目的：对13只屈光度< -4.0 ~ -7.0的近视患者在LASIK手术后出现中枢性或下枢性角膜扩张症进行研究。方法：通过一系列lasik术前和术后的地形图和病例史来确定扩张的进展。结果：LASIK术后1周~ 27个月出现进行性扩张。这就需要佩戴硬隐形眼镜或穿透性角膜移植术。其中一只眼睛在光屈光性角膜切除术后几个月有所改善。术前1例患者2眼和1例患者1眼有潜伏性圆锥角膜。结论：激光原位角膜磨除术即使对低近视眼也可引起角膜永久性弱化和扩张。[J]中华白内障杂志；(C) 2000 ASCRS和ESCRS。
Purpose: To study 13 eyes with less than -4.0 to -7.0 diopters of myopia that developed central or inferior keratectasia after laser in situ keratomileusis (LASIK).Methods: The progress of the ectasia was determined by a series of pre- and post-LASIK topographies and the case histories.Results: Progressive ectasia developed from 1 week to 27 months after LASIK. This necessitated the wearing of hard contact lenses or penetrating keratoplasty. One eye improved for some months after photorefractive keratectomy retreatment. Two eyes in 1 patient and 1 eye in a second patient had latent keratoconus before surgery.Conclusion: Laser in situ keratomileusis can cause permanent weakening and ectasia of the cornea even in eyes with low myopia.
