Managements of vertical gas breakthrough in femtosecond laser assisted LASIK

Dear Editor,Femtosecond laser(FSL)assisted laser in situ keratomileusis(LASIK)has been popularized because of its greater accuracy and predictability.But FSL also have some unique complications especially some gas bubble related complications[1].Vertical gas breakthrough(VGB)is a rare and serious complication during flap creation.Some surgeons had reported that VGB was treated with microkeratome[2]or photorefractive keratectomy[3].To our knowledge,FSL-LASIK has not been reported as a remedy fort VGB(from PubMed).We present a VGB case who was successfully salvaged using FSL-LASIK.
