Keratorefractive lenticule extraction (KLEx) versus femtosecond laser-assisted in situ keratomileusis (FS-LASIK) for the treatment of myopia and compound myopic astigmatism: study protocol of a randomised clinical trial in Mexico [PDF]

BMJ Open
Introduction Kerato-lenticule extraction (KLEx) is a refractive surgery technique that, in contrast with femtosecond laser-assisted in situ keratomileusis (FS-LASIK), does not require the creation of a flap to correct refractive defects.
