Comparison of corneal flap thickness using a FS200 femtosecond laser and a moria SBK microkeratome [PDF]
International Journal of Ophthalmology, 2014 AIM: To evaluate differences in flap thickness resulting from use of an Alcon Wavelight FS200 femtosecond laser and a MORIA SBK microkeratome when making a 110-μm-thick corneal flap and to identify the potential factors that affect corneal flap thickness.

Unexpectedly high corneal flap thickness and ectasia after mechanical LASIK
Revista Brasileira de Oftalmologia, 2023 LASIK is a refractive surgical procedure in which a corneal flap is created to expose the corneal stromal bed. Preoperative estimation of corneal flap thickness is necessary to calculate the percentage tissue altered in LASIK, an important quantitative ...

Biomechanical corneal changes induced by different flap thickness created by femtosecond laser [PDF]
Clinics, 2011 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 ...

Effects of Aberrant Pax6 Gene Dosage on Mouse Corneal Pathophysiology and Corneal Epithelial Homeostasis [PDF]
, 2011 Background: Altered dosage of the transcription factor PAX6 causes multiple human eye pathophysiologies. PAX6(+/-) heterozygotes suffer from aniridia and aniridia-related keratopathy (ARK), a corneal deterioration that probably involves a limbal ...

Aerodynamic and performance characteristics of a passive leading edge Kruger flap at low Reynolds numbers [PDF]
, 2012 An experimental and numerical study was performed on a Clark Y aerofoil with a 10% chord leading edge Kruger flap to examine its aerodynamic performance at Reynolds numbers of 0.6 × 106, 1 × 106, and 1.6 × 106, to help to identify the forces and ...

Effects of the LASIK flap thickness on corneal biomechanical behavior: a finite element analysis
BMC Ophthalmology, 2020 Background It is well known that the biomechanical properties change after LASIK refractive surgery. One reason is the impact of flap creation on the residual stroma. The results have revealed that the change is closely related with the flap thickness in
