When will the blurred vision pass after using Diprophos?

This symptom may not go away on its own and it is necessary to consult a doctor, preferably an ophthalmologist. According to the manufacturer: "Visual disturbances may occur as a result of systemic and topical (including intranasal, inhalation and eye administration) use of corticosteroids. If you experience symptoms such as blurred vision or other visual disturbances, consideration should be given to referring you to an ophthalmologist to determine possible causes of visual impairment, which may include cataracts, glaucoma or rare diseases such as Central Serous Chorioretinopathy (CSCR), which have been reported following systemic and topical corticosteroid use."
