PURPOSE
To report the clinical outcomes after implantation of a small-aperture intraocular lens (IOL) and a partial aniridia ring in three patients with traumatic iris defects.
OBSERVATIONS
The corrected distance visual acuity (CDVA), irregular astigmatism, and glare improved in all patients. In one patient, the monocular defocus curve showed a visual acuity (VA) of 0.30 logMAR or better from 1.0 to -1.5 D, and the halo size and intensity were 5 and 10 (on a scale from 0 to 100), respectively, and the glare size and intensity were 23 and 16 (on a scale from 0 to 100), respectively.
CONCLUSIONS AND IMPORTANCE
The pinhole effect of the small-aperture IOL helped considerably decrease irregular astigmatism and improve visual acuity. The partial aniridia implant also contributed to the reduction of the glare symptoms, while allowing a sufficient fundus assessment. The combined implantation of the small-aperture IOL and the partial aniridia device, therefore, presents an effective option for improvement of the visual symptoms in patients with traumatic iris defects.
目的
报告三例外伤性虹膜缺损患者植入小孔径人工晶状体（IOL）和部分无虹膜环后的临床结果。
观察结果
所有患者的矫正远视力（CDVA）、不规则散光和眩光均有所改善。一名患者的单眼散焦曲线显示，在1.0至 -1.5 D时视力（VA）为0.30 logMAR或更好，光晕大小和强度分别为5和10（范围为0至100），眩光大小和强度分别为23和16（范围为0至100）。
结论与意义
小孔径IOL的针孔效应有助于显著降低不规则散光并提高视力。部分无虹膜植入物也有助于减轻眩光症状，同时允许进行充分的眼底评估。因此，小孔径IOL和部分无虹膜装置的联合植入为改善外伤性虹膜缺损患者的视觉症状提供了一种有效的选择。
