Sorpresa refractiva tras la cirugía de catarata en paciente con lente fáquica
Refractive surprise after cataract surgery in a patient with a phakic lens implant

Rev. cuba. oftalmol; 34 (3), 2021
El implante de una lente intraocular fáquica puede resultar una opción lógica para los pacientes sumamente miopes que buscan liberarse de las gafas y de los lentes de contacto. Esta es una alternativa para corregir los grados de miopía extremos, y se diseñaron para permanecer dentro del ojo por much...

Influência da orientação das ranhuras superficiais na flexão rotativa de fios de níquel-titânio
Influence of surface grooves orientation on the cyclic fatigue resistance of NiTi wire

Dent. press endod; 11 (1), 2021
Objetivo: Testar a hipótese nula de que a orientação das ranhuras superficiais não influencia na vida em fadiga de fios de níquel-titânio (NiTi). Material e Métodos: Segmentos de fio de NiTi (Moreli, Sorocaba/SP, Brasil) medindo 30mm e com diâmetro de 0,40mm foram utilizados. As ranhuras foram cr...

Analise dos dados biométricos gerados por interferometria comparada com Scheimpflug

Rev. bras. oftalmol; 79 (5), 2020
Resumo Objetivo: Observar o grau de concordância das variáveis analisadas entre os dispositivos IOL Master 500 e Pentacam AXL e descrever as medias Métodos: Foram analisados 35 prontuários, totalizando 61 olhos. Todos os pacientes se submeteram à avaliação biométrica nos dois dispositivos, no ...

Cirugía de catarata bilateral en paciente con lente intraocular fáquica
Bilateral cataract surgery in a patient with a phakic intraocular lens

Rev. cuba. oftalmol; 33 (3), 2020
RESUMEN La cirugía refractiva corneal es una buena opción para corregir el defecto refractivo de los pacientes y lograr una buena visión sin el uso de espejuelos o lentes de contacto; pero cuando no es posible, las lentes fáquicas constituyen una elección viable, especialmente en pacientes jóvenes ...

Comparing the postoperative refractive predictability of Pentacam HR and IOLMaster 500 after a multifocal intraocular lens implantation

Arq. bras. oftalmol; 83 (2), 2020
ABSTRACT Purpose: To compare the postoperative refractive predictability of IOLMaster 500 and Pentacam HR on the basis of keratometry and anterior chamber depth values in eyes with an indication for multifocal intraocular lens (IOL) implantation. Methods: This was a retrospective study conducted on 118...

Evolución de la biometría de coherencia óptica y las nuevas plataformas
Evolution of optical coherence biometry and the new platforms

Rev. cuba. oftalmol; 32 (2), 2019
RESUMEN La interferometría de coherencia óptica es un procedimiento esencial para calcular la potencia óptica de la lente intraocular. La presente revisión describe la evolución de la biometría óptica por interferometría, las nuevas plataformas, las características técnicas, los parámetros de ...

Corneal Astigmatism in cataract surgery candidates

Rev. bras. oftalmol; 77 (5), 2018
Abstract Purpose: To report the prevalence and analyse corneal astigmatism patterns in cataract surgery candidates. Methods: Researchers examined 2136 eyes from 1204 patients for cataract surgery from 1 January to 31 December 2016. All the candidates were evaluated with partial coherence interferometry...

Long-term microwaving of denture base materials: effects on dimensional, color and translucency stability

J. appl. oral sci; 26 (), 2018
Abstract While the combined effect of microwave irradiation with cleansing solutions on denture base materials has been investigated, the effects of only using microwave irradiation and, more importantly, in a long-term basis, was not studied yet. Objective The purpose of this study was to evaluate the...

Noncontact three-dimensional evaluation of surface alterations and wear in NiTi endodontic instruments

Abstract The aim of this study was to undertake a qualitative and quantitative assessment of nanoscale alterations and wear on the surfaces of nickel-titanium (NiTi) endodontic instruments, before and after use, through a high-resolution, noncontact, three-dimensional optical profiler, and to verify the ...
