Myopia remains stable in 23 % of MiSight study participants
Nearly a quarter of the children participating in a clinical study for CooperVision ’ s MiSight 1 day contact lenses experienced no myopia progression after six years , according to the latest findings .
“ Evaluating children who were prescribed MiSight 1 day at the study ’ s initiation , 23 per cent of eyes after Year 6 displayed a total refractive change of less than -0.25D ( spherical equivalent ), which could be considered clinically stable ,” says Paul Chamberlain , CooperVision ’ s director of research programs .
“ There is now even more reason to recognize the substantial capability of this unique dual-focus contact lens .”
should get his eyes looked at . We took him to the eye doctor and we found out that not only was he myopic , but that it was progressing extremely quickly due to the fact that he had these extended periods on these screens .
Q . What do you like about CooperVision ’ s MiSight 1 day ?
A . There are two things that I think are incredibly important about CooperVision ’ s MiSight . One is the opportunity to slow the progression ; that ’ s not something that existed for me at that age . So anything I can do that would slow that progression for my son , I want to .
But , also , the idea of a contact lens that ’ s disposable , that ’ s daily , that the kids aren ’ t worried about getting dirty or losing and that he doesn ’ t feel different about the way he looks and he can continue to do his sports and he doesn ’ t feel impacted really at all by the diagnosis .
Q . Will your son be using MiSight 1 day ?
A . At our next appointment , we will be seeing if he is a candidate . We ’ re excited ; he ’ s excited .
Q . What excites you about your collaboration with CooperVision ?
A . For me , everything ’ s about education and knowing what the options are . For me , it ’ s about being able to use my platform to share that information and hopefully have other parents notice the signs earlier than I did with their kids and know what to look for . OP
CooperVision shared the latest findings of its clinical study in the fall during the American Academy of Optometry ’ s virtual annual meeting .
The findings also suggested that while intervention at an early age is optimal with MiSight 1 day , starting treatment at an older age can similarly slow the rate of myopia progression .
The original control group was refit into the dual-focus lens in Year 4 . Comparing this population to the children fit with MiSight 1 day at initiation , there have been similar rates of myopia progression and axial length growth in the subsequent three years of assessment , CooperVision says .
In addition , the six-year results continued to demonstrate excellent safety profile , wearing time and visual acuity for children in daily disposable contact lenses over 653 wearing years . No other prospective randomized controlled study has offered conclusive data for such a high degree of continued efficacy in myopia management using a soft contact lens over a similar time span .
MYOPIA FACTS
Also known as nearsightedness or short-sightedness .
• A very common visual condition that affects nearly 30 per cent of Canadians .
• Normally begins in childhood and continues to increase until the individual reaches the age of 20 .
• Projected to affect the vision and increase risks to ocular health of approximately five billion people by 2050 , more than doubling today ’ s numbers .
• Has been linked to sight-threatening conditions later in life such as cataracts , retinal detachment , glaucoma and myopic maculopathy .
