In a prospective study we implanted 34 monofocal posterior chamber lenses and 34 diffractive bifocal posterior chamber lenses. The corrected distance acuity of both groups with comparable age showed no significant difference. To compare functional results of both groups under mesopic conditions we examined all patients with the Mesoptometer II. We determined the visual acuity under field luminance of 1.0 cd/m2 and contrast thresholds under field luminance of 0.1 cd/m2. The results-of patients with diffractive bifocal posterior chamber lenses were significantly reduced compared with patients with monofocal posterior chamber lenses.
在一项前瞻性研究中，我们植入了34枚单焦点后房型人工晶状体和34枚衍射双焦点后房型人工晶状体。年龄相当的两组患者的矫正远视力无显著差异。为了比较两组在中间视觉条件下的功能结果，我们用Mesoptometer II对所有患者进行了检查。我们测定了1.0 cd/m²场亮度下的视力和0.1 cd/m²场亮度下的对比度阈值。与单焦点后房型人工晶状体患者相比，衍射双焦点后房型人工晶状体患者的结果显著降低。
