Centration assessment of an extended depth of focus contact lens for myopic progression control.

Purpose: To evaluate the accuracy and the inter and intra-observer reliability of the centration assessment of extended depth of focus (EDOF) contact lenses (CL) using corneal topography.

Method: EDOF soft CLs (Mylo, Mark'Ennovy) were fitted on thirty-three myopic students (25 females), aged 19-28 years (22.7 ± 2.

Computerised dynamic posturography for postural control assessment in subjects wearing multifocal contact lenses dedicated for myopia control.

Purpose: To measure body balance using computerised dynamic posturography in young adults wearing multifocal contact lenses (MFCL) with high addition powers designed for myopia control.

Methods: Twenty-four young adults (mean age: 24 years) wearing distance-centred soft MFCL (SwissLens Orbis Relax) with two different central zones (3 and 4.5 mm), two addition powers (+2 D, +4 D) and single vision control lenses.

Contrast sensitivity and visual acuity in subjects wearing multifocal contact lenses with high additions designed for myopia progression control.

Objectives: To assess the visual performance of multifocal contact lenses (MFCLs) with high addition powers designed for myopia control.

Methods: Twenty-four non-presbyopic adults (mean age 24 years, range 18-36 years) were fitted with soft MFCLs with add powers of +2.0 D (Add2) and +4.
