目的：研究单片AcrySof（型号SA60和SN60； Alcon, Fort Worth, Texas， USA）人工晶状体（iol）的闪烁现象。设计：观察性、纵向研究。方法：在术后12、24和36个月连续检查SA60患者；SN60患者在手术后12个月接受检查。对最小分辨率角的最佳校正对数进行了视觉灵敏度、眩光测试、对比灵敏度和波前分析。排除任何具有可能影响视觉质量的病理特征的患者。所有的人工晶状体都被拍照，并通过计算机程序分析闪烁的大小和密度。结果：所有iol均有闪烁，尺寸、密度和严重程度指数（尺寸X密度）均与视力、眩光测试或波前分析结果无关。高空间分辨率对比敏锐度（斑块D）与严重程度指数有边缘相关性（P.06），随着时间的推移也有相关性（P.04）。结论：所有研究的人工晶状体均有闪烁。高空间分辨率对比敏感度影响和严重程度随时间的进展值得进一步研究。
PURPOSE: To study glistenings in single,piece AcrySof (models SA60 and SN60; Alcon, Fort Worth, Texas, USA) intraocular lenses (IOLs).DESIGN: Observational, longitudinal study.METHODS: Consecutive patients with the SA60 were examined at 12, 24, and 36 months after surgery; those with the SN60 were examined 12 months after surgery. Best-corrected logarithm of the minimum angle of resolution visual acuity, glare testing, contrast sensitivity, and wavefront analysis were performed. Any patient with pathologic features likely to impact visual quality was eliminated. All IOLs were photographed, and glistenings were analyzed for size and density by a computer program.RESULTS: All IOLs had glistenings, and neither size, density, nor severity index (size X density) correlated with acuity, glare testing, or wavefront analysis results. High spatial resolution contrast acuity (patch D) had a borderline correlation (P.06) with severity index, as did progress over time (P.04).CONCLUSIONS: All IOLs studied had glistenings. High spatial resolution contrast sensitivity impact and severity progression over time deserve further study.
