Understanding disability glare: light scatter and retinal illuminance as predictors of sensitivity to contrast [PDF]

open access: yes, 2015
The presence of a bright light in the visual field has two main effects on the retinal image: reduced contrast and increased retinal illuminance due to scattered light; the latter can, under some conditions, lead to an improvement in retinal sensitivity.

Queratotomía radial versus miniqueratotomía radial: Experiencia en el Hospital "Ramón Pando Ferrer" Radial keratotomy versus radial minikeratotomy: Experience in "Ramón Pando Ferrer" Hospital

open access: yesRevista Cubana de Oftalmología, 2000
La miniqueratotomía radial se viene realizando desde 1995. Se plantea que incisiones más cortas tienen el mismo efecto y producen menos debilidad corneal, ya que disminuye la susceptibilidad a sufrir complicaciones graves provenientes de traumas de la ...

Radial keratotomy.

open access: yesFortschritte der Ophthalmologie : Zeitschrift der Deutschen Ophthalmologischen Gesellschaft, 1991
Radial keratotomy is effective for correcting low-grade myopia. The predictability is best for myopia that is less than 4 diopters. If the procedure is well performed, the rate of complications remains low. There is not always good correlation between refraction and keratometric changes because of correction errors, which are the main complication ...
