Resumo: Purpose: The purpose of this study was to show the potential of a commercial center-distance multifocal soft contact lens to induce relative peripheral myopic defocus in myopic eyes. Methods: Twenty-eight myopic right eyes from 28 patients (mean age: 22.0 ± 2.0 years) were evaluated. The measurements of axial and off-axis refraction were made using a Grand-Seiko WAM-5500 open-field autorefractometer without lens and with multifocal contact lenses (Proclear Multifocal D® Design) of +2.00 D and +3.00 D add power applied randomly. Central mean spherical equivalent refraction was −2.24 ± 1.33 D. Ocular refraction was measured at center and at eccentricities between 35◦ nasal and 35◦ temporal (in 5◦ steps). Results: Baseline relative peripheral refractive error (RPRE) as spherical equivalent (M) was −0.69 ± 1.14 D and −0.46 ± 1.38 D at 35◦ in the nasal and temporal degrees of visual field, respectively. Both add powers increased the relative peripheral myopic defocus up to −0.82 ± 1.23 D (p = 0.002) and −1.42 ± 1.45 D (p < 0.001) at 35◦ in the nasal field; and −0.87 ± 1.42 D (p = 0.003) and −2.00 ± 1.48 D (p < 0.001) at 35◦ in the temporal retina with +2.00 D and +3.00 D add lenses, respectively. Differences between +2.00 and +3.00 D add lenses were statistically significant beyond 20◦ in the nasal visual field and 10◦ in the temporal visual field. Conclusion: It is possible to induce significant changes in the pattern of relative peripheral refraction in the myopic direction with commercially available dominant design multifocal contact lenses. The higher add (+3.00 D) induced an significantly higher effect than the +2.00 D add lens, although an increase of 1 D in add power does not correspond to the same amount of increase in RPRE.

Métodos: Se evaluaron veintiocho ojos derechos miopes pertenecientes a 28 pacientes (edad media: 22,0 ± 2,0 anos). ˜ Las mediciones de la refracción axial y fuera del eje se realizaron utilizando un autorrefractómetro de campo abierto Grand-Seiko WAM-5500 sin lentes, y con lentes de contacto multifocales (Diseno˜ Proclear Multifocal D®) de adición de potencia de +2,00D y +3,00D, aplicadas de manera aleatoria. La refracción equivalente esférica media y central fue de -2,24 ± 1,33D. La refracción ocular se midió en el centro, y a excentricidades comprendidas entre 35◦ nasales y 35◦ temporales (en pasos de 5◦). Resultados: El error refractivo periférico relativo basal (RPRE), como equivalente esférico (M), fue de -0,69 ± 1,14D y -0,46 ± 1,38D a 35◦ en las regiones nasal y temporal del campo visual, respectivamente. Ambas adiciones de potencias incrementaron el desenfoque miópico periférico relativo hasta -0,82 ± 1,23D (p = 0,002) y -1,42 ± 1,45D (p < 0,001) a 35◦ en el campo nasal, y -0,87 ± 1,42D (p = 0,003) y -2,00 ± 1,48D (p < 0,001) a 35◦ en el campo retiniano temporal con lentes de adición de +2,00D y +3,00D, respectivamente. Las diferencias entre las lentes de adición de +2,00 y +3,00D fueron estadísticamente significativas para excentricidades superiores a 20◦ en el campo visual nasal, y superiores a 10◦ en el campo visual temporal. Conclusión: Es posible inducir cambios miópicos significativos en el patrón de la refracción periférica relativa en la con las lentes de contacto multifocales de diseno˜ dominante, comercialmente disponibles. La adición mayor (+3,00D) indujo un efecto significativamente mayor que las lentes de adición de +2,00D, aunque el incremento de 1D en la adición de potencia no se corresponde con la misma cantidad de incremento en términos de cambio en el error refractivo periférico relativo.FCT -Fuel Cell Technologies Program(PTDC/SAU-BEB/098392/2008)Elsevier DoymaUniversidade do MinhoFerreira, Daniela LopesRibeiro, C.Neves, HelenaRibeiro, Miguel António FariaQueirós, A.Villa-Collar, CésarJorge, JorgeGonzález-Méijome, José Manuel20132013-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttps://hdl.handle.net/1822/37174engLopes-Ferreira, D.P.; Ribeiro, C.; Neves, H.I.F.; Faria-Ribeiro, M.; Queirós, A.; Villa-Collar, C.; Jorge, J.M.M.; González-Méijome, J.M.Peripheral refraction with dominant design multifocal contact lenses in young myopes, Journal of Optometry, 6, 2, 85-94, 2013.1888-429610.1016/j.optom.2013.01.001info:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-10-14T01:18:36Zoai:repositorium.sdum.uminho.pt:1822/37174Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T18:57:16.863408Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
