PURPOSE To evaluate in vitro the amoebicidal effects of riboflavin and ultraviolet A (UVA) collagen cross-linking. DESIGN Experimental study, laboratory investigation. METHODS Two different strains of Acanthamoeba species were tested identically. Four treatment groups were considered: group 1 consisted of 0.1% riboflavin and 30-minute UVA irradiation;(More)
PURPOSE To study the biomechanical effect of riboflavin-ultraviolet A irradiation (UVA)-induced collagen cross-linking (CXL) in porcine corneas using two different exposure times of 30 and 60 min. METHODS Seventeen enucleated porcine eyes were divided into three groups: group A, six eyes without any treatment, group B, six eyes treated by UVA CXL for 30(More)
Purpose. To examine biomechanical parameters of the cornea in myopic eyes and their relationship with the degree of myopia in a western healthy population. Methods. Corneal hysteresis (CH), corneal resistance factor (CRF), Goldmann correlated intraocular pressure (IOP), and corneal compensated IOP (IOPcc) were measured using the ocular response analyzer(More)
PURPOSE To determine the effect of the parameters related to limbal incisions (length, depth, optical zone, and so on) by revision of different nomograms and analyzing the outcomes of numerical simulation of incisions with a biomechanical model of the cornea. METHODS The Cristóbal nomogram was developed based on our experience on the performance of(More)
PURPOSE To investigate the effects of Fuchs' corneal dystrophy (FCD) on corneal biomechanical properties and the results of IOP readings in relation to changes in corneal hysteresis (CH) and central corneal thickness (CCT). METHODS Corneal biomechanical properties, including CH, corneal resistance factor (CRF), and CCT, were measured with the ocular(More)
We report the case of a 13-year-old girl who had fundus flavimaculatus with atrophic macular degeneration. At the age of 14 years, she suffered mild trauma OD, subsequently developing a fibroglial reaction of the retina and pigmentary migration. The coexistence of both phenomena could be explained by the liberation of growth factors by the damaged retinal(More)
We report the case of a 14-year-old girl with multiple findings characteristic of Noonan's syndrome, including short stature, mild mental retardation, facial, skeletal and renal abnormalities. In addition, ophthalmic examination revealed a keratoconus in the left eye and a right optic disc coloboma. To date, only two cases of Noonan's syndrome with(More)
PURPOSE To evaluate the implantation of apodized diffractive multifocal intraocular lenses (IOLs) in children with unilateral cataract. SETTING Ophthalmology Service, Hospital Clínico Lozano Blesa, Zaragoza, Spain. DESIGN Prospective clinical study. METHODS Five children between 4 and 6 years of age with unilateral cataract had cataract extraction and(More)
Wollensak et al. introduced corneal collagen cross-linking (CXL) using riboflavin and ultraviolet-A for the treatment of progressive keratoconus. 1 Empirical in vitro studies evaluated the stiffening effect of CXL and some used human corneas to assess the stiffness achieved, 2,3 but they did not present a histological analysis of the treated human cornea.(More)
CLINICAL CASE A 65-year-old man had been treated with eye-drops containing NSAIDs (Ketorolac). He developed conjunctival injection, edematous swelling of the eyelids and periorbital dermatitis due to a contact allergy. Allergy to NSAIDs is uncommon. DISCUSSION This is an unusual case because topical application of ketorolac is safe in the vast majority of(More)
