Myopia Control with MiSight

Currently, it’s estimated that about 30% of the world’s population has myopia, and by the year 2050, that number is expected to grow to 50%. The treatment with Misight soft disposable contact lenses is designed with a treatment zone and correction zone to slow the growth of the length of the eye and by the strength of the prescription.

Description: The treatment zone defocuses the light ray in front of the eye while the correction zones direct the light ray directly to the retina for clear vision. Image provided from Coopervision.

Who is a candidate for MiSight Myopia Control?

• A child who is near sighted and showing an increase in prescription between eye exams.

• Children 8-12 years old (Optimal results when treatment is initiated at this age).

How does MiSight work?

MiSight technology helps slow the elongation of the eye and myopia progression while fully correcting for refractive error. There are two treatment zones that create a myopic defocus with the image focusing in front of the retina rather than behind it to slow axial elongation. The dual optics of the two correction zones correct the myopia in all gazes.

The goal of the treatment is to reduce myopia progression by decreasing the rate of the axial growth (or elongating eye). Over a three year clinical trial, MiSight reduced myopia progression in children by 59% compared to a regular single vision daily disposable lens. There was also a 52% reduction in average axial lengthening.

What is Myopia?

Myopia is when the eye is elongated and a person cannot see things from far away. Their near vision is clear, but need to rely on glasses to help them see things in the distance. Genetic and environmental factors play a role in a child’s eye development. Children who have parents that are near sighted are likely to become nearsighted. Other risk factors include: low outdoor time and near work, dim light exposure, low sleeping hours, reading distance less than 25cm and living in an urban environment. Prevalence of myopia worldwide in school children aged 6-19 years: North America (42%), Asia (60%), Europe (40%), East Asia (73%).

Why is it important to prevent myopia progression?

These are vision threatening conditions associated with increasing myopia:

• Retinal detachment

• Glaucoma

• Cataract

• Myopic retinopathy
