摘要
目的在共焦显微镜观察下比较激光原位角膜磨镶术(LASIK)和激光上皮瓣下角膜磨镶术(LASEK)术后角膜神经再生的变化。方法LASIK16例(32眼),LASEK13例(26眼)。分别于术前、术后3月和术后6月进行中央角膜组织共焦显微镜检查,并测定泪膜破裂时间(BUT)。结果LASIK和LASEK术后上皮基底膜下神经纤维数量的差异有统计学意义。两组中,BUT与角膜神经再生均无明显相关关系。结论LASEK术后角膜神经再生明显快于LASIK术后。
Objective To compare changes in corneal nerve fibers by confocal microscopy after laser - assisted in situ keratomileusis （LASIK） and laser epithelial keratomileusis （LASEK）. Methods The study included 32 eyes （16 patients） that had undergone LASIK and 26 eyes （13 patients） that had undergone LASEK. Confocal microscopic data of the central cornea and tear film breakup time （BUT） were examined before surgery and at 3,6 months after LASIK or LASEK treatment. Results The number of subbasal nerve fibers was different in the LASIK and LASEK groups. The tear film breakup time did not correlate with corneal nerve regeneration in the two groups. Conclusions Corneal nerve regeneration was faster in LASEK-operated eyes than in LASIK-operated eyes.
