ABSTRACT

 

Purpose
To confirm the prediction of emmetropization feedback theory that myopia can
be prevented by correcting the hyperopia of a child at risk of becoming myopic.
Methods
We conducted such myopia prevention treatment with twins at risk. Their
hyperopia was partially corrected by one half at age 7 and in subsequent years
until age 16.
Results
Hyperopia progressively decreased in all eyes as expected. None of the twins
developed myopia. The spherical equivalent refractions of the followed eyes
were +1 and +1.25 D at age 16. Feedback theory accurately predicted these
values.
Conclusions

The treatment of the twins with partial correction of their hyperopia was
successful. Prevention of myopia with this technique is relatively simple and
powerful. The use of this myopia prevention treatment has no adverse effects.
This prevention treatment is indicated in children with a hyperopic reserve at risk
of developing myopia.

Feedback Theory tested succesfully.

These two boys in green gowns were at risk of developing myopia, but are free of myopia and glasses at graduation (upper photo) after 9 years of preventive positive lens wear (lower photos). Their fellow student (middle) who had a similar visual experience but no preventive treatment developed several diopters of myopia in those years.
