LASIK

What is LASIK?

LASIK is an acronym for laser in situ keratomileusis, which means to reshape the cornea without disturbing the adjoining tissue. Translation of these Greek words: in situ means "in the natural or normal place," kerato means "cornea," and mileusis means "to shape".

Surgeons use a tiny high-precision instrument called a microkeratome to separate the layers of corneal tissue and create a thin flap on the surface of the eye. This flap is folded back and the excimer laser is guided to gently reshape the underlying tissue. The corneal flap is replaced leaving the eye almost untouched. The cornea's new shape is what improves vision. The quality of the corneal flap is crucial to minimizing complications and achieving excellent results. Many surgeons recognize that creating an exceptional high quality flap is 80% of the procedure's success.
