The dark-adapted threshold for a 2 degree white test imaged 10 degrees parafoveal and the foveal threshold luminance for Landolt ring gap discrimination were measured on 23 pseudophakic eyes with 6/9 or better visual acuity, 6 months to 3 years following posterior chamber lens implantation, and on 15 phakic eyes from an appropriately matched control group. Both scotopic and photopic thresholds were higher for the pseudophakic than for the control group by 0.3 and 0.6 log, respectively. These parafoveal and foveal thresholds, when measured under the influence of glare, were likewise significantly higher for the pseudophakic group.
对23只后房型人工晶状体植入后6个月至3年、视力为6/9或更好的假晶状体眼,以及来自适当匹配对照组的15只正视眼,测量了在中央凹旁10度处成像的2度白色测试的暗适应阈值和用于辨别兰多尔特环缺口的中央凹阈值亮度。假晶状体眼的暗视和明视阈值分别比对照组高0.3和0.6对数。在眩光影响下测量时,假晶状体组的这些中央凹旁和中央凹阈值同样显著更高。
