Three-dimensional LASIK flap thickness variability: topographic central, paracentral and peripheral assessment, in flaps created by a mechanical microkeratome (M2) and two different femtosecond lasers (FS60 and FS200)
PURPOSE To evaluate programmed versus achieved laser-assisted in situ keratomileusis (LASIK) flap central thickness and investigate topographic flap thickness variability, as well as the effect of potential epithelial remodeling interference on flap thickness variability. PATIENTS AND METHODS Flap thickness was investigated in 110 eyes that had had bilateral myopic LASIK several years ago (av...
متن کاملComparison of laser in situ keratomileusis flaps created by 3 femtosecond lasers and a microkeratome.
PURPOSE To evaluate the thickness and side-cut angle of laser in situ keratomileusis (LASIK) flaps created by 1 of 3 femtosecond lasers or a microkeratome using Fourier-domain optical coherence tomography (OCT). SETTING Department of Ophthalmology, Institute of Vision Research, Yonsei University College of Medicine, Seoul, Korea. DESIGN Comparative case series. METHODS Flap creation for b...
متن کاملFemtosecond LASIK flaps: excellent, but superior?
s 2012 begins, femtosecond lasers have been used for more than a decade to create LASIK fl aps. 1 Starting with a single model, these lasers have gone through multiple iterations, and now multiple competing technologies are available in the market place worldwide. In the United States, recent surveys demonstrate continued increasing market share. Now more than half of all LASIK procedures are p...
متن کاملMonolithic optofluidic ring resonator lasers created by femtosecond laser nanofabrication.
We designed, fabricated, and characterized a monolithically integrated optofluidic ring resonator laser that is mechanically, thermally, and chemically robust. The entire device, including the ring resonator channel and sample delivery microfluidics, was created in a block of fused-silica glass using a 3-dimensional femtosecond laser writing process. The gain medium, composed of Rhodamine 6G (R...
متن کاملBiomechanical corneal changes induced by different flap thickness created by femtosecond laser
OBJECTIVE To evaluate the impact of the creation of corneal flaps at different thicknesses on the biomechanical properties of swine corneas. METHOD Twelve swine eyes were obtained to form two groups: 100 μm flap thickness and 300 μm flap thickness. Each eye was submitted to the following examinations: raster topography to investigate corneal curvature alterations, ocular response analyzer to ...
