Microcapillary sign of flap alignment in femtosecond laser-assisted in situ keratomileusis
نویسندگان
چکیده
We present an observational sign that ensures perfect alignment during femtosecond laser-assisted in situ keratomileusis (FS LASIK). Alignment is assured when a microsponge is used to dry the flap and the area of dryness exceeds the area of direct touch of the microsponge. The area might even reach the whole circumference of the flap at the first touch. This sign of alignment can be explained by microcapillary action. This sign was not elicited in flaps created by a microkeratome.

Rescue of Primary Incomplete Microkeratome Flap with Secondary Femtosecond Laser Flap in LASIK
For laser-assisted in situ keratomileusis (LASIK) retreatments with a previous unsuccessful mechanical microkeratome-assisted surgery, some surgical protocols have been described as feasible, such as relifting of the flap or the creation of a new flap and even the change to a surface ablation procedure (photorefractive keratectomy (PRK)). This case shows the use of femtosecond technology for th...

Purpose. To report the incidence and outcomes of anterior chamber gas bubble formation during femtosecond laser flap creation for laser-assisted in situ keratomileusis (LASIK). Methods. The charts of 2,886 consecutive eyes that underwent femtosecond LASIK from May 2011 through August 2014 were retrospectively reviewed. The incidence, preoperative characteristics, intraoperative details, and pos...

PURPOSE To describe stromal changes after a femtosecond laser laser-assisted in situ keratomileusis (LASIK) flap was created but not separated. DESIGN Case report. METHODS As part of a randomized paired-eye study comparing LASIK flap creation by a femtosecond laser to a mechanical microkeratome, a femtosecond laser flap was successfully created on one eye of one patient, but the flap was no...

BACKGROUND/PURPOSE To evaluate the efficacy of autologous serum eye drops for patients with recalcitrant laser-assisted in situ keratomileusis (LASIK)-induced neurotrophic epitheliopathy (LINE) unresponsive to conventional treatment, and to determine the possible predisposing risk factors of these patients. METHODS We enrolled 10 consecutive patients (20 eyes) undergoing femtosecond-assisted ...

PURPOSE OF REVIEW Methods of flap creation have changed over the years from the evolution of the mechanical microkeratome to the introduction of the IntraLase femtosecond laser keratome, both of which have different mechanisms of action to create corneal resections. Previous studies report the advantages and disadvantages of the mechanical microkeratome and the IntraLase femtosecond laser. The ...
