Purpose：To
investigate the mechanisms of the dry eye symptoms induced by the LASIK
procedure as well as to find out the proper resolutions for the
patients.
Method :
We
retrospectively investigate three post –LASIK induced severe dry eyes
cases
for the past one year .One female as
well as two males went through the precise pre- LASIK examination
including Schirmer tset 1 being greater than 10 mm..
Result :
Dryness with blurred or fluctuating vision were noted with these patients
. LASIK-induced neurotrophic epitheliopathy ( LNE ) as well as epithelium
ingrowth were developed with victims’ cornea . Either non preserved or a
transiently preserved artificial tear were used for the treatment .
Besides , punctum plug inserting as well as Genteal Gel lubricating were
also observed for the options of the treatments .
Conclusion: LASIK-induced neurotrophic epitheliopathy (LNE) is triggered by the loss of neurotrophic influence for the corneal sensory nerves that are severed during flap formation . Decrease of both tear quantity and quality are noted 3 to 6 months after LASIK. Recurrent corneal erosion was major concern with our investigation.
