BLINK2 Trial Summary

This trial is investigating if soft bifocal contact lenses can help slow myopia progression.

Who is the study for?
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.Check my eligibility
What is being tested?
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.See study design
What are the potential side effects?
While specific side effects are not detailed here, typical concerns with contact lens use include eye discomfort, dry eyes, redness, and potential infection. These aspects may be monitored as part of the study's safety measures.

Experimental Treatment
Group I: Contact lensExperimental Treatment1 Intervention
Depending upon the study lens proven to be the most effective in the BLINK Study, this contact lens will be used for the first two years of the study. The last year of the study, all subjects will be wearing single vision contact lenses.

Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What is the overall objective of this research endeavor?

"The purpose of this three-year investigation is to uncover the statistical link between luminosity and axial length. In addition, we aim to ascertain if there is an "rebound" of myopia after switching from bifocal to single vision contact lenses as well as any changes in accommodative facility or lag over two years with multifocal contact lens wear."

Answered by AI

Can elderly individuals aged 70 or younger join this research trial?

"The requirements for this experiment dictate that prospective participants must be between 10 and 15 years old. 64 people who are under 18 may participate in the trial, as well 16 seniors aged 65 or older."

Answered by AI

Is it possible for me to volunteer in this clinical trial?

"This clinical trial, which is hoping to recruit 248 participants in total, requires individuals with myopia and aged between 10-15 years old."

Answered by AI

Are individuals being recruited to participate in this research currently?

"According to recent clinicaltrials.gov information, this trial is not actively seeking subjects and has been in a static state since May 13th 2022. However, there are still 98 other studies that accept recruits at the moment."
