About 35% of intraocular lenses now implanted in the United States are narrow profile lenses, measuring on the average 5.0 mm by 6.0 mm. This study sought to determine whether these lenses cause unwanted optical images with a decrease in the quality of vision. Seventy-five eyes with a 5.0 mm x 6.0 mm intraocular lens (IOL) were compared with 75 eyes with a 6.5 mm IOL. All patients had capsulorhexis, phacoemulsification, and capsular fixation of the IOL. There was no statistically significant difference in unwanted visual images (16% and 20%, respectively), ability to drive at night (79% and 69%), or patient satisfaction. Careful patient selection is, however, important.
目前在美国植入的人工晶状体中，约35%是窄型晶状体，平均尺寸为5.0毫米×6.0毫米。本研究旨在确定这些晶状体是否会因视力质量下降而产生不必要的光学图像。将75只植入5.0毫米×6.0毫米人工晶状体（IOL）的眼睛与75只植入6.5毫米IOL的眼睛进行比较。所有患者均接受了撕囊、超声乳化和IOL囊袋固定术。在不必要的视觉图像（分别为16%和20%）、夜间驾驶能力（79%和69%）或患者满意度方面，没有统计学上的显著差异。然而，仔细选择患者很重要。
