周邊屈光眼鏡模型之設計

The Model Design of A Peripheral Refraction Spectacle Lens

指導教授 : 黃宣瑜

摘要


近視是一項全球性的公共衛生議題,在台灣地區近視率的盛行率達80%以上,在世界各國,近視和高度近視的盛行率以驚人的速度不斷增加,與高度近視相關的疾病包含黃斑部病變、白內障和青光眼等等,隨著近視的增加,視力障礙的風險也隨之提升。 目前近視的方法有:藥物治療(如阿托品)、眼鏡、隱形眼鏡、角膜塑型片等等。動物研究指出,屈光的狀態對視覺的發育有重大的的影響,周邊視網膜的成像位置對於近視的發展有重大的影響,整體而言,考量周邊屈光的近視控制策略,會是更有效的方式。 本篇研究目的為建立一個可以改變眼球周邊屈光狀態的鏡片模W型,利用ASAP光學模擬分析軟體來建立模型,並且分析視網膜影像及光通量,研究結果以-2.50D、-5.00D及-7.50D三種度數作為範例,結果指出,本研究成功建立可以改變周邊屈光狀態的鏡片模型,未來可望應用於人眼的近視控制上。

Myopia has now become a global public health issue. In Taiwan, the prevalence of myopia in children has been up to more than 80%. In many other countries, the prevalence of myopia and high myopia is rising at an alarming rate as well, with significant increases in the risks for vision impairment from pathological conditions associated with high myopia, including macular degeneration, cataract and glaucoma. With the increase in myopia, the risk of visual disability also increased To date, the following have been used for myopia control: medication, (such as Atropine eye drops), spectacles, contact lens and orthokeratology. Research involving many animal species has demonstrated that refractive condition plays a role in vision development, while the imaging position of peripheral retina has tremendous influence on myopia progression. Thus, a myopia control strategy taking into account the peripheral refraction is likely to be more effective. The purpose of this study is, using ASAP optical software, to create a spectacle lens model which is able to change peripheral refractive condition, and to analyze the image and the luminous flux in the retina. The potentials of the procedure is presented as the three design examples of -2.50D, -5.00D and -7.50D. The results show that this spectacle lens model is able to change peripheral refractive errors and, in the future, may be used to reduce progression of myopia.
