Abstract

Purpose: To compare the visual outcomes of simple high myopia (HM) and mild pathologic myopia (PM) following implantation of a trifocal intraocular lens (IOL), and investigate the influence of fundus structures.

Methods: We retrospectively studied 63 high myopic eyes of 63 patients underwent femtosecond laser-assisted cataract surgery with implantation of AT LISA tri 839MP IOL (Carl Zeiss Meditec AG, Germany) between July 2020 and September 2024. 34 eyes in the HM group and 29 eyes in the PM group. Main visual outcomes including monocular corrected distance (4 m, CDVA), distance-corrected intermediate (80 cm, DCIVA), distance-corrected near (40 cm, DCNVA) visual acuity, defocus curves, and subjective refraction. Optical coherence tomograph was employed to evaluate macular tilt degree (MTD), central foveal thickness, and subfoveal choroidal thickness. Multiple linear regression analysis was used to evaluate the independent predictors of visual acuity in the PM group.

Results: The CDVA, DCIVA, and DCNVA were 0.00 ± 0.00, 0.08 ± 0.05, and 0.09 ± 0.07 logarithm of the minimum angle of resolution (logMAR) in the HM group, 0.02 ± 0.05, 0.15 ± 0.09, and 0.17 ± 0.09 logMAR in the PM group, respectively. In the PM group, mean MTD was 17.13 ± 6.79°. The MTD demonstrated a significant predictive effect on CDVA (regression coefficient: 0.005; P = 0.026) and DCNVA (regression coefficient: 0.015; P = 0.003).

Conclusion: Trifocal IOL implantation yielded favorable visual outcomes in simple high myopic eyes, though results were comparatively poorer in PM cases. MTD was associated with the expected visual outcomes.

轻度病理性近视三焦人工晶状体植入术：视力结果及眼底结构的影响。

目的：比较单纯性高度近视（HM）和轻度病理性近视（PM）植入术后的视力结果，并探讨眼底结构的影响。方法：回顾性研究2020年7月至2024年9月63例高度近视患者的63只眼，这些患者接受飞秒激光辅助白内障手术并植入AT LISA三颗839MP人工晶体（德国卡尔蔡司医学股份公司）。HM组34眼，PM组29眼。主要视力指标包括单眼矫正距离（4 m， CDVA）、距离矫正中间距离（80 cm， DCIVA）、距离矫正近距离（40 cm， DCNVA）视力、离焦曲线和主观屈光度。采用光学相干断层扫描评估黄斑倾斜度（MTD）、中央凹厚度、中央凹下脉络膜厚度。采用多元线性回归分析评估PM组视力的独立预测因素。结果：HM组的CDVA、DCIVA、DCNVA分别为最小分辨角（logMAR）的0.00±0.00、0.08±0.05、0.09±0.07对数，PM组的CDVA、DCIVA、DCNVA分别为0.02±0.05、0.15±0.09、0.17±0.09对数。PM组平均MTD为17.13±6.79°。MTD对CDVA有显著的预测作用(回归系数：0.005；P = 0.026)和DCNVA(回归系数：0.015；p = 0.003)。结论：单纯性高度近视患者植入术效果较好，而PM患者植入术效果较差。MTD与预期的视觉结果相关。
