An Ortho-K Lens

An Ortho-K Lens

Today it’s possible to tailor any products to peoples’ specific needs,

and contact lenses are not being overlooked.

During the 2021 SOA-AOC e-Symposium Dr. Ngoc Hoang demonstrated a special orthokeratology lens

(or Ortho-K) and shared results of recent studies regarding its effectiveness.

With a PhD in biotechnology from the Tokyo Institute of Technology,

 Dr. Hoang is currently involved in the Clinical Affairs Department at Japanese vision company SEED, ลาวสามัคคี วีไอพี

where she helps facilitate clinical trials of their lenses in Japan and abroad.

She has brought experience in evaluating several types of contact lenses from SEED and other manufacturers.

 Let’s have a glance at how SEED’s overnight corneal shaping lens is particularly suitable for East Asian eyes, in particular.

The rise of myopia in Asia Dr. Hoang reports that in 2010 about 25% of the global population had a form of myopia.

With numbers increasing by 5% each decade, by 2050 half of the world is expected to be near-sighted.

Yet in Asia, the numbers are more extreme, with studies showing East Asians being more susceptible to the epidemic.

In Singapore, the prevalence of myopia is among the highest in the world, with 65% of children being myopic by 6-years-old; and

by 2050 it’s predicted that 80-90% of all Singaporean adults will have some form of the disease.

More alarmingly, the COVID-19 pandemic appears to have had an effect on myopia development,

most notably in young children who have been forced to have more screen time per day and who are no longer spending time outside walking to and from school.

Citing a 2019-2020 study from China, the biotechnology expert explained that due to children staying home for school,

 the rate of refractive error of children aged 6,7 and 8-years-old was significantly worse and the number of myopic children increased 3x, 2x and 1.4x respectively.

“The reason why myopia is a major public health concern,” Dr. Hoang warns, “is because myopia is not just a refractive error

… there are some side threatening complications such as cataract, retinal detachment and myopic maculopathy.”

Fortunately, the use of Ortho-K lenses prevents myopia and can help prevent its associated health risks

by reshaping the cornea; it’s particularly effective for children who do not yet have high myopia.
