Abstract

Objective: This study aimed to evaluate the effect of the implantation meridian (horizontal or vertical) of the Eyecryl phakic intraocular lens (pIOL) on ocular residual astigmatism (ORA), anterior chamber depth (ACD), and vault height.

Methods: A total of 44 eyes were retrospectively analyzed and divided into two groups based on the meridian of pIOL implantation: horizontal (n = 16) and vertical (n = 28). Keratometry, refractive astigmatism, ORA, ACD, and vault height were compared between the groups.

Results: A significant postoperative increase in ORA was observed in the horizontal group (P < 0.001), whereas ORA remained stable in the vertical group. ACD reduction was more pronounced in the horizontal group (P = 0.006). No significant difference was found between the groups in terms of changes in vault height (P > 0.05).

Conclusion: In this study, ORA values remained stable in the group with vertically implanted pIOLs during both the preoperative and postoperative periods. This finding suggests that vertical implantation provides more stable refractive outcomes.

垂直晶状体人工晶状体植入术比水平晶状体植入术具有更好的散光稳定性：回顾性分析。

目的：探讨眼晶状体人工晶状体（pIOL）植入经络（水平或垂直）对眼残余散光（ORA）、前房深度（ACD）和穹窿高度的影响。方法：回顾性分析44只眼，根据pIOL植入术经络分为水平（16只）和垂直（28只）两组。比较两组患者角膜光度、屈光散光、ORA、ACD和拱顶高度。结果：水平组的ORA术后明显升高（P < 0.001），而垂直组的ORA术后保持稳定。水平组ACD降低更为明显（P = 0.006）。各组间跳高变化差异无统计学意义（P < 0.05）。结论：在本研究中，垂直植入piol组的ORA值在术前和术后均保持稳定。这一发现表明垂直植入提供了更稳定的屈光结果。
