Calidad visual en pacientes con lente intraocular multifocal modelo OcuFlex operados de catarata The quality of vision in patients operated on from cataract and implanted with OcuFlex multifocal intraocular lenses.
La totalidad de los pacientes se manifestaron satisfechos. METHODS: A prospective, longitudinal, observational and descriptive study was made in which the variables spheral equivalent, contrast sensitivity in the pre- and post. This paper described the results of the intraocular lens implantation performed in children, who had been seen at the Pediatric Ophthalmologic Service of " Ramon Pando Ferrer " Cuban Institute of Ophthalmology and had been diagnosed as having cataract of various etiologies, from April to April They were all followed-up for a year.
The dioptric power of the most common intraocular lens and the most frequent complications during and after surgery were identified. The patients requiring additional treatment such as laser capsulotomy and surgical.
Lente intra-ocular multifocal difrativa apodizada: resultados Diffractive apodized multifocal intraocular lens: results. Binocular visual acuity was evaluated with and without correction for near and distance, and refraction previsibility and frequency of wearing glasses. Resultados da troca de lente intra-ocular de hidrogel opacificada.
El procedimiento comprende las etapas de: 1. El manejo de esta entidad debe ser personalizado. A case of dislocated intraocular lens moved to the vitreous cavity in a patient with low endothelial cell count and contact lens intolerance was reported. A pars plana vitrectomy with lens repositioning was performed to demonstrate the safety of this technique for some special cases under adequate conditions.
The literature was reviewed to learn about the current management of this pathology. The stability of the lens was confirmed three month l after the vitrectomy. Management of this disorder should be customized. This technique should be considered as the first option of treatment and seems to be safe in selected cases. Los pacientes fueron distribuidos en dos grupos 82 pacientes en cada grupo por sorteo de forma aleatoria, con y sin fentanil.
A cirurgia da catarata tem vindo a evoluir ao longo dos anos, tendo sido realizado o primeiro implante de uma lente intra-ocular em Other diseases affecting the vision were excluded. The preoperative. Gravitational lensing is a fundamental tool for cosmology. A recent instrument which will provide more information for models of these objects is ALMA.
We had selected 12 quadruple images systems from the CASTLES database, which show a high probability of observing extended sources in the submillimetric range. These new data will allow us to improve existing models. Las lentes gravitatorias Estas constantes personalizadas para cada cirujano no mostraron diferencias significativas. Method: a retrospective and descriptive study was made to study the A constant.
OBJECTIVE: To determine the correlation between the location of the intraocular lens in the posterior chamber using ultrasonic biomicroscopy and the different surgical parameters in patients operated from cataract. Intractable diplopia has been described in many situations but poor results are the rule with standard treatment modalities. The authors report a case of a woman with long-standing strabismus and diplopia who failed to improve following surgery, prism, and occlusive spectacles or contact lenses.
Then, she was submitted to phacoemulsification and opaque intraocular lens implantation, which successfully neutralized diplopia.
Todos os ensaios foram executados em duplicata. Lentes plegables suturadas a iris. Acuidade visual em implantes bilaterais de lentes intra-oculares monofocais e multifocais Visual acuity of bilateral implants of monofocal and multifocal intraocular lenses.
PURPOSE: To compare distant and near visual acuity between patients submitted to bilateral nonsimultaneous facoemulsification and implantation of multifocal or monofocal intraocular lenses IOL. Todas as cepas produziram biofilme. PURPOSE: To evaluate bacterial adherence to silicone and polymetylmethacrylate PMMA intraocular lenses as a risk factor for postsurgery endophthalmitis by using an in vitro model with three potentially pathogenic microorganisms.
Efectividad de la lente intraocular ACRI. Nenhum paciente relatou halos ou 'glare' severos, sendo os mesmos caracterizados entre nenhum a moderado. A patient-satisfaction and visual phenomena questionnaire was administered at the end of the study. METHODS: This prospective randomized bilateral double-masked clinical study included 52 patients with visually significant bilateral cataracts divided in two groups; 25 patients 50 eyes received aspherical intraocular lens in one eye and spherical intraocular lens in the fellow eye; and 27 patients 54 eyes received ultraviolet and blue light filter yellow tinted IOL implantation in one eye and acrylic ultraviolet filter IOL in the fellow eye.
The primary outcome measures were contrast sensitivity and blue-on-yellow perimetry values mean deviation [MD] and pattern standard deviation [PSD] investigated two years after surgery. The results were compared intra-individually. RESULTS: There was a statistically significant between-group aspherical and spherical intraocular lens difference in contrast sensitivity under photopic conditions at 12 cycles per degree and under mesopic conditions at all spatial frequencies.
There were no between-group significant differences yellow tinted and clear intraocular lens under photopic or mesopic conditions. Blue-on-yellow perimetry did not appear to be affected by aspherical or yellow tinted intraocular lens. Further studies with a larger sample should be carried out to confirm or not that hypotheses. A idade variou entre 7 e 22 anos. Em todos os casos observou-se um adequado posicionamento do anel e um bom suporte capsular.
PURPOSE: To evaluate the contrast sensitivity and stereopsis tests in patients who underwent bilateral implantation of multifocal intraocular lens. Postoperative Snellen visual acuity and intraocular pressure IOP, and early and late complications were assessed. Participaram do estudo 43 olhos de 40 pacientes. At least And The mean spherical error was 0.
However, contrast sensitivity was lower in the multifocal group. Se describe una manera sencilla de construirlo con materiales comunes. It is estimated that around 1,5 million children with low vision or legally blind exist worldwide, with a prevalence of 1 to 4 per 10 children in the industrialized countries and of 5 to 15 in the developing countries.
The prevalence of blindness due to. The authors report a case of congenital cataract, which was treated with piggyback foldable intraocular lens implant, not described in the Brazilian literature. The differences and similarities are analyzed with other reported cases in the literature. Las lentes de hidrogel de silicona son las que se asocian a mayor confort.
PURPOSE: To evaluate the visual function and satisfaction of patients who underwent cataract surgery and were implanted with an accommodative intraocular lens and the impact in their quality of life. PURPOSE: To evaluate prospectively the results of expandable acrylic intraocular lenses in patients submitted to phacoemulsification as regard posterior capsule opacification.
METHODS: The study group consisted of patients, 1, eyes that underwent phacoemulsification from to , by the same surgeon, using the same technique but with different diameters of capsulorrhexis, with expandable hydrophilic acrylic intraocular lens implantation.
The mean follow-up was 2. Acanthamoeba sp. Full Text Available La queratitis por Acanthamoeba sp. Clinically, it can be mistaken for a herpes infection. One of the few registered cases of Acanthamoeba sp. PURPOSE: Compare the wavefront and contrast sensitivity of bilateral pseudophakic patients with aspheric in one eye and spheric intraocular lenses in the other. Twenty males and females non-diabetic dogs of different breeds and ages underwent ophthalmic examination because they presented catarats.
The obtained mean axial length was All animals were submitted to extracapsular phacoemulsification; the mean intraocular lens power implanted was At 60 days postoperative, the refractional error assessed via retinoscopy was 5.
Patients were subject to frequency doubling technology Matrix Perimeter testing. The mean pupillary diameter under scotopic conditions was 6. The mean deviation was The pattern standard deviation was 3.
The mean age was 8. Patients underwent phacoaspiration, endocapsular ring and intraocular lens IOL implantation. The implanted IOL had one loop haptic excised and was supported above the ring, inside the capsular bag promoting intraocular lens centralization. METHODS: This retrospective study included 37 patients' eyes divided into 2 groups: extracapsular cataract extraction, posterior chamber intraocular lens implantation and penetrating keratoplasty Group 1, G1 and transscleral fixation of posterior chamber lens and penetrating keratoplasty Group 2, G2.
The following parameters were recorded: visual acuity, intraocular pressure, refractive astigmatism, complication and keratometric astigmatism.
Regarding refractive and keratometric astigmatism no significant differences between the groups were found. The follow-up was 11 months. Aleatoriamente, os pacientes foram divididos em dois grupos. Purpose: Cataract is the main cause of blindness throughout the world, affecting more than 15 million people worldwide. There are different techniques for extracapsular cataract. Lentes de contacto.
