Errors of Refraction Among Primary School Children

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

Clinical Trial Summary

This study will include primary school children to evalute their refraction and follow those who will wear glasses to detect their compliance. Visual acuity will be measured using autorefractometer after cycloplegic eye drops 3 times and glasses will be prescribed for those who are needed. Follow up of the students to detect their compliance of wearing correction.
