Mydryn Eye Drop is used before eye examinations and to treat an eye condition called uveitis. It acts by enlarging the pupil of the eyes and helps the doctor visualize the eye more closely. It reduces redness and swelling in the eyes after cataract surgery. Mydryn Eye Drop is for external use only. Use it in the dose and duration as advised by the doctor. Refrain from touching the tip of the dropper to any surface to avoid contaminating the eye drops. The common side effects include burning and stinging sensation immediately after application. These are usually temporary and resolve with time. Using Mydryn Eye Drop can make your eyes more sensitive to light. Thus, wear sunglasses to protect your eyes from sunlight and other bright lights. Avoid driving right after using this medicine as it may cause blurring of the vision.
