Autorefractor Accuracy in Children

As nearsightedness spreads to younger generations, autorefractors are now at the forefront of detecting early signs of myopia.

As technology increasingly becomes a part of our everyday lives, myopia (nearsightedness) is on the rise, particularly in pediatric populations. According to the American Optometrists Association, 1 in 4 parents have reported that their child has the condition. Now more than ever, it’s important to check on your child’s vision health. 

Nearsightedness affects nearly 2.6 billion people worldwide and occurs when the eye becomes deformed. While its effects may be hard to reverse, myopia can be easily detected by getting your eyes checked for refraction errors. Lengthy eye exams can be difficult for children to sit through, but autorefractors (AR) now offer an easy solution. With autorefractors, we can now detect refraction errors in children in as short as five minutes.

The study investigated findings in both cycloplegic (eyes paralyzed for the measurement) and noncycloplegic conditions for children. 

In noncycloplegic environments, only SVOne and Grand Seiko WAM were able to produce a mean difference in spherical equivalent or sphere of less than 0.25 diopters (D) from cycloplegic retinoscopy results. These devices are able to so closely reproduce these results due to their open channel design during refraction. This design allows them to then reduce accommodation errors. 

Autorefractors are a quick and accurate solution to the growing demand for eye checkups for children. With this device, we’re now able reproduce clinically accurate measurements in short amounts of time. This technology will allow us to widely test large pediatric populations in anywhere from schools to remote rural areas.
