PURPOSE To compare the discriminating ability of corneal elevation generated by a dual Scheimpflug analyzer calculated with different reference surfaces for distinguishing normal corneas from those with keratoconus and subclinical keratoconus. METHODS A total of 391 eyes of 208 patients were prospectively enrolled in the study and divided into three(More)
PURPOSE To analyze the induced corneal higher order aberrations (HOAs) after wavefront-optimized ablation. METHODS Sixty-four myopic eyes that underwent wavefront-optimized myopic LASIK were divided into three groups based on spherical equivalent (SE): low myopia group (23 eyes with SE <-3.00 diopters [D]); moderate myopia group (27 eyes with SE between(More)
PURPOSE To develop a method for automatizing the detection of subclinical keratoconus based on a tree classification. DESIGN Retrospective case-control study. METHODS setting: University Hospital of Bordeaux. participants: A total of 372 eyes of 197 patients were enrolled: 177 normal eyes of 95 subjects, 47 eyes of 47 patients with forme fruste(More)
PURPOSE To evaluate the use of subconjunctival bevacizumab on corneal neovascularization in an experimental rabbit model for its effect on vessel extension, inflammation, and corneal epithelialization. METHODS In this prospective, randomized, blinded, experimental study, 20 rabbits were submitted to a chemical trauma with sodium hydroxide and subsequently(More)
PURPOSE To evaluate changes in corneal sensitivity after corneal collagen crosslinking in patients having progressive keratoconus. METHODS Thirty-six consecutive patients having progressive keratoconus were included in the study. The crosslinking surgery was performed in one eye of each patient (study group) and the opposite eye was used as control(More)
This review of wavefront technology looks at 2 major aspects. The first is the basics and principles of the optics of the eye, how to decompose the wavefront in a more adequate way for interpretation, and how these aberrations affect the visual acuity. It also addresses the diversity and complexity of wavefront sensors; how these devices transform the(More)
PURPOSE To determine whether the improvement in intermediate vision after bilateral implantation of an aspheric multifocal intraocular lens (IOL) with a +3.00 diopter (D) addition (add) occurs at the expense of optical quality compared with the previous model with a +4.00 D add. SETTING Department of Ophthalmology, University of São Paulo, São Paulo,(More)
PURPOSE To investigate the association of a novel metric, percent tissue altered, with the occurrence of ectasia after laser in situ keratomileusis (LASIK) in eyes with normal corneal topography and to compare this metric with other recognized risk factors. DESIGN Retrospective case-control study. METHODS The study included 30 eyes from 16 patients with(More)
PURPOSE To evaluate retrospectively the outcomes of a case series of deep anterior lamellar keratoplasties by air dissection (DALK-AD) using the big bubble (BB) technique, in the surgical treatment of keratoconus (KC). METHODS Forty-four consecutive keratoplasties of 42 patients for KC were performed at the French National Reference Center for KC from(More)
PURPOSE To compare the changes in corneal power (ΔK) induced by myopic ablations estimated by Placido-disk and total corneal power (TCP) ray tracing methods to the refractive change (ΔSE). METHODS Manifest refraction, simulated keratometry from a Placido-disk based system, and TCP from a dual-Scheimpflug analyzer were obtained from 35 patients (58 eyes)(More)
