Abstract

In certain embodiments, refractive correction includes controlling a focus of pulsed laser radiation having ultrashort pulses. A channel is created with the pulsed laser radiation to facilitate separation of the lenticule from the eye. A posterior incision is created with the pulsed laser radiation to form a posterior side of the lenticule. An anterior incision is created with the pulsed laser radiation to form an anterior side of the lenticule.
