Flogosi post-trapianto di cornea [PDF]

open access: yes, 2013
Il Trapianto di Cornea, o Cheratoplastica, che prevede la sostituzione sub-totale della cornea mediante un innesto circolare di tessuto omologo (lembo), rappresenta la procedura d’elezione per il trattamento di diverse patologie corneali congenite o

Corneal Biomechanics in Ectatic Diseases: Refractive Surgery Implications. [PDF]

open access: yes, 2017
BACKGROUND: Ectasia development occurs due to a chronic corneal biomechanical decompensation or weakness, resulting in stromal thinning and corneal protrusion. This leads to corneal steepening, increase in astigmatism, and irregularity.

Effects of differenta mitomycin C concentrations on laser-assisted subepithelial keratectomy

open access: yesExperimental and Therapeutic Medicine, 2014
The aim of the present study was to determine the effect of different concentrations of mitomycin C (MMC) administered intraoperatively during laser-assisted subepithelial keratectomy (LASEK) surgery. A total of 261 patients (496 eyes) were randomly divided into two groups: 0.04% MMC treatment group consisting of 133 patients (245 eyes) and the 0.02 ...

Laser-assisted subepithelial keratectomy (LASEK) versus laser-assisted in-situ keratomileusis (LASIK) for correcting myopia

open access: yesCochrane Database of Systematic Reviews, 2017
Near-sightedness, or myopia, is a condition in which light rays entering the eye along the visual axis focus in front of the retina, resulting in blurred vision. Myopia can be treated with spectacles, contact lenses, or refractive surgery. Options for refractive surgery include laser-assisted subepithelial keratectomy (LASEK) and laser-assisted in-situ
