To compare pre- and postoperative horizontal and vertical pupil diameters after horizontal Artisan phakic intraocular lens (PIOL) (Ophtec BV, Groningen, The Netherlands) implantation for correction of myopia.
The pre- and postoperative scotopic pupil diameters measured by the Colvard pupillometer (Oasis Medical, Glendora, Calif) were compared in 71 eyes after Artisan PIOL implantation (Artisan Colvard group). Analysis of pupil shape (vertical vs horizontal diameter, V/H ratio) after horizontal Artisan PIOL implantation was performed with the Procyon pupillometer (Procyon Instruments Ltd, London, United Kingdom) in 121 eyes (Artisan Procyon group) under scotopic, mesopic-low, and mesopic-high conditions and compared to an age- and refraction-matched control group of 121 eyes of refractive surgery candidates (Procyon control group).
After horizontal Artisan PIOL implantation, the mean horizontal pupil diameter decreased from 6.231 +/- 0.70 mm preoperatively to 5.34 +/- 0.68 mm postoperatively in the Artisan Colvard group (P < .01). The mean horizontal scotopic diameter was 5.60 +/- 0.66 mm, the mesopic-low diameter was 4.94 +/- 0.71 mm, and the mesopic-high diameter was 3.98 +/- 0.54 mm for the Artisan Procyon group. The mean horizontal scotopic diameter was 6.29 +/- 0.91 mm, the mesopic-low diameter was 5.40 +/- 0.96 mm, and the mesopic-high diameter was 4.16 +/- 0.80 mm in the Procyon control group. A significant increase was noted in V/H ratio under scotopic, mesopic-low, and mesopic-high conditions from 1.02, 1.02, and 1.01, respectively, in the Procyon control group to 1.17, 1.12, and 1.06, respectively, in the Artisan Procyon group (P < .01).
Horizontal pupil size was significantly decreased after horizontal Artisan PIOL implantation and might be attributed to a mechanical restriction of the iris in the horizontal meridian.
比较采用荷兰格罗宁根Ophtec BV公司的水平型Artisan有晶状体眼人工晶状体（PIOL）植入矫正近视前后的水平和垂直瞳孔直径。
比较71只接受Artisan PIOL植入眼（Artisan Colvard组）术前和术后采用Colvard瞳孔计（美国加利福尼亚州格伦多拉Oasis Medical公司）测量的暗视瞳孔直径。在暗视、低中视和高中视条件下，采用Procyon瞳孔计（英国伦敦Procyon Instruments Ltd公司）对121只接受水平型Artisan PIOL植入眼（Artisan Procyon组）的瞳孔形状（垂直与水平直径，V/H比值）进行分析，并与121名屈光手术候选者的年龄和屈光度匹配的对照组眼（Procyon对照组）进行比较。
在Artisan Colvard组中，水平型Artisan PIOL植入术后，平均水平瞳孔直径从术前的6.231±0.70mm降至术后的5.34±0.68mm（P<0.01）。Artisan Procyon组的平均暗视水平直径为5.60±0.66mm，低中视直径为4.94±0.71mm，高中视直径为3.98±0.54mm。Procyon对照组的平均暗视水平直径为6.29±0.91mm，低中视直径为5.40±0.96mm，高中视直径为4.16±0.80mm。在暗视、低中视和高中视条件下，Procyon对照组的V/H比值分别从1.02、1.02和1.01显著增加至Artisan Procyon组的1.17、1.12和1.06（P<0.01）。
水平型Artisan PIOL植入术后水平瞳孔大小显著减小，这可能归因于虹膜在水平子午线上的机械限制。
