To compare a handheld and a digital pupillometer in determining pupil size in a population of refractive surgery candidates (group 1) and after implantation of an Artisan phakic intraocular lens (PIOL) for correction of myopia (group 2).
Pupil size was measured with the Colvard and Procyon pupillometers in 121 eyes in group 1 and 83 eyes in group 2. Pupil sizes measured with the Colvard device were compared with the scotopic, mesopic-low and mesopic-high measurements taken with the Procyon pupillometer in both groups. Analysis of comparison between pupil measurements was performed according to methods described by Bland and Altman.
The mean Colvard scotopic pupil diameter, scotopic, mesopic-low and mesopic-high Procyon pupil diameters were 5.86 +/- 0.81 mm, 6.42 +/- 0.88 mm, 5.55 +/- 0.95 mm and 4.21 +/- 0.73 mm in group 1 and 5.32 +/- 0.67 mm, 6.14 +/- 0.81 mm, 5.33 +/- 0.78 mm and 4.02 +/- 0.55 mm in group 2, respectively. The Colvard diameter compared most favourably with the Procyon mesopic-low diameter (group 2; p = 0.78).
Measurements of pupil diameter with the Colvard pupillometer correlated best with measurements taken by the Procyon pupillometer under standardized mesopic-low light conditions. We believe that digital binocular infrared pupillometry is advantageous for obtaining standardized measurements of pupil size.
比较手持瞳孔计和数字瞳孔计在屈光手术候选人群（第1组）以及植入Artisan有晶状体眼人工晶状体（PIOL）矫正近视后（第2组）测量瞳孔大小的情况。
使用Colvard瞳孔计和Procyon瞳孔计分别测量第1组121只眼和第2组83只眼的瞳孔大小。将Colvard设备测量的瞳孔大小与两组中Procyon瞳孔计在暗视、中间视低光和中间视高光条件下测量的结果进行比较。根据Bland和Altman描述的方法对瞳孔测量结果进行比较分析。
第1组中，Colvard暗视瞳孔平均直径、Procyon暗视、中间视低光和中间视高光瞳孔直径分别为5.86±0.81mm、6.42±0.88mm、5.55±0.95mm和4.21±0.73mm；第2组分别为5.32±0.67mm、6.14±0.81mm、5.33±0.78mm和4.02±0.55mm。Colvard测量的直径与Procyon中间视低光直径最为匹配（第2组；p = 0.78）。
在标准化的中间视低光条件下，Colvard瞳孔计测量的瞳孔直径与Procyon瞳孔计测量的结果相关性最佳。我们认为数字双目红外瞳孔测量法有利于获得标准化的瞳孔大小测量结果。
