高度近视并发性白内障术后屈光漂移及其相关因素分析

Analysis of Refractive Drift and Associated Factors Following Surgery for Complicated Cataracts in Patients with High Myopia

摘要: 目的：探讨高度近视并发性白内障患者术后屈光漂移的变化特征及其影响因素。方法：回顾性收集高度近视并发性白内障患者资料，详细记录其术后屈光漂移度数。通过比较术前与术后生物学测量参数的变化，进一步对屈光漂移量与各相关指标进行相关性分析。结果：高度近视并发性白内障术后普遍出现一定程度的远视漂移。屈光漂移程度与术前晶状体厚度呈负相关，与前房深度的变化呈正相关。结论：屈光漂移现象普遍存在于高度近视并发性白内障患者，但随着生物测量技术的不断进步以及人工晶体度数计算公式的持续优化，屈光漂移的程度有望逐步减轻。

Abstract: Objective: To investigate the characteristics and influencing factors of postoperative refractive drift in patients with high myopia complicated by cataract. Methods: We retrospectively collected clinical data from patients with high myopia complicated by cataract who underwent surgical intervention. The magnitude of refractive drift after surgery was recorded and ocular biometric parameters were compared before surgery and postoperatively. Additionally, correlation analyses were conducted to evaluate the relationship between and various associated factors. Results: A hyperopic shift was commonly observed following cataract surgery in patients with high myopia. The degree of refractive shift was negatively correlated with preoperative lens thickness and positively correlated with the change in anterior chamber depth. Conclusion: Refractive shift is a prevalent phenomenon in patients with high myopia undergoing cataract surgery. However, with ongoing advancements in ocular biometry and continuous refinement of intraocular lens power calculation formulas, the extent of refractive deviation is expected to diminish progressively.
