Why is the flow of irrigational fluid directed from the inner canthus to the outer canthus?

The flow of irrigational fluid directed from the inner canthus to the outer canthus promotes consistency in treatment by facilitating a uniform distribution of the irrigating solution across the eye's surface. This method helps ensure that the entirety of the corneal area is adequately cleansed, reducing the risk of any debris or contaminants remaining in the eye.

This directed flow also helps in effectively washing away any foreign materials or irritants without causing excessive discomfort or disruption to the patient's vision. By following this established practice, healthcare providers can ensure that patients receive consistent and effective care during procedures that involve eye irrigation.
