Myopia management or myopia control is a term to describe specific treatments to slow the progression of near-sightedness in children. Our services of myopia management included:
- Soft multifocal contact lens
A multifocal contact lens designs can be used to slow the progression of myopia with efficacy ranges from 40% to 60% for 1-2 years. The effect of slowing myopia progression became obvious when children wore the lenses for five hours a day, and the improvement increased if they wore them for seven hours a day or more.
- Rigid gas permeable (RGP contact lens)
In a three-year study of more than a hundred 8- to 11-year olds in the December 2004 issue of the journal Archives of Opthalmology, researchers determined that wearing rigid gas permeable (RGP) contact lenses slowed the progression of myopia by nearly 30 percent, compared to soft contact lens wear.
- Orthokeratology lens
Orthokeratology is an overnight process to reshape the cornea, with special RGP lens to reduce refractive power becomes almost plano or zero power. The efficacy ranges also within 40% to 60%. Patient with this treatment only wear contact lens during overnight sleep and do not have to wear any correction during the day.
- Progressive lens
A lens that have been used for myopic children to slow the progression of myopia; especially for children with accommodative lag during near work experience hyperopic retinal defocus which lead to axial elongation.
