目的 :观察波前像差引导的LASIK术矫正人眼像差后的效果 ,以确定人眼是否可获得超过一般的视敏度。方法 :波前像差引导的LASIK手术对 15只眼矫正近视和散光 ,同时矫正眼球的像差。结果 :手术后 1个月时 ,4只眼 (占 2 7% )获得了 2 0 /10以上的超常视力。波前像差的均方根值从 0 .6增加到 2 .3,与视觉敏感度的提高呈显著性相关 (P <0 .0 5 )。结论 :像差的矫正虽然还不能最令人满意 ,但这些结果表明 ,眼球的像差使人眼视敏度受限制 ,而通过手术矫正可获得超过一般的视敏度。
OBJECTIVE: To observe the effect of wavefront-guided LASIK on the correction of human eye aberrations to determine if the human eye can acquire more than the usual visual acuity. Methods: LASIK guided by wavefront aberration corrected myopia and astigmatism in 15 eyes and corrected the aberration of the eye. Results: At 1 month after surgery, 4 eyes (27%) had more than 20% of abnormal vision. The mean square value of wavefront aberrations increased from 0.6 to 2.3, which was significantly correlated with the improvement of visual acuity (P <0.05). CONCLUSIONS: Although aberration correction is not yet the most satisfactory, these results suggest that ocular aberrations limit the visual acuity of the eye and surpass the general visual acuity achieved by surgical correction.
