Computer ray tracing provides a simple technique for investigating binocular relative spectacle magnification (BRSM) in the patient with unilateral aphakia. BRSM is defined as the retinal image size in the corrected aphakic eye relative to the retinal image size in the corrected phakic eye. The influence of preoperative ametropia and the mode of correction on BRSM is investigated, using Gullstrand's number 2 schematic eye as a model.
计算机光线追踪为研究单眼无晶状体患者的双眼相对眼镜放大率（BRSM）提供了一种简单的技术。BRSM定义为矫正后的无晶状体眼的视网膜图像大小相对于矫正后的有晶状体眼的视网膜图像大小。以Gullstrand 2号简化眼为模型，研究术前屈光不正和矫正方式对BRSM的影响。
