Intervention - Correction
Children with shortsightedness need to be fully corrected. No scientific reported undercorrection can slow down myopia progression. On contrary, undercorrection may induced a small but insignificant increase in myopia progression compared to full correction18, 19.
Intervention - Myopia Control
MiSight™ is one of the options for myopia control available in the market.
MiSight™ : A Daily Disposable Contact Lens
One day contact lens: free from complicated cleansing procedure
Lens made of Proclear® material: effective in locking in moisture and providing more than sufficient oxygen for daily wear
Correct shortsightedness (nearsighted) while help reduce the progression of myopia
MiSight™ - ActivControl™ Technology
ActivControl™ Technology combines two optical systems that provide:
Clear Distance, Intermediate and Near Vision
Treatment Zones that can slow down the rate of progression of myopia
What is ActivControl™ Technology
A technology that delivers dual optical properties
an optic for vision correction and
an optic to control myopia progression
ActivControl™ Technology creates myopia defocus to control myopia progression.
Myopia defocus treatment effect: Distribution
Efficacy - Myopia progression21:
Average reduction was 0.30D/yr (p<0.01)
75% of the treatment eyes received ≥ 30% reduction in myopia progression
20% of the treatment eyes stopped myopic progression
Myopia defocus treatment effect: Eyeball length
Eye growth responses to the myopic retinal defocus treatment at commencement (Slope A)
Once the lens wear is discontinued, the eye will progress with its normal rate (Slope B)
However, the treatment effect already received will remain20 and did not develop into slope of C
