I. Adaptation to children with very poor visual acuity Because the training icons provided by the conventional amblyopia treatment instrument are very few around 0.1, and the fineness of the visual scale changes is small, the children can not see the largest visual acuity icons or can only see a few of the largest icons, and most of the visual acuity training icons are in the invalid state of not being able to see, and the few icons that can be seen can easily be remembered, resulting in boring and poor results, which can easily delay the disease. The personalized treatment program of Dr. Eye has the following features: 1. Using a high-precision threshold visual acuity checklist of 0.01-0.5 with a fineness of 0.002-0.004 to find out the threshold visual acuity and personalize the “threshold icon amblyopia treatment instrument” according to the check results. If you don’t cooperate and can’t find out the visual acuity, you can customize the corresponding “threshold icon amblyopia treatment instrument” according to the visual acuity below 0.05. 2.Additional auxiliary vision enhancement mirror to improve the level of recognition of the threshold visual acuity, further reducing the difficulty of improving visual acuity. The younger the child, the better the effect of vision enhancement, but the worse the cooperation, which may delay the best time for treatment due to the inability to cooperate with the examination and treatment. The personalized modular treatment method of Dr. Eye can solve this problem: for children whose visual acuity is lower than 0.1, they cannot check the accurate visual acuity with the ordinary visual acuity table, and must use the “low visual acuity threshold visual acuity table” instead. If they cannot cooperate, they will be treated as having a visual acuity of 0.05 or less. For children who are too young to cooperate with the instrument, Professor Liu Dongguang invented the “hooded” amblyopia instrument, which can be worn on the child’s head, so that he or she can be placed in a dark environment for vision enhancement training regardless of his or her head tilt or other uncooperative movements. The danger of strabismus is not only that “strabismus” damages appearance, but more importantly, it can destroy the advanced visual function of binocular monovision (i.e., simultaneous vision, fused vision, stereopsis). Although a skilled strabismus surgeon can correct the strabismus well, there is no guarantee that it will not recur after surgery, and one of the main reasons for recurrence after strabismus surgery is the failure to establish or improve the monocular dysfunction of both eyes caused by strabismus in time. Therefore, in order to prevent the recurrence of postoperative strabismus and to establish and improve the advanced binocular monovision function, every postoperative child with strabismus (if there is such dysfunction) should start binocular monovision rehabilitation training as early as possible, using binocular monovision function to stabilize the eye position, and then using individualized threshold visual markers for vision enhancement training.
