What was the first study that showed the use of contact lens for myopia control in children?
Best insight from top research papers
The first study that showed the use of contact lenses for myopia control in children was conducted by Shen et al.. They conducted a prospective, multicenter, randomized, double-masked, placebo-controlled clinical trial to assess the safety and efficacy of an extended-depth-of-focus (EDOF) soft contact lens for myopia control in children. The study involved 72 children aged 9 to 14 years, and each eye was randomly assigned to wear either the experimental EDOF contact lens or a single-vision control lens. After 52 weeks of wearing the lenses, the results showed that the EDOF lens significantly reduced myopia progression and axial length elongation compared to the single-vision lens. This study demonstrated the potential of contact lenses, specifically the EDOF lens, as an effective method for controlling myopia in children.

What are the most common myopia control methods used in Hong Kong?4 answersThe most common myopia control methods used in Hong Kong include atropine eye drops, pirenzepine eye gel, orthokeratology, peripheral defocus contact lenses, bifocal or progressive addition spectacles, and increased outdoor activities. Additionally, Defocus Incorporated Soft Contact (DISC) lenses have shown significant effectiveness in slowing myopia progression and axial elongation in Hong Kong schoolchildren, with a 25% slower myopia progression and 46% less progression in children wearing DISC lenses for five or more hours per day compared to single vision lenses. These methods aim to mitigate myopia progression, which is crucial in preventing vision-threatening complications associated with high myopia, given the high prevalence of myopia in both children and parents in Hong Kong.
How age related to myopia?5 answersAge is closely related to myopia. Studies have shown that the age of myopia onset is an important factor in the development and progression of myopia.Early age of myopia onset has been found to be associated with a higher risk of developing high myopia later in life.In addition, the prevalence of myopia has been found to increase with age, with a higher prevalence observed in older age groups.However, there is also evidence of a decrease in myopia with increasing age in some studies, followed by an increase in myopia in the very old age group.These findings suggest that age plays a complex role in the development and progression of myopia, and further research is needed to fully understand the relationship between age and myopia.
Is myopia genetic?5 answersMyopia, or nearsightedness, has a strong genetic component. Multiple studies have identified over 500 genetic loci associated with refractive error and myopia. Genetic testing has revealed various risk variants in individuals with high myopia, particularly in younger populations. Lifestyle factors, such as excessive near work and limited outdoor time, also contribute to myopia development, but genetics play a significant role. The prevalence and severity of myopia are higher among East Asians, suggesting a genetic predisposition in certain populations. Furthermore, the genetic risk of myopia has been found to increase as latitude decreases, indicating a potential role of local adaptation to sunlight exposure. Whole exome sequencing has been successful in identifying genetic causes of high myopia, even in cases without apparent clinical features. In conclusion, myopia is influenced by both genetic and environmental factors, with genetics playing a significant role in its development and progression..
When were contact lenses first used for myopia control in children?5 answersContact lenses were first used for myopia control in children in a study conducted by Padmaja Sankaridurg et al.. The study aimed to determine the myopia control efficacy of novel contact lenses that reduced both central and peripheral defocus and provided extended depth of focus with better global retinal image quality. The study enrolled children aged 8-13 years with cycloplegic spherical equivalent (SE) -0.75 to -3.50D. The trial commenced in February 2014 and was terminated in January 2017 due to site closure. The results showed that all test contact lenses had reduced myopia progression compared to control contact lenses, with a reduction in axial length elongation of about 22% to 32% and a reduction in spherical equivalent of 24% to 32%. Therefore, the use of contact lenses for myopia control in children was first explored in the study conducted by Padmaja Sankaridurg et al. in 2014-2017..
What are the current contact lenses used to reduce myopia progression in children?5 answersMultiple segment (MS) spectacle lenses and dual-focus contact lenses have been used to reduce myopia progression in children. MS lenses, such as MiyoSmart or DIMS and Stellest, have shown effectiveness in controlling myopia progression over a period of at least 2 years. Dual-focus contact lenses, like MiSight®, have also been clinically proven to control the progression of myopia in children and have been approved by the US Food and Drug Administration (FDA). Additionally, drug-eluting contact lenses, such as atropine-eluting contact lenses, have been explored as an alternative for controlling myopia progression. Furthermore, multifocal contact lenses (MFCL) with different add powers, such as Multistage + 1.50D and Proclear + 3.00D, have been found to slow myopia progression and axial length elongation in myopic schoolchildren. Finally, dual-focus soft contact lenses, like MiSight 1 day, have been shown to sustain slowed progression of myopia over a 6-year treatment period.
What are the risks and benefits of contact lens wear in infants with aphakia?3 answersContact lens wear in infants with aphakia has both risks and benefits. The benefits include improved visual outcomes compared to glasses, as contact lenses provide optimal visual correction and can be customized. They are also associated with better adherence and wearing compliance compared to spectacles. However, there are risks associated with contact lens wear. Adverse events such as microbial keratitis, corneal infiltrates, and corneal edema have been reported with silicone elastomer (SE) lenses. Additionally, infants who undergo intraocular lens implantation experience more frequent complications, such as visual axis opacification, compared to those treated with contact lenses. Despite these risks, contact lenses have been successfully worn by infants with relatively few adverse events. It is important for caregivers to closely monitor and ensure proper lens care to minimize the risks associated with contact lens wear in infants with aphakia.
