Femtosecond assisted keratopigmentation (FAK) with a 5-millimeter diameter aperture does not affect ocular examination

Abstract

Aim to assess the feasibility of performing a screening of ocular pathologies after Femtosecond laser Assisted Keratopigmentation (FAK) procedure in normal eyes with the aid of multimodal imaging technologies. Design A Retrospective cohort study. Participants Thirty consecutive international patients (60 eyes) who underwent FAK for purely aesthetic reasons were chosen for this study. Methods Data from medical records of 30 consecutive patients were retrieved after performing tests 6 months after surgery. Clinical examinations were performed by three ophthalmologists. Main outcome measures The main purpose of this study was to see if routine examinations are feasible in patients operated on by the FAK and if the results can be interpreted as easily as in non-operated patients. Results Sixty eyes of thirty consecutive patients that underwent a screening of ocular pathologies at 6 months post FAK were included. 60% were female and 40% were males. Mean age was 36 years +/− 12 years. Screening of ocular pathologies using multimodal imaging tests or clinical examination was performed without any difficulties in acquisition or interpretation in 100% of patients (n = 30) except the endothelial cell count of the corneal periphery which was not possible. The direct examination of the iris periphery was possible at the slit lamp through the translucid pigment. Conclusions The screening of ocular pathologies after purely aesthetic FAK surgery is feasible, except for pathologies of the peripheral posterior cornea.
