Visual Function after Implantation of a Presbyopia-Correcting Trifocal Intraocular Lens
2019
<b><i>Purpose:</i></b> To evaluate distance, intermediate, and near visual performance in patients implanted with a trifocal aspheric presbyopia-correcting intraocular lens (IOL). <b><i>Methods:</i></b> Forty patients were bilaterally implanted with the AcrySofIQ PanOptix IOL after femtosecond laser-assisted lens surgery. Binocular best corrected distance visual acuity (CDVA) (4 m), best distance-corrected near visual acuity (DCNVA) (40 and 30 cm), best corrected distance intermediate visual acuity (DCIVA) (70, 60, and 50 cm), binocular distance contrast sensitivity under photopic conditions (85 cd/m<sup>2</sup>), and defocus curve…
The combination of diffractive and refractive multifocal intraocular lenses to provide full visual function after cataract surgery.
2009
PURPOSE To investigate if implantation of a far dominant refractive multifocal intraocular lens (IOL) in one eye and a near dominant diffractive multifocal IOL in the fellow eye improves range of vision following cataract surgery. METHODS This was a prospective, nonrandomized, case-control study involving 20 patients (40 eyes) scheduled for cataract surgery. Inclusion criteria were bilateral cataracts, minimum age 50 years, availability for follow-up visits, and informed consent. All patients received a far dominant refractive multifocal IOL (ReZoom, Abbott Medical Optics) in their dominant eye and a near dominant diffractive multifocal IOL (Tecnis ZM900, AMO) in their nondominant eye. Preo…
Stereoacuity After Refractive Lens Exchange With AcrySof ReSTOR Intraocular Lens Implantation
2009
Purpose: To evaluate stereoacuity before and after refractive lens exchange (RLE) with AcrySof ReSTOR intraocular lens (IOL) implantation. Methods: Stereoacuity was measured using the Titmus stereotest at 40 cm under photopic conditions (85 cd/m 2 ) before and after RLE with bilateral AcrySof ReSTOR Natural (SN60D3 model) implantation in 30 hyperopic eyes of presbyopes with low astigmatism (⩽1.00 diopter [D]). Stereoacuity measurements after implantation were compared with those found before surgery. Results: Stereoacuity was unchanged after RLE with pseudoaccommodative IOL implantation. In this population of non-cataractous hyperopes with excellent preoperative stereoacuity (46.42±1.36 se…
Technical Report: Repeatability of Contrast Sensitivity Test in Children
2020
Contrast sensitivity (CS) in children is not routinely measured in the clinical setting, although CS losses have been found in amblyopic and premature children. Thus simple visual acuity measurements do not completely assess their quality of vision. To evaluate contrast sensitivity in children, a reliable and easy test, sampling the entire spatial frequency range, is necessary. Purpose This study aimed to evaluate the repeatability and normal range of the contrast sensitivity function measured using the Topcon CC-100 instrument, in children aged between 4 and 9 years, for use as a diagnostic tool. Methods Contrast sensitivity was measured in 25 children, 11 boys and 14 girls, with normal or…
Psychomotor, Psychosocial and Reading Skills in Children with Amblyopia and the Effect of Different Treatments
2020
Amblyopia influences psychomotor and psychosocial skills, although not all studies are unanimous. Different treatments coexist, but the effect on those variables is not clear. This study aims to probe whether children with amblyopia have impairments in these areas and if different optometric treatments reduce them effectively. 50 children, diagnosed with amblyopia, and 33 without amblyopia participated in this study. Eye-hand coordination, psychosocial skills and reading abilities, were measured before and after three months of different treatments (patch, patch and near vision activities and perceptual learning). Results revealed lower scores in eye-hand coordination and some reading issue…
Visual function after implantation of an aspheric bifocal intraocular lens.
2009
Purpose To evaluate distance, intermediate, and near vision after bifocal aspheric AcrySof ReSTOR SN6AD1 intraocular lens (IOL) implantation. Setting Fernandez-Vega Ophthalmological Institute, Oviedo, Spain. Methods Binocular distance best corrected visual acuity (BCVA) (4.0 m), best distance-corrected near (40.0 cm) and intermediate (70.0, 60.0, 50.0 cm) acuities, and contrast sensitivity under photopic (85.0 candelas [cd]/m 2 ) and mesopic (3.0 cd/m 2 ) conditions with and without glare were measured postoperatively. A patient-satisfaction and visual phenomena questionnaire was administered. Results Six months postoperatively, the mean acuities (logMAR) were binocular BCVA, −0.064 ± 0.049…
Visual function after bilateral implantation of a new zonal refractive aspheric multifocal intraocular lens.
2011
Purpose To evaluate visual function after bilateral implantation of a zonal refractive aspheric multifocal intraocular lens (IOL). Setting Private practice surgery center, Valencia, Spain. Design Cohort study. Methods Consecutive eyes with cataract had bilateral implantation of Lentis Mplus LS-312 multifocal IOLs. Distance, intermediate, and near visual acuities; contrast sensitivity; defocus curves; and a quality-of-vision questionnaire, including presence of halos or dysphotopsia, were evaluated 6 months postoperatively. A control group of age-matched monofocal pseudophakic patients was included to compare contrast sensitivity function. Results In the multifocal group, the mean binocular …
Multifocal intraocular lenses for unilateral cataract in children.
2009
Purpose To evaluate the implantation of apodized diffractive multifocal intraocular lenses (IOLs) in children with unilateral cataract. Setting Ophthalmology Service, Hospital Clinico 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 implantation of an apodized diffractive multifocal IOL (AcrySof Restor SN60D3). Phacoaspiration was accompanied by posterior capsulorhexis followed by an anterior vitrectomy. Uncorrected distance (UDVA), corrected distance (CDVA), and corrected near (CNVA) visual acuities; binocular function using the Worth 4-dot test and the TNO stereotest; a…
Can the grey mould disease of the grape-vine be controlled by yeast?
2000
Botrytis cinerea has been found to be highly pathogenic to ‘Chardonnay’ and ‘Pinot noir’ cultivars of the grape-vine producing the characteristic grey mould symptoms within 7 days of inoculation to the vitro-plants. The yeast Pichia anomala (strain FY-102), isolated from apple skin, was found to be antagonistic to B. cinerea as it completely inhibited the appearance of the grey mould symptoms when grown together. The yeast was responsible for morphological changes such as coagulation and leakage of the cytoplasm of B. cinerea. The pathogen, when applied together with P. anomala, failed to bring about the grey mould symptoms on the grape-vine, suggesting that the yeast could control the expr…
Countering accusations with inoculation: The moderating role of consumer-company identification.
2013
Abstract Accusations of wrongdoing, baseless or justified, can severely tarnish a company's reputation. Once disseminated, even baseless accusations can persist and cause considerable damage for a company. This study examines the proactive crisis communication strategy of inoculating individuals against invalid accusations before they go viral. An experiment was conducted in a real world consumer context among members of an online consumer panel using an electronics discounter as the research stimulus. Expanding previous inoculation research on the role of value-relevant involvement for inoculation and the effectiveness of inoculation in the case of different preexisting attitudes, we find …
