"   What is it used for?  Dilating the pupil to allow easier examination inside the eyeball. Relaxing the muscles in the eye when vision is being tested.  To dilate the pupil or relax the eye before or after eye surgery.    How does it work? Mydriacyl eye drops contain the active ingredient tropicamide, which is a type of medicine called an anticholinergic (or antimuscarinic). It is used to aid eye examinations. Tropicamide blocks muscarinic receptors in the muscles of the eye. These receptors are involved controlling the size of the pupil and the shape of the lens. By blocking these receptors, tropicamide causes the pupil to dilate (mydriasis), which it makes it easier to examine structures inside the eyeball, such as the retina, optic disc, macula and fovea. This is called fundoscopy. Tropicamide also temporarily paralyses the muscles that help the eye focus (cycloplegia), which is used to aid tests on vision (cycloplegic refraction). One or two drops will be put into the eyes 15 to 20 minutes before the eye exam. The effect of these eye drops lasts for about four to six hours.   Warning!  These eye drops can cause blurred vision, difficulty focusing and sensitivity to light. The effects can last for four to six hours.
