      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Not used, Assignment: Parallel, Purpose: Treatment, Randomization description: In this study, the block randomization method is used and the block size is 6. The website https://www.sealedenvelope.com is used to generate random sequences. Each participant is assigned a sequence. Then, each participant was randomly assigned to one of the arms of the study (A or B). The random sequence is given to the epidemiologist of the study, and every patient who enters the study, the doctor will contact him to find out whether the person will enter group A or B, Blinding description: After random allocation, the randomized list will be placed in sealed envelopes. In this way, the first doctor will be blinded to assigning people to treatment groups. Regarding to ophthalmologist does not know about the treatments provided, he will be blind.</study_design>
