To evaluate the efficacy of computer based primary Cortex Vision Training (CVT) in improving vision after aspheric monofocal, multifocal and accommodative Intraocular Lens (IOL) implantation.
A prospective, multicenter study investigating efficacy of CVT after implantation of 5 different IOL styles including aspheric monofocal, multifocal and accommodative IOLs in 60 eyes. Uncorrected EDTRS distance visual acuity (UCDVA), near (UCNVA), distance and near contrast sensitivity function (CSF) was tested one month and three months after IOL implantation. Subjects were administered twenty sessions of CVT during the intervening two months. One month and three month data were compared.
Mean age of all subjects was 68 years. After CVT, mean improvement in UCDVA and UCNVA for the entire group was 1.3 and 1.0 lines, and mean improvement in distance and near CSF were 223% and 197% respectively. After CVT, mean improvement in UCDVA and UCNVA for the Crystalens accommodative IOL (N=6) was 0.3 and 1.7, Alcon Restor apodized diffractive IOL (N=10) was 1.5 and 1.1, AMO ReZoom zonal refractive IOL (N=24) was 1.4 and 0.7, Alcon Acrysof aspheric monofocal IOL (N=10) was 1.3 and 0.7, and AMO Technis aspheric monofocal IOL (N=10) was 1.4 and 1.3 lines respectively. Additional refractive and CSF data on each lens group will be reported.
Computer based primary visual cortex training improves uncorrected visual acuity and contrast sensitivity function at both distance and near after aspheric monofocal, multifocal and accommodative intraocular lens implantation.
