摘要
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:χ2=2.397,P>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:χ2=10.85,P<0.01;夜间视物质量:χ2=10.85,P<0.01);术后效果满意率达到98.8%。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。
AIM：To observe visual quality after Q-guided aspheric ablation and standard ablation in LASIK and to evaluate the clinical effects of Q-guided aspheric ablation. METHODS：From January, 2008 to May, 2008, 46 patients （88 eyes）whose equivalent spherical diameter were lower than -12. 00D underwent aspheric ablation and standard ablation in LASIK and were followed up, and they were divided into two groups according to preoperative refractive diopter, refractive diopter of group A 〈 -6.00D ,- 6.00D to -12.00D of group B. Naked vision, Q-value, glare in night, night vision and satisfaction rate of the two groups were compared 1 month after opera-tion. RESULTS： There were no significant differences in postoperative uncorrected visual acuity （UCVA） and Qvalue of all eyes in these subgroups of each group （ UCVA：t=1.18,P〉0.05;t=0.62,P〉0.05;Q-value. t =-0.93, P〉 0.05; t =-0. 372, P〉 0.05）. There were no significant differences of glare in night, night vision of these subgroups in A group （χ^2 = 2. 397,P〉 0.05; χ^2= 1. 263,P〉 0.05）, but the condition in group B was reverse. （χ^2= 10. 85, P〈 0.05 ;χ^2 = 10.85, P〈 0.05）. Satisfaction rate was 98.8%.
