Abstract

Slowing the progression of myopia has become an extensive concern for parents of children with myopia. According to research findings in animals, eye growth is primarily influenced by the peripheral retina. Treatment options such as orthokeratology, daytime bifocal or multifocal soft contact lens usage are available because they can induce relative myopia in the periphery. In this work, a new multifocal rigid gas permeable (MFRGP) contact lens for myopia prevention and control in adolescents was designed specifically for preventing and controlling myopia in adolescents. This lens features a multi-tangent alignment curve, smaller spherical aberration, and transition defocus. FocalPoints and UPC 100 Vision were used for lens design and lathing, respectively. The lens structure and power profile were measured using IS830 and CONTEST 2, respectively. The elimination of lens aberrations was achieved through design optimization using ZEMAX with ray tracing. Lens fitting was evaluated using slit-lamp microscopy and corneal topography.

用于控制近视的多角度定位和球面像差校正多焦点硬性透气隐形眼镜

减缓近视的发展已成为近视儿童家长广泛关注的问题。根据对动物的研究发现，眼睛的发育主要受周边视网膜的影响。正视角膜塑形镜、日间双焦点或多焦点软性隐形眼镜等治疗方法都能诱导周边视网膜的相对近视。在这项研究中，我们设计了一种用于预防和控制青少年近视的新型多焦点硬性透气（MFRGP）隐形眼镜。该镜片具有多切线排列曲线、较小的球面像差和过渡散焦功能。FocalPoints 和 UPC 100 Vision 分别用于镜片的设计和车工。镜片结构和功率曲线分别使用 IS830 和 CONTEST 2 进行测量。通过使用 ZEMAX 和光线跟踪进行设计优化，消除了镜片像差。使用裂隙灯显微镜和角膜地形图对镜片的装配进行了评估。
