Is your CORNEA thick enough for LASIK?


The doctor said my cornea’s are too thin for LASIK.  What does that mean?  In order to have LASIK surgery one’s corneas need to be the correct thickness.  This is very important.  In LASIK a cornea flap is created.  This corneal flap is typically around 160 microns thick.  Once the flap is created it is pulled back and the laser will reshape the cornea.  When the cornea is being reshaped, tissue is being removed.  There must be a minimum tissue remaining, bed tissue, to the cornea after the laser reshaping process.  The minimum bed thickness must be greater than 250 microns.  If the bed thickness is less the 250 microns this can increase risk of a complication called corneal ectasia where the cornea bulges out and causes significant distortions in one’s vision.  This can be devastating.

What is LASIK Eye Surgery (laser in situ keratomileusis)?


LASIK is a very common eye surgery procedure that can be used to correct myopia, hyperopia, and astigmatism. This procedure is widely use throughout the world and has been very successful with low complication rates.
