SAN RAMON, CALIF., Nov. 2, 2021CooperVision, a world leader in myopia control and management for children, today announced new seven-year findings from its international pivotal MiSight® 1 day contact lens clinical trial. Twelve months following treatment cessation, mean axial elongation data indicate no study subject showed evidence of rebound, meaning the myopia control gains are retained.1,2


The study is the world’s longest continuous running soft contact lens clinical trial for myopia control. CooperVision previously reported that MiSight® 1 day showed sustained slowing of myopia progression across multiple years of treatment. This was observed in a cohort that wore MiSight® 1 day for the study’s first six years as well as the original control group who were switched into MiSight® 1 day for three years.3


“Our unparalleled research clearly illustrates the tremendous potential of MiSight® 1 day for children of different ages and with different levels of myopia, regardless of when they start treatment.3 With these results, eye care professionals should be even more confident in prescribing MiSight® 1 day,” said Paul Chamberlain, BSc (Hons), MCOptom, the study’s principal investigator and CooperVision Director of Research Programs.


The latest data analysis goes even deeper to illustrate that MiSight® 1 day offers a highly-desired proportional myopia control treatment effect. Abnormal axial length growth slowed by an average of approximately 50% with all tested ages (8-17).4  Because younger children’s myopia progresses faster than in older children,5 introducing MiSight® 1 day at the earliest opportunity may offer the maximum cumulative benefit over time.4


In the study’s seventh year, participants were transitioned from MiSight® 1 day to a single vision contact lens to evaluate if treatment gains would be retained. Myopic progression then occurred only at anticipated ‘age-normal’ levels—not at an accelerated “catch up” rate that would offset prior myopia control gains.1,2 This indicates study subjects showed no rebound effect.


"We saw these children grow into young adults during their seven years in the study. It is personally as well as professionally fulfilling to know that the benefits of treatment are retained. As MiSight® 1 day becomes more widely available and as myopia management becomes the standard of care, I hope other eye care professionals will experience that same joy," said study investigator Nicola Logan, PhD, Professor of Optometry and Physiological Optics, Aston University.


MiSight® 1 day contact lenses are specifically designed for myopia control and are FDA* approved to slow the progression of myopia in children aged 8-12 at the initiation of treatment.In August, MiSight® 1 day received approval from the Chinese National Medical Products Administration (NMPA) to become the first indicated product of any type that may slow the progression of axial length.§


CooperVision researchers are sharing their findings at this week’s American Academy of Optometry Annual Meeting, the globally-renowned scientific and clinical conference. For more information, visit

Disclaimer: The stability of the myopia reduction effect 1-year post-treatment is being further evaluated in a post-approval study in the U.S. as a condition of FDA approval of MiSight® 1 day.


Preliminary international study data shows that, on average, for children that discontinued treatment at age 14-19 following 3 or 6 years of MiSight® 1 day wear, the eye growth reverted to age-expected average myopic progression rates.


U.S. Indication for Use: MiSight® 1 day (omafilcon A) soft (hydrophilic) contact lenses for daily wear are indicated for the correction of myopic ametropia and for slowing the progression of myopia in children with non-diseased eyes, who at the initiation of treatment are 8-12 years of age and have a refraction of -0.75 to -4.00 diopters (spherical equivalent) with ≤ 0.75 diopters of astigmatism. The lens is to be discarded after each removal. Canadian Indications for Use: MiSight (omafilcon A) Soft Contact Lenses for Myopia Control may reduce the rate of myopia progression in children (6-18) and correct ametropia.  Reduction of myopia progression was observed in children with wearing time of 12 hours (8-16 hours) per day, 6.4 days (5-7) per week in a clinical study.  Permanent myopia control after lens treatment is discontinued is not supported by clinical studies. MiSight (omafilcon A) Soft Contact Lenses for Myopia Control are indicated for single use daily disposable wear.  When prescribed for daily disposable wear, the lens is to be discarded after each removal.


Compared to a single vision 1 day lens over a 3-year period. Fitted at 8-12 years of age at initiation of treatment.


§ China Indications for Use: MiSight® is indicated for the correction of myopia for patients with non-diseased phakic eyes, who at the initiation of treatment are 8-12 years of age and have a refraction of -0.75 D to -4.00 D with ≤ 0.75 diopters of astigmatism. Its dual focal design with alternative multiple rings allows part of the light passing through the optical zone to focus in front of the retina, forming myopic defocus and is expected to slow axial length progression of patients. Fitting and evaluation of the product should be in medical institutions by ophthalmologists with an intermediate title or above, including regular evaluations. It must be used in strict accordance with the IFU requirements.
