iseikonic lens? need help.

Hi,

Iam a independent Optometrist from China, and I am looking forward for your help.

We have a 6-year-old patient with congenitaleye disease, where one eye has high myopia, and the other still hassome hyperopia reserve. As it is known as anisometropia. The eye withmyopia has severe amblyopia, and the patient is undergoing visualtraining to improve their vision at medical institution. The currentprescription for the patient is as follows:

eye	sphere	cylinder	angle
OS	-6.25	-1.50	30
OD	+1.50	0	180

When using spectacles with such a large difference in sphere power, the difference in the size of objects viewed by the two eyes is significant, affecting the fusion of images and hindering visual recovery. However, due to the patient's age and cooperation, it is unable to use contact lenses for now.


We have tried domestically available technology, which adjusts magnification by slightly modifying the thickness of the lens, makingthe size of objects viewed by each eye closer. However, these lenses are not designed specifically for the patient, and the imaging difference is still significant. Additionally, there is an obvious prism effect in the vertical direction, causing significant height differences in the images.

Through the internet, I heard about slab-off (or any other ?) technology, which can optimize for above situation.

1, Is there any appropriate technology that can overcome the imaging difference problem in eyeglasses and provide them to patients with this condition?

2,Considering factors such as lens thickness or weight, to what extent can imaging differences be repaired?

3,If such a product exists, what is the approximate price, and where toorder them?

4,What measurements do we need to take to configure such lenses for thepatient?



any infomation may help ,thanks
