Trial Parameters
Brief Summary
The goal of this clinical trial is to learn if daily brief periods of specialized soft contact lens wear work to slow the progression of nearsightedness in children. Additionally, the study will learn about the compliance and safety of specialized soft contact lens wear in children. The main questions it aims to answer are: Does wearing specialized soft contact lenses daily slow myopia progression and axial elongation? What visual/ocular problems do participants have when wearing specialized soft contact lenses? Researchers will compare two soft contact lenses to see if specialized soft contact lens wear works to treat childhood myopia progression. Participants will 1. Wear either a single type of soft contact lens or two types of soft contact lenses at alternate times daily full time in both eyes for one year. 2. Visit the clinic at 2 weeks, 1 month, 3 months, 6 months, and 12 months for checkups and tests 3. Keep a diary of the lens-wearing times.
