Abstract

Abstract : 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. 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. Results: In the pilot series of 20 eyes, flap creation was possible in each case. The mean preoperative manifest refractive spherical equivalent was À−4.22 D (SD±61.22 D). The postoperative spherical equivalent refraction was À−0.1 D (SD±60.26 D) at 1 month, À−0.22 D (SD±60.24 D) at 3 months and À−0.15 D (SD±60.16 D) 12 months after surgery. Conclusions: Femto-LASIK with this new laser system showed high levels of safety, stability and efficacy without any enhancement. Clinical trials registration: http://www.dimdi.de .
