I'm just wondering how atropine is used to detect refractory power while accomadation is intact? I think atropine should disturb accomadation!!

Topical atropine is used as a cycloplegic, to temporarily paralyze accommodation, and as a mydriatic, to dilate the pupils. Atropine degrades slowly, typically wearing off in 2 to 3 days, so tropicamide and phenylephrine is generally preferred as a mydriatic. In atropine-induced mydriasis, the mechanism of action involves blocking the contraction of the circular pupillary sphincter muscle which is normally stimulated by acetylcholine release, thereby allowing the radial pupillary dilator muscle to contract and dilate the pupil. Atropine is contraindicated in patients predisposed to narrow angle glaucoma.
