140 Copyright © SLACK Incorporated Correspondence Flap Thickness in Femtosecond Laser

Recently, new femtosecond laser platforms have been developed to perform both corneal LASIK flaps and femtosecond laser-assisted cataract surgery. For this reason, we read with great interest the article by Juhasz et al.,1 which was the first study to evaluate the visual outcomes and flap thickness accuracy of the new LenSx multifunctional femtosecond laser system (Alcon Laboratories, Fort Worth, TX). Although the authors provided good visual results and a high flap thickness predictability with the LenSx device, it is noteworthy that they performed a targeted thick cor-neal flap of 140 µm in all cases. We have to take into account that the IntraLase femtosecond laser (Abbott Medical Optics, Inc., Santa Ana, CA), which is con-sidered the gold standard of corneal femtosecond la
