What You Need to Know Before You Apply

What is the purpose of this trial?

This project intends to provide important, previously unmet answers regarding biological associations with myopia (nearsightedness) progression in order to improve the ability to predict patients who are most likely to benefit from myopia control, as well as questions frequently posed by patients and practitioners about the side effects, mechanism, and discontinuation of soft bifocal contact lens myopia control. The first three aims examine the association between biological variables that can be measured non-invasively and myopia progression, and they will be conducted regardless of the outcome of the currently in progress BLINK Study. The last three specific aims will be conducted if soft bifocal contact lenses slowed myopia progression by 30% or more in the BLINK Study, and they can be investigated with very few additional measurements.

Are You a Good Fit for This Trial?

This trial is for individuals who were part of the BLINK Study, focusing on those with near-sightedness (myopia). It aims to identify biological factors that could predict which patients will benefit most from myopia control using soft bifocal contact lenses.

What Are the Treatments Tested in This Trial?

Interventions

  • Soft Bifocal Contact Lens
Trial Overview The study tests if wearing soft bifocal contact lenses can slow down the worsening of near-sightedness. The research hinges on earlier findings; if prior results show a 30% improvement, this trial will explore additional benefits and mechanisms.
