Overview
The goal of this clinical trial is to study changes in eye shape of nearsighted young adults using low-dose atropine eye drops or soft multifocal contact lenses. The main questions it aims to answer are:
- do low-dose atropine and soft multifocal contact lenses affect the shape of the peripheral eye?
- are changes in peripheral eye shape from these interventions influenced by changes in the focusing system of the eye?
Participants will:
- have multiple different types of photos taken
- have their prescription for glasses/contacts checked
- have their eye health checked, including the use of dilating eye drops
- be randomly assigned to use eye drops every night or wear special contact lenses daily instead of their typical contacts
- will complete five study visits over the course of 12 months
Researchers will compare young adults using low-dose atropine to those wearing soft multifocal contact lenses and to those using no intervention to see if using these interventions affects retinal shape.
