Two Topical (diluted betadine and artificial tears) or (betamethasone and chloramphenicol) versus placebo (two drops of artificial tears) interventions to control clinical symptoms and complications of epidemic keratoconjunctivitis 2025-06-22 anticipated 69 Complete https://irct.ir/trial/83530 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Treatment, Randomization description: The randomization type is simple randomization. Using a random number table, participants will be assigned to groups until the target sample size in each group is reached, Blinding description: Allocation concealment will be implemented using opaque, sealed, sequentially numbered envelopes. The procedure will be as follows: A random sequence is first generated. The allocation sequence is recorded on separate cards. Each card is placed inside an envelope in sequential order. The envelopes are numbered externally and stored in a box in sequential order. Upon enrollment, participants will select an envelope in the order of their recruitment, thereby revealing their assigned intervention group. 3 Epidemic keratoconjunctivitis.
