Prospective study To compare the effect on visual quality (light scattering) and dry eye between FS-LASIK and ReLEx Smile procedure.
30 subjects (60 eyes) underwent FS-LASIK, 30 subjects (60 eyes) undewent Smile. OQAS device (Visiometrics, Medeuronet) was used to evaluate light scattering (OSI) and dry eye preoperatively as well as 1 month and 3 months after surgery.
At 1 and 3 months, the OSI index in the FS-LASIK group was significantly higher than in the Smile group. Furthermore, concerning the tear film using the OQAS, the results showed that the dry eye increased significantly in the FS-LASIK group compared to the second group.
This study has shown that the ReLEx Smile procedure may result in less light scattering and dry eye than classical femtosecond lasik. This might be because Smile is a flapless procedure, inducing less topographic changes with biomechanical influence on spherical aberration induction and less inflammation with better corneal sensitivity after surgery.
