How long it takes for the pupil to return to normal when dilated by dilating medication depends on the type of medication used. There are two types of dilating medications: fast dilating and slow dilating, and two types of fast dilating: Medrol fast dilating and Safije fast dilating. Medrol fast dilatation has a faster recovery time, routinely 6-8 hours, and the pupil will return to normal. Safije is a little slower than Midori, although it is also a fast dilator, but the pupil recovery time is about 1-2 days. Atropine is a slow pupil dilatation. Atropine requires 3 consecutive days of pupil dilatation and an optometry on the 4th day, but it takes about 3 weeks for the pupil to recover, and then 3 weeks for the pupil to return to its normal size before it can look closer. The pupil recovery time should be judged according to the dilating medication ordered.
