Final answer:
The correct technique for instilling eye drops involves placing the medication into the conjunctival sac, the space between the lower eyelid and the eye's surface.
Step-by-step explanation:
When instilling eye drops, the proper technique involves instilling the medication into the conjunctival sac. This is the small gap between the inside of the eyelid and the surface of the eye. To do this, the patient should tilt their head back and look up. While pulling down on the lower lid to create a small pocket, the medication can be dropped into this space without touching the eye with the dropper. It's important not to touch the dropper to the eye or eyelids to avoid contamination and to administer the correct number of drops as prescribed by a healthcare professional.
