OBJECTIVE To compare changes in subbasal nerve density and corneal sensitivity after laser in situ keratomileusis (LASIK) with the flap created by a femtosecond laser (bladeless) vs a mechanical microkeratome. DESIGN In a randomized paired-eye study, 21 patients received myopic LASIK with the flap created by a femtosecond laser in one eye and by a mechanical microkeratome in the fellow eye. E...

We describe the use and safety of prednisolone acetate eyedrops at the end of laser in situ keratomileusis (LASIK) to aid proper positioning of the corneal flap. The LASIK flap is created using the preferred technique. Following laser ablation and flap repositioning, one drop of prednisolone acetate is instilled on the eye. This delineates the flap "gutters" and allows perfect flap positioning ...

Progressive post-LASIK keratectasia (PPLK) is a progressive deformation of corneal anatomy that occurs rarely but may have severe consequences. Using the scientific literature and new hypotheses, we attempted to determine whether PPLK is a biomechanical result of laser in situ keratomileusis (LASIK), a chronic disease process affecting individuals predisposed to the condition, or a combination ...

PURPOSE To report and document a case of successful rainbow glare correction using undersurface ablation of the LASIK flap. METHODS A 33-year-old woman was treated bilaterally for myopia using femtosecond laser-assisted LASIK with the FS200 femtosecond laser (Alcon Laboratories, Inc., Fort Worth, TX). Postoperatively, she complained of rainbow glare in her right eye, and presented some residu...

PURPOSE To report 4 cases of flap margin-related corneal ulcer that developed 5 years after laser in situ keratomileusis (LASIK) procedures. METHODS We retrospectively documented the clinical and laboratory characteristics of all patients between 2004 and 2008 who presented with LASIK-related corneal ulcer that appeared >5 years postoperatively. The 4 patients who had this condition were 25-,...

A 30-year-old man who had laser in situ keratomileusis (LASIK) for myopia 1 year earlier developed a corneal perforation in the left eye from a boa constrictor. The patient presented to the emergency room, and a small corneal perforation just outside the visual axis was diagnosed within the LASIK flap. Cyanoacrylate adhesive was used to close the corneal perforation. The patient went on to full...

TEN years after some of the first photorefractive keratectomy (PRK) and laser-assisted in situ keratomileusis (LASIK) surgeries, patients are showing stable corneas and visual results, a Spanish study confirms. Jorge L Alio MD, PhD,Vissum Instituto Oftalmologico de Alicante,Alicante, Spain, reviewed the long-term results of 200 eyes that had undergone laser refractive surgery. The eyes were tre...

In this work we try to understand the real effect of increase in aberrations after Femto-LASIK surgery on patient’s final visual quality, specifically when acuity measurement is considered. A clinical study with 37 eyes 20 patients that underwent myopic and different personalized eye model simulations were carried out. study, correlations between pre- postoperative parameters analysed. Eye (bas...
