Effect of Biofeedback Training on Accommodation During Multifocal Lens Wear in Young Adults

Description

This study will examine the accommodative behavior in young adults wearing multifocal soft contact lenses. undergoing myopia control treatments. Subjects will undergo auditory biofeedback training while wearing the multifocal contact lenses to improve the accommodative. This pilot study is divided into three separate experiments and aims to assess: 1. the time course of the effect of biofeedback training in young adults wearing MFCLs -- the time course group 2. whether repeated biofeedback training increases the efficacy in young adults wearing MFCLs -- the repetition group 3. whether a longer training duration, given repeatedly, increases the efficacy in young adults wearing MFCLs -- the longer duration group The results of this study will be used to design a larger clinical trial to investigate whether increasing accommodative responses through the multifocal contact lenses increases multifocal lenses' treatment effect on myopia management in children.
