目得：目的：比较LASIK术后干眼症患者泪点阻塞前后波前像差的变化。设计：前瞻性、对比性、非随机研究。分别在泪点塞植入前和植入后1个月进行波前像差测量，并与10例LASIK术后无干眼症的患者进行比较，两次测量间隔1个月。结果：LASIK术后干眼患者的泪点阻塞显著降低了总的、低阶的和高阶的波前像差，降低了47%到63%（P
PURPOSE: To compare the wavefront aberrations in post-laser in situ keratomileusis (LASIK) dry eye patients before and after punctal occlusion.DESIGN: Prospective, comparative, nonrandomized study.METHODS: Wavefront aberrometry was performed on 16 eyes of eight patients with dry eyes after LASIK surgery. Wavefront measurements were taken before and I month after punctal plug placement and compared with 10 eyes of post,LASIK patients without clinically dry eyes measured twice 1 month apart. Student t tests were used to assess the statistical significance of differences between pre, and post,punctal plug measurements.RESULTS: Punctal occlusion in the post-LASIK dry eye patients significantly reduced total, lower, and higher order wavefront aberrations by 47% to 63% (P
