To evaluate the ultrastructure of the cornea of Avellino corneal dystrophy (ACD) exacerbated by LASIK.
Three ACD patients with exacerbation of granular corneal deposits after LASIK underwent surgical removal of the corneal flap. The corneal flap was processed for scanning electron microscopy (SEM).
SEM of all patients showed abnormal granular clusters in the fibrils of the corneal flap.
Laser in situ keratomileusis induces corneal collagen abnormalities and adhesions of granular material in ACD patients.
