To test the longterm findings for glare and contrast sensitivity in patients with diffractive multifocal intraocular lenses.
Measurements were done using the Mesoptometer II under standardized contrast level and brightness illumination settings (0.032 and 0.1 cd/m2 brightness illumination for testing contrast sensitivity (0.1 cd/m2 brightness illumination and glare of 0.35 Lux for glare testing). Furthermore the patients were tested on their ability to fulfill the requirements of the German Ophthalmological Society (DOG) for mesopic vision to obtain a driver's license.
40 patients with multifocal intraocular lenses (MIOL), aged 59.3 +/- 9.1 years, were examined 2 years after lens implantation (3M 815 LE and 3M 825 XE) and compared to results of a control-group of 40 patients with monofocal IOL's.
There were no significant differences testing contrast sensitivity. Patients with monofocals, however, reached significant better results than patients with multifocals (p < 0.01) when tested for visual acuity under low contrast conditions and glare sensitivity.
Seventy percent of MIOL-patients and 56% of Monofocal-patients failed to meet the minimum requirements for driver's license. Both patient groups showed decreased values for glare and contrast sensitivity when tested 2 years after cataract surgery.
测试使用衍射多焦点人工晶状体患者的眩光和对比敏感度的长期研究结果。
在标准化的对比度水平和亮度照明设置下（测试对比敏感度时亮度照明为0.032和0.1cd/m²，测试眩光时亮度照明为0.1cd/m²且眩光为0.35勒克斯），使用Mesoptometer II进行测量。此外，对患者满足德国眼科学会（DOG）中关于获得驾驶执照所需的中间视觉要求的能力进行测试。
40例植入多焦点人工晶状体（MIOL）的患者，年龄59.3±9.1岁，在晶状体植入2年后（3M 815 LE和3M 825 XE）接受检查，并与40例植入单焦点人工晶状体的对照组患者的结果进行比较。
在测试对比敏感度方面没有显著差异。然而，在低对比度条件下测试视力和眩光敏感度时，单焦点人工晶状体患者的结果明显优于多焦点人工晶状体患者（p<0.01）。
70%的多焦点人工晶状体患者和56%的单焦点人工晶状体患者未达到获得驾驶执照的最低要求。两组患者在白内障手术后2年进行测试时，眩光和对比敏感度值均降低。
