Cortical dynamics in visual areas induced by the first use of multifocal contact lenses in presbyopes.

A common non-spectacle strategy to correct presbyopia is to provide simultaneous images with multifocal optical designs. Understanding the neuroadaptation mechanisms behind multifocal devices usage would have important clinical implications, such as predicting whether patients will be able to tolerate multifocal optics. The aim of this study was to evaluate the brain correlates during the initial wear of multifocal contact lenses (CLs) using high-density visual evoked potential (VEP) measures.

Translation and validation of convergence insufficiency symptom survey to Italian: Psychometric results.

Purpose: This study aimed to translate the Convergence Insufficiency Symptom Survey (CISS) into the Italian language and assess psychometric properties of the translated questionnaire (CISS_I).

Methods: The CISS_I was arranged according to guidelines for a comprehensive multistep methodologic process for translating, adapting, and validating psychometric instruments in health care research. The CISS_I questionnaire was administered to 103 volunteers (21.

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.

Accuracy, inter-observer and intra-observer reliability in topography assessment of multifocal contact lens centration.

Purpose: To evaluate the accuracy and reliability (inter and intra-observer) of a method to assess multifocal contact lenses (MCLs) centration using a corneal topography unit.

Method: Daily-disposable MCLs (Fusion 1 day Presbyo) were fitted on both eyes of the subjects. For each lens fit a slit lamp digital picture and videokeratograph image were taken in a rapid but randomised sequence.

Refractive error and vision correction in a general sports-playing population.

Purpose: To evaluate, in an amateur sports-playing population, the prevalence of refractive error, the type of vision correction used during sport and attitudes toward different kinds of vision correction used in various types of sports.

Method: A questionnaire was used for people engaging in sport and data was collected from sport centres, gyms and universities that focused on the motor sciences.

Results: One thousand, five hundred and seventy-three questionnaires were collected (mean age 26.
