Povidone-iodine in the eye will not normally harm the eye as long as it is handled correctly, but if it is not handled correctly, it may damage vision. If povidone-iodine accidentally enters the eye, it should be handled immediately, and immediately washed with a large amount of water or saline, which can dilute the povidone-iodine and help to expel it, and will not cause too much damage to the eye, nor will it affect the eyesight. If you can’t wash the iodophor immediately after it enters your eyes, because the iodophor is in contact with the conjunctiva and cornea for too long, it will cause the corneal epithelium to peel off and irritate the conjunctiva, resulting in redness of the eyes, tingling, and blurred vision and other symptoms. Especially the high concentration of iodophor can cause great damage to the eyes. After iodophor gets into the eye, it should be washed promptly, and if the situation is not relieved, go to the hospital to be treated by a professional doctor.
