Optical aberration from the positioning holes of a posterior chamber intraocular lens was encountered in three patients with wide spontaneous dilation of the pupil in scotopic conditions. One patient had a cataract extraction in his fellow eye with implantation of a posterior chamber lens without positioning holes in its optical portion and has not encountered any aberrations in that eye. We suggest that in such patients, careful preoperative measurement of the pupillary size in a dark room should be done and lenses without positioning holes on the optic should be used to prevent optical aberrations.
三名患者在暗适应条件下瞳孔出现自发性明显散大，其后房型人工晶状体定位孔出现了光学像差。其中一名患者的另一只眼睛接受了白内障摘除手术并植入了光学部没有定位孔的后房型人工晶状体，该眼未出现任何像差。我们建议，对于此类患者，术前应在暗室中仔细测量瞳孔大小，并使用光学部没有定位孔的人工晶状体以防止光学像差。
