|
Purpose : To compare the differences in visual quality and accommodative functions after wearing single and multiple front surface aspheric functional contact lenses in the twenties having sufficient accommodation.
Methods : Thirteen subjects(21.38±0.65 years) were evaluated for visual acuity, contrast sensitivity, stray light, total higher order aberrations, spherical aberration, coma aberration, accommodative response, binocular accommodative facility and near point of accommodation after wearing two types of contact lenses, respectively.
Results : There was no significant difference in visual acuity, contrast sensitivity, stray light, total high order aberration, spherical aberration and binocular accommodative facility. Coma aberration increased slightly in wearing multi front aspheric functional contact lenses at 4 and 5 mm pupil size(p=0.037). Accommodative response(p=0.006) and near point of accommodation(p=0.005) were significantly reduced and shorter in wearing multi front aspheric functional contact lens.
Conclusion : There was no difference in visual quality in wearing multiple front aspheric functional contact lenses compared to in wearing single front aspheric contact lenses. But it is thought to be useful as a functional contact lens for young adults because it has the effect on reducing the accommodative burden.
