BLINK will investigate optical ramifications of soft multifocals on myopia control

Currently ongoing, the Bifocal Lenses In Nearsighted Kids study is a 3-year, NIH-sponsored, double-masked, randomized clinical trial to determine whether soft multifocal contact lenses slow myopia progression.
If proven successful, BLINK will provide information on how soft multifocal contact lenses can be optimized for myopia control, according to researchers.
A total of 294 subjects between 7 to 11 years old have been enrolled in the study, with -0.75 D to -5.00 D spherical component and <1.00 D astigmatism, and who had 20/25 or better LogMAR distance visual acuity with manifest reaction in each eye and with +2.40 D add soft bifocal contact lenses in both eyes.
Children were randomly assigned Biofinity single-vision, Biofinity multifocal “D” with a +1.50 D add power or Biofinity multifocal “D” with a +2.50 D add power contact lenses.
Between October 17, 2014 and June 20, 2016, 443 subjects attended baseline visits to determine final eligibility and 294 subjects were enrolled.
On average, enrolled subjects had approximately -2.50 D myopia with 20/20 best-corrected visual acuity at distance and near.
The study is not powered to examine ethnic differences, according to researchers.
BLINK will be the largest and longest contact lens myopia control study performed to date, according to researchers.
“Although there is strong evidence that soft multifocal contact lenses slow myopia progression and axial elongation, little is known about the mechanism of the myopia control effect,” researchers wrote.
The BLINK study will provide a more thorough investigation into myopia progression and the optical ramifications of soft multifocal lenses, to date, according to researchers. – by Abigail Sutton
