Data from a clinical study exploring the extended depth of focus (EDOF) design of Visioneering Technologies Inc’s NaturalVue Enhanced Multifocal 1 Day contact lens has been published in Clinical Ophthalmology.
VTI said the study represented its highest evidence of presbyopia visual function, patient satisfaction and supported its universal ADD claim for presbyopia.
It analysed the range of functional vision and subjective feedback on patients aged 50 years and older living with presbyopia. Patients demonstrated improvement in visual acuity with NaturalVue Multifocal versus single vision correction from -1.50D through -4.00D optical vergence demand, simulating reading material from 66cm to 25cm.
Results found the multifocal provided a wide range of visual function with better than 6/12 binocular vision up to a reading distance of approximately 28cm while preserving spectacle-level distant vision and stereopsis. It also concluded that NaturalVue Multifocal provided the same level of vision and satisfaction for mild and intermediate presbyopes.
