How long should 0.01% atropine sulfate eye drops (EIKANCE) be used for the best effect?

0.01% Atropine Sulfate Eye Drops (EIKANCE) is clearly positioned in the guidelines as a "long-term management" myopia intervention program. Its effect is not visible in the short term, but depends on continued use. To determine "how long to use it for the best effect", it is necessary to comprehensively understand the development rules of children's eye axis, drug mechanism and international long-term observation trends.

The key problem of children's myopia is that the axial length of the eye is too rapid. The growth rate is most obvious from 6 to 12 years old, and will gradually slow down after the age of 12. Therefore, most overseas experts believe that low-concentration atropine should cover the "rapid growth stage of the axial length" to obtain the maximum protective benefit. The value of EIKANCE lies in its long-term stable intervention, which delays the growth trend of the axial length at the critical stage.

Judging from international long-term use experience, most children need to observe at least 6 to 12 months after using 0.01% to see trend changes, but this is only "the effect appears." The true "optimal use cycle" often takes longer, and is usually aimed at "covering the entire period of rapid growth". Ophthalmology guidelines in many countries recommend continued use for 2 to 3 years, or even longer, to achieve maximum intervention effectiveness. This is because myopia is a long-term condition rather than a short-term symptom, so the treatment logic is closer to chronic management than short-term correction.

It needs to be emphasized thatThe "best effect" does not mean that vision is improved, but that the axial length of the eyeball is slowed down and the progression of myopia is reduced. This trend has individual differences, so doctors will develop an individualized service life based on factors such as the child's age, axial length, family history of myopia, and habits. In some children, the axial growth of the eyeball becomes stable after taking the medication for several years, and the dosage can be gradually reduced or discontinued under the advice of a doctor; other children may need to continue taking the medication for a longer period of time.
