摘　　要：目的探究有晶状体眼后房型人工晶体(ICL)植入术后患者的瞳孔直径大小与视觉质量、高阶像差的相关性分析。方法随机选取2021年3月至2023年5月在我院进行诊治的103例行ICL植入术的高度近视患者作为研究对象进行回顾性分析研究。按照患者瞳孔直径大小分为<4 mm组(暗视瞳孔直径)54例及≥6 mm组明视瞳孔直径49例。观察患者在明视、暗视环境下瞳孔直径大小变化。分析暗室环境下不同瞳孔直径大小患者视觉质量、高阶像差及对比敏感度变化。结果相较于术前,术后明视环境下瞳孔直径增大,暗视环境下瞳孔直径减小,明暗差减小(P<0.05)。与<4 mm组相比,≥6 mm组患者斯特列尔比及调制传递函数截止频率均升高(P<0.05)。与<4 mm组相比,≥6 mm组患者总高阶像差、三叶草差及球差升高(P<0.05);2组慧差对比差异无统计学意义(P>0.05)。与<4 mm组相比,≥6 mm组患者在空间频率为3 c/deg、6 c/deg、12 c/deg及18 c/deg时对比敏感度升高(P<0.05)。结论ICL植入术后患者明暗视瞳孔差减小,且瞳孔直径大小与视觉质量、高阶像差及对比敏感度具有相关性。瞳孔直径越大,高阶像差越大,对比敏感度越大,视觉质量越高。Objective To investigate the correlation analysis of pupil diameter size with visual quality and higher order aberrations in patients after posterior chamber IOL(ICL)implantation in lens-bearing eyes.Methods One hundred and three patients with high myopia who underwent ICL implantation in our hospital from March 2021 to May 2023 were randomly selected for retrospective analysis.According to the size of the pupil diameter,the patients were divided into 54 cases in the<4 mm group(dark-sighted pupil diameter)and 49 cases in the≥6mm group(bright-sighted pupil diameter).The change in pupil diameter size of the patients under bright and dark vision environments was observed.The visual quality,higher-order aberration,and contrast sensitivity of patients with different pupil diameters were analyzed in the darkroom environment.Results Compared with the preoperative period,the pupil diameter was larger in the bright-vision setting,and smaller in the dark-vision setting,and the light-dark difference was reduced after surgery(P<0.05).Strehl′s ratio and modulation transfer function cut-off frequency was significantly higher in the≥6 mm group compared with the<4 mm group(P<0.05).Compared with the<4 mm group,the total higher-order aberration,cloverleaf aberration,and spherical aberration were higher in the≥6 mm group(P<0.05).The difference in the coma difference between the two groups was not statistically significant(P>0.05).Compared with the<4 mm group,patients in the≥6 mm group had higher contrast sensitivity at spatial frequencies of 3 c/deg,6 c/deg,12 c/deg,and 18 c/deg(P<0.05).Conclusion The pupillary aberration between dark and light vision decreased after ICL implantation,and the size of the pupil diameter correlated with visual quality,higher-order aberrations,and contrast sensitivity.The larger the pupil diameter,the greater the higher order aberration,the greater the contrast sensitivity,and the higher the visual quality.
