultraviolet-visible-near-infrared spectroscopy , Shack-Hartmann wavefront measurement system and multifunctional micro-Raman analysis provides material properties of the hydrogel material in this study, offering references for future intraocular lens design. |
