Laser in situ keratomileusis (LASIK) is a rapidly evolving ophthalmic surgi
cal procedure. Several anatomic and refractive complications have been iden
tified. Anatomic complications include corneal flap abnormalities, epitheli
al ingrowth, and corneal ectasia. Refractive complications include unexpect
ed refractive outcomes, irregular astigmatism, decentration, visual aberrat
ions, and loss of vision. Infectious keratitis, dry eyes, and diffuse lamel
lar keratitis may also occur following LASIK. By examining the etiology, ma
nagement, and prevention of these complications, the refractive surgeon may
be able to improve visual outcomes and prevent vision-threatening problems
. Reporting outcomes and mishaps of LASIK surgery will help refine our appr
oach to the management of emerging complications. (C) 2001 by Elsevier Scie
