Thin flap is the tendency of laser in situ keratomileusis / 眼科

ABSTRACT

Up to date,excimer laser in situ kerratomileusis(LASIK) has being the main stream in the corneal refractive surgery.The main cause of iatrogenic kerateotasia and keratoconus is the failure of corneal biomechanics that is one of the most severe complications of LASIK.Thin flap will be the tendency of LASIK since it can preserve more under-flap stromal tissue to keep more intact corneal structure.With the femtosecond laser system that has advantages comparing with the mechanical microkeratome,we can customize the thin flap.There are some unique features in thin flap manipulation and post-operational healing process.The nomogram of the excimer laser and the post-OP medicine should be adjusted.
