摘要: 目的 分析圆锥角膜眼配戴硬性透气性接触镜(RGPCL)后残余像差对视觉质量的影响。 方法 选择圆锥角膜患者20例,配戴RGPCL一个月后,采用自适应光学系统实时动态测量、并闭环矫正4 mm瞳孔直径下圆锥角膜RGPCL配戴眼的残余像差。测量并计算残余像差矫正前后对比敏感度功能(CSF)值(空间频率2、4、8、16、32 cpd)。根据残余像差矫正前后的波前像差值,计算调制传递函数(MTF)值(空间频率2、4、8、16、32 cpd)。计算各个空间频率的MTF获益值和CSF获益值。 结果 与残余像差矫正前相比,残余像差矫正后,圆锥角膜RGPCL配戴眼在各个空间频率下的MTF值均有提高(P<0.001);在2、4、8、16 cpd空间频率下,CSF值有提高(P<0.05);在32 cpd空间频率下,残余像差矫正前后CSF值差异无统计学意义(P>0.05)。圆锥角膜RGPCL配戴眼在低空间频率(2 cpd)和中空间频率(4、8、16 cpd)下,CSF获益值与矫正前残余总像差的均方根(RMS)值呈正相关(r值分别为0.591、0.552、0.711、0.783,P<0.05);高空间频率(32 cpd)下,CSF获益值与矫正前残余总像差RMS值无关(P>0.05)。圆锥角膜RGPCL配戴眼在残余像差矫正后,随着空间频率的增加,MTF获益值逐渐增加,中空间频率CSF获益值高于低、高空间频率。 结论 圆锥角膜患者配戴RGPCL后,在4 mm瞳孔直径下,残余像差对眼球光学质量及低、中频的空间CSF存在影响。
