Eye drops, used in the treatment of glaucoma work by reducing the intraocular pressure (IOP) within your eyes. Increased eye pressure is a major risk factor for optic nerve damage.
Eye drops are the most common form of treatment for glaucoma. Since glaucoma often has no symptoms, people may be tempted to stop taking, or may forget to take their medication/eye drops. It is important that you follow your treatment plan and appointments, as recommended by your eye care practitioner. This is because glaucoma is a life-long, often progressive condition, and appropriate treatment can prevent vision loss.
Eye drops work in two ways to reduce eye pressure:
- They reduce the amount of aqueous fluid secreted into the eye, or
- Help increase the outflow of aqueous fluid from the drainage angle.
Approximately one half of patients don’t take their glaucoma medication as prescribed, increasing the amount of visual loss caused by glaucoma.
- Before instilling your eye dropsShow lessShow more
- Always check the label on your eye drop container before instilling your drops. Make sure they have not expired.
- Make sure you have the correct eye drop and it is the correct time of day to instil it.
- If you wear contact lenses — remove them at least 15 minutes beforehand. You can then replace your contact lenses 15 minutes after the drops have been instilled.
- Keep handy a couple of clean tissues.
- Wash your hands. Carefully remove the cap of the eye drop container, ensuring the tip of the container doesn’t touch anything to reduce risk of contamination and infection. Place the cap on a clean tissue.

You can choose to carry out the next steps standing up, sitting down or lying down.
Note: Most people find it more difficult standing up.
- Tilt your head slightly back. Gently pull down the lower eyelid to form a pocket (or pouch).
- With the other hand, hold the bottle upside down above the eye – aiming for the pocket created by the lower lid. You may want to rest that hand on your forehead to keep your hand steady.
- Gently squeeze the container. Try to allow only one drop to fall onto the inside of the lower eyelid.
- Gently release the lower lid and close your eye.
- Press the tip of your finger against the inside corner of the closed eye, applying gentle pressure over the drainage canal opening and hold for at least two minutes to stop the eye drops from draining down to the nose and throat.
- Gently wipe off any excess medication that may have spilt onto your face with a clean tissue.
- Repeat steps 1 to 6 if you need to instil an eye drop in the opposite eye.
- If you have a number of different eye drops to administer, leave at least 5 minutes between each different drop.
- What can I do to make sure my eye drops work effectively?Show lessShow more
- It is very important to use your eye drops every day as instructed by your eye care practitioner.
- Try to use your eye drops at the same time each day. Set an alarm on your smart phone or watch to remind yourself to instil your drops at the correct times each day.
- Make sure the eye drops are instilled in the correct eye.
- Only administer one drop at a time.
- If you miss a dose of your eye drops, use it as soon as you remember.
- DO NOT instil extra drops to make up for the missing dose.
- Remember to get a new script for your eye drops if you know you are about to run out of the current ones. Your GP can also prescribe the drops for you if you don't have an appointment with your ophthalmologist.
- If you have difficulty instilling your eye drops, consider asking someone else to instil them for you. Or contact Glaucoma Australia to check if there is a Dose Administration Aid available to assist you.
