The recovery time for dilated eyes depends on the type of dilating agent. In the case of rapid dilators, the recovery time is 6-8h; in the case of chronic dilators, the recovery time takes 20-25 days. There are 2 common types of dilators, the rapid dilator is compound tropicamide ophthalmic solution, and the chronic dilator is atropine ophthalmic ointment or atropine gel. Clinical dilation is commonly used for optometry in patients under 18 years old, and chronic dilators are needed for patients under 10 years old, and rapid dilators are needed for patients between the ages of 10 and 18. Dilatation is also commonly used for eye examinations, including lens vitreous fundus examination. Dilatation is also commonly used for inflammatory conditions of the eye, such as uveitis. Dilating the pupil paralyzes the ciliary muscle, reducing inflammation and pain.
