简介：目的：通过对Q值调整非球面切削与标准化LASIK术后视觉质量的观察来分析Q值引导个性化切削技术的临床效果。方法：对2008-01/05等效球镜低于-12.00D的46例88眼进行非球面切削或标准化LASIK术后进行随访,按术前屈光度数将其分为A组（〈-6.00D）和B组（-6.00～-12.00D）两组,对比各组非球面切削与标准化LASIK术后1mo裸眼视力、Q值、夜间眩光、夜间视物质量及满意率（后3者采取问卷调查）。结果：A、B组内非球面切削与标准化LASIK术后裸眼视力差异无统计学意义（t=1.18,P〉0.05;t=0.62,P〉0.05）;A、B组内非球面切削与标准化LASIK术后Q值差异无统计学意义（t=-0.93,P〉0.05;t=-0.372,P〉0.05）;A组内非球面切削与标准化LASIK术后眩光、夜间视物质量差异无统计学意义（眩光：χ^2=2.397,P＆gt;0.05;夜间视物质量：χ2=1.263,P〉0.05）;B组内非球面切削与标准化LASIK术后眩光、夜间视物质量差异有统计学意义（眩光：χ^2=10.85,P〈0.01;夜间视物质量：χ^2=10.85,P〈0.01）;术后效果满意率达到98％。结论：非球面切削能明显改善-6．00D以上的术后主观视觉质量。
