Doctor's answer:
Dilatation refraction is mainly used in the following situations: (1) Children under 12 years old. Because their accommodative ability is very strong, if refraction is not performed with dilatation, the error will be significant. (2) Myopic, hyperopic, or astigmatic patients aged 12 to 40. In principle, the first refraction should be performed with dilatation. During the second refraction, if the degree of correction does not change significantly, small-pupil refraction can be conducted based on the original degree of correction. (3) When both the fundus and refractive media examinations are normal, but vision is poor, dilatation refraction is used to rule out refractive errors. (4) Complex refractive errors, such as high myopia, high hyperopia, or high astigmatism, or myopia or hyperopia combined with astigmatism. (5) Unstable vision in adolescents, where vision fluctuates between good and poor, and suspicion of pseudomyopia. In such patients, once dilatation is performed, accommodative ability disappears, and pseudomyopia is eliminated accordingly.
