Background The aim of this study was to perform the first femtosecond laser cuts with a new prototype femtosecond laser, in vivo and to evaluate its safety, stability and efficacy. %26lt;br%26gt;Methods A LASIK cut was performed with a prototype 200 kHz femtosecond laser in both eyes of nine patients and one eye of two patients (20 individual eyes in total). A complete ophthalmic examination was performed preoperatively and postoperatively at 1, 3, 6 and 12 months after the procedure. %26lt;br%26gt;Results In the pilot series of 20 eyes, flap creation was possible in each case. The mean preoperative manifest refractive spherical equivalent was A-4.22 D (SD +/- 61.22 D). The postoperative spherical equivalent refraction was A-0.1 D (SD +/- 60.26 D) at 1 month, A-0.22 D (SD +/- 60.24 D) at 3 months and A-0.15 D (SD +/- 60.16 D) 12 months after surgery. %26lt;br%26gt;Conclusions Femto-LASIK with this new laser system showed high levels of safety, stability and efficacy without any enhancement.
