Myopia control lenses is the most frequently used and the simplest method in myopia management, same as normal spectacles for correcting myopia.

To maximize the effectiveness of myopia control lenses, proper usage and good visual habits are essential. Myopia control consultants in Optical 88 will understand the myopia progression and visual needs of children. With illustration the lens design and myopia control mechanism, we help customers better understand our solution. We also give advices on frame selection and precise fitting, follow up regularly to monitor proper lens usage and evaluate the effectiveness.

Who is suitable for myopia control lenses?

  • Children who are too young or not able to handle contact lenses

Pros

  • The simplest method, just like wearing normal glasses
  • Clear central vision and easy adaptation

Cons

  • Effectiveness and visual performance subject to lens designs and wearing position
  • Peripheral field may be blurry or distorted (subject to lens designs)

Orthokeratology (Ortho-K lens)

Website_MC_Con

Orthokeratology (Ortho-K) is a technology for correcting refractive error by changing the shape of the cornea. It is a non-surgical treatment that requires wearing specially designed hyper-gas permeable contact lenses, it is proven to be effective in controlling children’s myopia progression1,2.

Wearing Ortho-K lenses overnight can reshape the cornea to temporarily reduce myopia and astigmatism and improve visual acuity. The reshaping effect of the cornea allows light entering the eyes to form “peripheral defocus”, delivering an effective way to slow myopic progression.

Who is suitable for Ortho-K treatment?

Children aged six or above and able to handle contact lenses

Myopia below -5 diopters and/or astigmatism under -2 diopters. (People with higher power are still applicable but they may need to wear glasses during the day)

 

Pros

  • No spectacles or contact lenses is need during the day in most cases
  • Avoid complications related to contact lens wear during the day
  • Avoid problems with spectacles, such as scratched lenses, loose frames or changed frame shape, these may affect vision and myopia control effectiveness

Cons

  • May lead to complications associated with contact lens wear, such as solution allergies, infection, corneal epithelial trauma
  • Users are advised to strictly follow the instructions given by optometrists and learn Ortho-K handling, such as lens insertion and removal and daily lens care
  • Frequent checkup at our Hong Kong centre is required

 

Is it risky?

Ortho-K may have adverse effects. However, if you maintain regular checkups and strictly follow instructions given by professional optometrists, you can minimize the risk. You can stop the treatment any time you want and the cornea will return to its original shape within a few weeks and the refractive error will come back as well.

Soft Contact Lenses for Myopia Management

Myopia control contact lens belongs to soft contact lens to wear in daytime. It provides an alternative for myopia control. Parents do not have to worry about dislocation or even damage of spectacles and children enjoy their daily lives and sports with wider field of view with no spectacles.

Concentric rings design allows part of the light to enter the eye and create myopic defocus, hence slow down myopia progression. The rest part of the light focuses on the retina provides clear image.

Who is suitable for myopia control contact lenses?

  • Children aged six or above and able to handle contact lenses
  • Astigmatism not more than -1.0 diopters. (People with higher power are still applicable but they need to wear glasses for astigmatism correction)

Pros

  • Better for sports comparing to spectacles
  • Avoid problems with spectacles, such as scratched lenses, loose frames or changed frame shape, these may affect vision and myopia control effectiveness

Cons

  • Children need to learn contact lens handling, such as lens insertion and removal and daily lens care
  • May lead to complications associated with contact lens wear, such as solution allergies, infection or corneal epithelial trauma.

Is it risky?

Wearing contact lenses may have adverse effects. However, if you maintain regular checkups and strictly follow instructions given by professional optometrists, you can minimize the risk.

Atropine for Myopia Control

Atropine for Myopia Control​

Recent researches showed that Low dosage Atropine (0.01 to 0.1%) eye drops is effective in controlling myopia progression with minimal side effects1, 2.  0.05% dosage was shown to slow down myopia progression by about 70% with only 1mm pupil dilation effect. It does not cause any discomfort in most of children2.

 

Who is suitable for Atropine?

It is suitable for children who are not allergic to atropine eye drops. (Must be prescribed by ophthalmologist to ensure it is suitable to use and there is no allergic response)

Pros

  • Easy to use, it only requires one eye drop a day
  • Combined treatment with other myopia control methods to achieve better effectiveness

Cons

  • No correction for myopia and astigmatism, children still need spectacle correction
  • few children may experience blurry vision and photophobia
