Pros and cons of femtosecond LASIK.

Pros	Cons
− Greater predictability of flap thickness creation − Possibility to redo flap creation (also with different depth settings) − Less common complications associated with flap creation (e.g., flap slippage) − A more versatile tool—possibility to employ small-incision lenticule extraction (SMILE) in some platforms or, e.g., to create corneal pockets	− Uncommon complications specific for femtosecond lasers include opaque bubble layer, vertical gas breakthrough, and transient light sensitivity syndrome − Higher rate of diffuse lamellar keratitis − High cost for the laser and its maintenance
