Who should remove any object that has penetrated the eyeball?

The correct answer is that only a doctor should remove any object that has penetrated the eyeball. This is because the eye is a highly sensitive and complex organ, and the risk of further injury or complications is significant when a foreign object is involved. A medical professional, especially a doctor, possesses the necessary training and expertise to assess the situation accurately and to perform any necessary interventions safely.

Attempting to remove an object from the eyeball can lead to more damage, increase the risk of infection, or result in loss of vision. Medical professionals are trained to use specific techniques and instruments that minimize these risks. Thus, only a doctor should undertake such a procedure to ensure the best possible outcome for the patient.
