ZEISS MyoCare – New myopia control lens
ZEISS MyoCare is the latest myopia management lens from ZEISS Vision Care. The efficacy of ZEISS MyoCare has been demonstrated in their long term study involving more than 1000 children. We believe the efficacy of MyoCare would be close to the efficacy of Stellest and Hoya MiYOSmart which is about 60%.
ZEISS MyoCare will be launched in Europe from April 2023 and should be available in Singapore in the coming months.
ZEISS MyoCare Portfolio
ZEISS MyoCare is the first age-related myopia management lens solution.
It’s backed by ZEISS innovation and more than a decade of experience in developing lenses aimed to manage myopia progression.
ZEISS’s MyoCare Portfolio consist of 2 lens designs for separate age groups.
- MyoCare
- MyoCare S
According to clinical evidence:
- The design of MyoCare is more effective in younger age groups while
- The design of MyoCare S is more effective in older age groups
Both MyoCare and MyoCare S incorporate:
C.A.R.E Technology (Cylindrical Annular Refractive Elements)
- Aimed to deliver a ‘stop signal’ to slow down progression of axial elongation
- Consist of alternating defocus and correction zones in a ring-like pattern on the front surface, expanding towards the periphery of the lens
ZEISS ClearFocus design
- Aimed to remove the ‘growth signal’
- The optimised back surface delivers the refractive correction and intended myopic defocus of the patient for all gaze directions.
According to ZEISS’s study:
- 98% of children claimed that their distance and near vision is very good when wearing ZEISS MyoCare designs
- 100% of children adapted to the lenses within one day
ZEISS C.A.R.E. technology
An effective myopia management lens must find the optimum balance between myopia progression management and good vision.
For this, ZEISS have included the following in it’s myopia management solutions:
- Clear central zone for clear and sharp vision
- Cylindrical Annular Refractive Elements (C.A.R.E), microstructures, which introduce myopic defocus with a fill factor
- Functional zone consist of almost invisible concentric circles with alternating defocus and correction zones
ZEISS ClearFocus design
With the ZEISS ClearFocus design, both the optimal refractive correction according to the your child’s refractive demands and the intended myopic defocus are maintained for all gaze directions.
This is important for:
- Distinct viewing behaviours through the central clear zone when pursuing a focused task
- Unintended gazes to the lens periphery
In summary, the ZEISS ClearFocus design featured in MyoCare lenses effectively minimizes unwanted hyperopic defocus for all viewing angles.
ClearFocus design
- Aimed to effectively minimize the induction of hyperopic defocus
- Ensures that the focus remains close to the intended focus shell, i.e., close to the retina
In summary, the ZEISS ClearFocus design featured in MyoCare® lenses effectively minimizes unwanted hyperopic defocus for all viewing angles.
Emmetropic progression ratio
Emmetropic progression ratio is a new approach to measure effectiveness.
Each myopia progression management intervention has its own advantages and disadvantages, however each option pursues a common target: To slow down myopia progression.
The ZEISS MyoCare designs show an average emmetropic progression ratio for axial length of:
- up to 86% for children aged 10-12 years
- up to 63% for children aged 7-9 years
ZEISS MyoCare designs effectively slow down myopia progression to come closer to the physiological growth curve.
Emmetropic progression ratio
Age-normal physiological growth curves
- The aim is to follow or to be as close as possible to the age-normal physiological growth curves of emmetropic children.
Emmetropic progression ratio as a percentage of effectivity
- An indication of how close children with the intervention are coming to the emmetropic growth curve in contrast to the myopic growth curve.
ZEISS MyoCare designs effectively slow down myopia progression to come closer to the physiological growth curve
MyoCare, Stellest and MiYOSMART
All these 3 myopia control lenses use myopic defocus to control myopia progression.
However, their lens design and technology used to design the lenses are different.
For MyoCare, it uses concentric circles with alternating defocus and correction zones and C.A.R.E. Technology.
For Stellest, it uses a constellation of aspherical lenslets on 11 rings and H.A.L.T Technology.
Lastly for MiYOSMART, it uses hundreds of small segments of constant myopic defocus evenly distributed in honeycomb structure and D.I.M.S Technology.
In terms of lens material, MyoCare offers polycarbonate and plastic lenses with refractive index of 1.67 which will gives you a thinner and lighter lens. This is suitable for children with high myopia and wants their lenses to look thinner and feel lighter.
Whereas for Stellest and MiYOSMART, they use polycarbonate lens with only one refractive index which is a impact resistance lens. This is suitable for kids who are more rough with the handling of their glasses.
ZEISS MyoCare will be launching in Singapore and should be available at Evershine Optical in the coming months. Follow us on instagram or facebook for updates on the availability of ZEISS MyoCare in Singapore. (update : ZEISS MyoCARE is now available at Evershine Optical )
