To analyze the prevalence and presentation patterns of corneal astigmatism in cataract surgery candidates.University Valencia, Spain.Refractive keratometric values were measured before patients having extraction. Descriptive statistics refractive cylinder data analyzed correlated by age ranges.Refractive from 4,540 eyes 2,415 (mean 60.59 years +/- 9.87 [SD]; range 32 to 87 years) differed significantly when divided into 10-year subsets. There was a trend toward less negative values, except...

The purpose of this study was to characterize the central and peripheral refraction across horizontal meridian visual field before after myopic corneal refractive therapy (CRT) with contact lenses.Twenty-eight right eyes from 28 subjects (mean age +/- SD = 24.6 6.3 years) were fitted Paragon CRT lenses treat myopia between -0.88 -5.25 D spherical equivalent. Along a complete set examination procedures assess suitability for treatment, refractions measured along up 35 degrees eccentricity in...
To evaluate the long-term safety and efficacy of posterior chamber collagen copolymer phakic intraocular lens (pIOL) implantation to correct myopia.Fernández-Vega Ophthalmological Institute, Oviedo, Spain.Cohort study.Uncorrected (UDVA) corrected (CDVA) distance visual acuities, refraction, pIOL vault, endothelial cell loss, adverse events were evaluated for 5 years after Visian Implantable Collamer Lens moderate high myopia.The mean spherical equivalent (188 eyes) decreased from -11.17...
Objective. To evaluate the degree of axial elongation with soft radial refractive gradient (SRRG) contact lenses, orthokeratology (OK), and single vision (SV) spectacle lenses (control) during a period 1 year before treatment 2 years after treatment. Methods. This was prospective, longitudinal, nonrandomized study. The study groups consisted 30, 29, 41 children, respectively. length (AL) measured recruitment lens fitting. Results. baseline sphere correlated significantly (Spearman’s Rho ( ρ...
Purpose. To compare the through-focus visual performance in a clinical population of pseudophakic patients implanted with two new trifocal intraocular lenses (IOLs) and one extended depth focus IOL. Methods. Prospective, nonrandomized, examiner-masked case series. Twenty-three received FineVision® seven PanOptix™ IOLs. Fifteen Symfony Mean age was 63 ± 8 years. Through-focus acuity measured from –3.00 to +1.00 D vergences. Contrast sensitivity without source glare. Light disturbances were...
We defined the theoretical oxygen tension behind modern scleral contact lenses (CLs) made of different rigid gas permeable (RGP) materials, assuming thickness tear layer lens. A second goal was to show clinically effect postlens film on corneal swelling.We simulated partial pressure across cornea CLs lens materials (oxygen permeability Dk, 75-200 barrer) and (Tav, 100-300 μm). Postlens thicknesses (Tpost-tear) ranging from 150 350 μm were considered. Eight healthy subjects fitted randomly...
Abstract The aim of this study was to evaluate the accuracy measurement intraocular pressure (IOP) using a new induction/impact rebound tonometer (ICare®) in comparison with Goldmann applanation (AT). left eyes 46 university students were assessed two tonometers, induction tonometry being performed first. ICare® handled by an optometrist and ophthalmologist. In study, statistically significant differences found when comparing (AT) ( p < 0.05). mean difference between tonometers 1.34 ±...
To compare thickness measurements of the central 6.0 mm cornea obtained with Orbscan(R) II topography system and topographical ultrasound pachymetry.School Optometry, University Santiago de Compostela, Galicia, Spain.In 24 right eyes, pachymetric were taken at center 1.2 3.0 on superior inferior hemimeridians. A 1-sample t test was applied to assess significance relationship between Orbscan methods. The 2 assessed by analyzing regression plotting differences against mean corneal thickness....
To evaluate the changes in correlations of higher order aberrations first corneal surface with halo phenomena, a form image degradation, under night vision conditions measured objectively after successful LASIK (laser situ keratomileusis) surgery.A prospective, observational, analytical study 110 eyes that had undergone surgery for myopia and astigmatism. Preoperative sphere was (mean (SD)) -3.48 (1.70) D (0 to -8.00 D) preoperative cylinder -0.86 (0.87) -4.00 D). Visual disturbance caused...
PURPOSE: To assess the safety, efficacy, stability, and predictability of collagen copolymer toric phakic intraocular lens (pIOL) implantation to correct myopia astigmatism in eyes with keratoconus. SETTING: Fernández-Vega Ophthalmological Institute, Oviedo, Spain. METHODS: This prospective study comprised keratoconic that had a Intraocular Collamer Lens. Uncorrected (UDVA) corrected (CDVA) distance visual acuities, refraction, postoperative complications were evaluated 1, 3, 6, 12 months...
PURPOSE: To evaluate the changes in corneal transparency and thickness measured objectively using Pentacam Scheimpflug (Oculus Optikgeräte GmbH) tomography (densitometry) after cross-linking (CXL). METHODS: Twenty-two eyes from 15 patients with keratoconus underwent CXL. Corneal curvature as well lens densitometry were at baseline 1, 3, 6, 12 months CXL Pentacam. RESULTS: Immediately CXL, central significantly decreased (−40 μ m) increased significantly. At 6-month follow-up, values reduced...
To compare visual performance with the Biofinity multifocal (MF) contact lens monovision (MV) single-vision lens.A crossover study of 20 presbyopic patients was conducted. Patients were randomized first into either an MF or MV for 15 days each modality, a washout period between type. Measurements included monocular and binocular high- low-contrast logarithm minimum angle resolution acuity (VA) at distance near visions, contrast sensitivity function, stereoacuity.At days, lost fewer than two...
Purpose. The ICare (Tiolat Oy, Helsinki, Finland) is a new portable tonometer that measures intraocular pressure (IOP) with rebound method, in which very light probe used to make momentary contact the cornea slow motion. purpose of this study assess accuracy IOP measurements by comparing them against other tonometers: Perkins applanation and Tono-Pen XL digital (Medtronic Solan, Jacksonville, FL). Methods. Sixty-five young subjects were assessed each tonometers. tonometry was performed...
