The goal of a cataract operation is to achieve an optimal outcome, which includes a round and functioning pupil. The goal of this study was to analyze the influence of cataract operations on pupils that appear to be normal on slit-lamp examination postoperatively.
A videopupillography was performed on 47 eyes of 47 patients after phacoemulsification without complications in the first eye, and on 12 eyes of 12 patients after phacoemulsification without complications in the second eye.
After surgery, the first eyes showed a significantly more constricted pupil compared to the non-operated eye independently of the stage of irritation. After surgery of the second eye, this was only observed under near dark conditions.
Even the morphologically normal pupil shows a change in motility postoperatively. We believe that the reason for this is the mechanical manipulation of the iris during cataract operation. During this, the sensitive dilator muscle of the pupil is affected, leading to temporary or permanent changes in pupillary function. The change in motility of the contralateral, non-operated eye cannot be easily explained. The pupil size is important for the visual process and alteration of its function allows an evaluation of the quality of the operation.
白内障手术的目标是实现最佳效果，其中包括一个圆形且功能正常的瞳孔。本研究的目的是分析白内障手术对术后裂隙灯检查时看似正常的瞳孔的影响。
对47例患者的47只第一眼行超声乳化且无并发症后的眼睛进行了视频瞳孔描记术，对12例患者的12只第二眼行超声乳化且无并发症后的眼睛进行了视频瞳孔描记术。
术后，与未手术眼相比，第一眼无论刺激阶段如何，瞳孔均明显更缩小。第二眼手术后，仅在接近黑暗的条件下观察到这种情况。
即使形态正常的瞳孔术后也会出现运动性改变。我们认为其原因是白内障手术期间对虹膜的机械操作。在此过程中，瞳孔敏感的扩张肌受到影响，导致瞳孔功能出现暂时或永久性改变。对侧未手术眼运动性的改变难以解释。瞳孔大小对视觉过程很重要，其功能改变有助于评估手术质量。
