Do you know the 3 latest methods to prevent worsening of myopia in Hong Kong children?

Myopia rate among children in Hong Kong

The myopia rate among Hong Kong children increased with age, from 6.3% of pre-school children to 18.3% at age 6 and 61.5% at age 12, while the prevalence of myopia among adults aged 21-30 was 84.7%.

If you develop deep myopia, the risk of developing different eye diseases, such as retinal detachment, cataracts, glaucoma, and yellow class disease, will be greatly increased when you grow up.

The purpose of childhood vision correction is not to stop the progression of myopia completely, but to slow down the progression of myopia.

Myopia prevention

If a child increases myopia by 100 degrees per year, it is considered to be treated for treatment, and the ideal rate of myopia progression for children is within 50 degrees per year.

Low-dose atropine eye drops are commonly used by ophthalmologists in recent years as the first line to slow myopia in children.

Research by CUHK has shown that this method can effectively slow the progression of myopia in children by up to 60%, and side effects are rare.

IN ADDITION, A MULTI-ZONE FORWARD OPTICAL DEFOCUS (DIMS) SPECTACLE LENS DESIGNED BY THE HONG KONG POLYTECHNIC UNIVERSITY WAS SHOWN TO SLOW THE PROGRESSION OF MYOPIA IN THE PARTICIPATING CHILDREN BY UP TO 60%.

Spectacle lenses consist of a "central optical zone" to correct refractive errors and a "multi-zone continuous myopia defocus" that extends around the central area to the perimeter of the lens.

WHEN THE WEARER IS VIEWING OBJECTS AT DIFFERENT DISTANCES, DIMS SPECTACLE LENSES PROVIDE CLEAR VISION AND MYOPIA DEFOCUS TO CORRECT VISION AND HELP SLOW THE PROGRESSION OF MYOPIA.

FINALLY, CHILDREN CAN CHOOSE TO WEAR ORTHOKERATOLOGY LENSES (OK LENSES).

It uses special rigid orthopedic contact lenses and tear tension to change the curvature and shape of the cornea.

Children who receive orthopedic vision correction only need to wear orthopedic lenses at night to sleep, but the advantage is that they do not need to wear glasses in the morning.

The only concern is that children unconsciously pinch their eyes during sleep and cause corneal damage or infection, so this method is only suitable for children over 8 years old who have good self-care ability.
