Follow the label and the demonstration

Key points
This page teaches technique after a prescription — not a pitch to buy drops.
Timing, order, storage and in-use life follow the label and the doctor.
Missed drops can destabilise pressure control — one improvable factor, not the only one.
Glaucoma drop classes and lubricant ingredients are on related pages.
Education after a prescription, not a product pitch. Missed doses can make pressure control less stable — one factor among others, not the only cause.
Wash hands. Shake if that product’s label says so.
Tilt the head; pull down the lower lid to make a pocket.
Do not let the tip touch the eye or lashes. How much to instil follows the demonstration.
Close gently; do not squeeze-blink.
Whether to press the inner corner, how long to wait between drops, and how long a bottle keeps after opening: follow that product’s label and the doctor. This page is not your regimen.
This is general medical information, not a diagnosis, and cannot replace an in-person consultation with a registered ophthalmologist, refraction, or a dilated fundus exam. It is not advice to use any medicine or undergo any procedure. Medicines (including off-label use), laser or surgery must be decided by a registered doctor after examination, according to indications and Hong Kong registration. Figures from the literature are published averages, not any clinic’s results. This site does not book, prescribe or refer. Do not change treatment on your own.
