Accommodation, Myopia
Conditions
Brief summary
The purpose of this study is to report the changes in accommodation, aberrations, and myopia in patients wearing multifocal soft contact lens for various durations. The study objectives are to: 1. Determine the effects of wearing multifocal soft contact lens on accommodation and aberrations over a 12-month period. 2. Determine the effect of wearing multifocal soft contact lens on myopia over a 12-month period.
Interventions
