Precision Application: How much eye ointment do I put in?

4 min read

Prescription errors in ophthalmology can occur in up to 8% of cases, highlighting the need for proper administration techniques [1.6.3, 1.6.6]. Knowing exactly how much eye ointment to put in is crucial for safety and effectiveness, as using incorrect amounts can harm your eyes [1.9.2].

Quick Summary

Apply a thin ribbon of eye ointment, typically about 1 cm (or 1/3 to 1/2 inch), into the pocket of the lower eyelid [1.2.1, 1.2.4]. This ensures the medication treats the eye effectively without causing excessive blurriness.

Key Points

  • Dosage: Apply a thin ribbon of ointment about 1 cm (1/3 to 1/2 inch) long.

  • Application Site: Squeeze the ointment into the small pocket created by gently pulling down the lower eyelid.

  • Hygiene is Critical: Always wash your hands before and after, and never let the tube's tip touch any surface, including your eye.

  • Drops First: If using both eye drops and ointment, apply the drops first and wait 5-10 minutes before the ointment.

  • Expect Blurry Vision: It's normal for vision to be blurry for a few minutes after application; this is why it's often recommended for bedtime use.

  • Don't Overuse: Using more ointment than prescribed will not increase effectiveness and can be harmful.

  • Avoid Contamination: Never share eye medication, and discard it as recommended (often 28 days after opening for prescriptions).

Understanding Eye Ointment

Eye ointments are semi-solid, greasy medications used to treat a variety of eye conditions, including infections like conjunctivitis (pink eye), dry eye syndrome, and styes [1.5.6]. Unlike liquid eye drops that can be quickly washed away by tears, ointments have a thicker consistency [1.5.3]. This allows them to remain on the surface of the eye for an extended period, providing a protective barrier and delivering medication continuously [1.5.1, 1.5.3]. This long-lasting effect makes them particularly suitable for overnight use or for more severe conditions that require prolonged medication contact [1.5.1, 1.5.2]. However, this thickness is also why ointments often cause temporary blurred vision immediately after application [1.8.2, 1.9.1].

The Correct Amount: How Much Eye Ointment Do I Put In?

The most common recommendation is to apply a thin strip or ribbon of ointment about 1 centimeter (roughly 1/3 to 1/2 inch) long [1.2.1, 1.2.4, 1.7.3]. Some sources describe this amount as being similar to the size of a grain of rice [1.2.3]. It is crucial not to use more ointment than directed by your doctor, as this can be counterproductive and potentially harmful [1.9.2]. The goal is to apply enough medication to coat the eye as you blink without using an excessive amount that causes significant, prolonged vision obstruction [1.2.4, 1.9.1]. If you are using both eye drops and an ointment, always apply the eye drops first, wait 5 to 10 minutes, and then apply the ointment [1.2.6, 1.4.1]. This prevents the ointment from blocking the absorption of the drops [1.5.3].

Step-by-Step Application Guide

Proper application ensures the medication is effective and prevents contamination.

  1. Wash Your Hands: Thoroughly wash your hands with soap and water to prevent transferring bacteria to your eye [1.2.3, 1.3.1].
  2. Warm the Tube: Holding the tube in your hand for a few minutes can warm the ointment, helping it flow more easily [1.2.3, 1.2.6].
  3. Prepare for Application: Remove the cap and be careful not to touch the applicator tip to any surface, including your fingers or eye [1.2.1, 1.4.1]. If it's the first time using the tube, you may need to discard the first quarter-inch of ointment as it might be dry [1.2.6].
  4. Position Yourself: Tilt your head back and look up toward the ceiling [1.2.3].
  5. Create a Pocket: Use one finger to gently pull your lower eyelid down, away from the eyeball. This creates a small space or 'pocket' [1.2.1, 1.4.3].
  6. Apply the Ointment: Bring the tube close to your eye (about an inch away) and squeeze a thin 1 cm ribbon of ointment into the lower eyelid pocket you've created [1.2.3, 1.2.6]. Avoid touching the tube's tip to your eye, eyelid, or lashes [1.4.1].
  7. Release and Close: Let go of the lower eyelid. Gently close your eye for 1 to 2 minutes to allow the ointment to melt and spread across the eye's surface [1.2.1, 1.3.1]. You can roll your eyeball around to help distribute the medication [1.2.6].
  8. Clean Up: Wipe any excess ointment from around your eye with a clean tissue. Wipe the tip of the tube with a separate clean tissue before tightly replacing the cap [1.2.1, 1.3.1]. Wash your hands again [1.3.1].

Eye Ointments vs. Eye Drops

Choosing between eye drops and ointments depends on the condition, severity, and lifestyle needs [1.5.1].

Feature Eye Drops Eye Ointment
Consistency Liquid, watery [1.5.1] Semi-solid, thick, greasy [1.5.3, 1.5.6]
Application Dropped into the eye [1.5.1] Applied as a ribbon into the lower eyelid [1.2.4]
Vision Effect Minimal to no blurred vision [1.5.3] Causes temporary blurred vision [1.5.3, 1.8.2]
Duration of Action Shorter, may require frequent application [1.5.3] Long-lasting, ideal for overnight use [1.5.1, 1.5.3]
Best For Mild to moderate dry eye, daytime use [1.5.1, 1.5.5] Severe dry eye, infections, post-surgery care, nighttime relief [1.5.2, 1.5.5]

Special Considerations

Applying to a Child

When administering eye ointment to a child, it can be helpful to have them lie down [1.7.2]. You may need another adult to help hold the child still, or you can wrap a baby in a blanket to keep their arms from interfering [1.7.3, 1.7.4]. Gently pull the lower lid down to create the pocket and apply the thin strip of ointment [1.7.2]. Asking the child to close their eyes and move their eyeball around helps spread the medicine [1.7.1].

Common Mistakes to Avoid

  • Contaminating the Tube: Never let the tip of the ointment tube touch your eye, eyelid, or any other surface [1.2.1, 1.4.1]. This can introduce bacteria and lead to infection.
  • Using Too Much: Do not use larger amounts than prescribed by your doctor. It won't improve the effect and can harm your eyes [1.9.2].
  • Applying with a Finger: Do not squeeze ointment onto your finger to apply it, as this can transfer bacteria and risk scratching the cornea [1.2.3, 1.9.1].
  • Sharing Medication: Never use someone else's eye ointment [1.4.1].
  • Improper Order: If using both drops and ointment, always use drops first and wait several minutes before applying the ointment [1.4.1].

Conclusion

Mastering the correct technique for applying eye ointment is essential for treating your eye condition safely and effectively. The key is to use a small, clean, and precise amount—a 1 cm ribbon—applied directly into the pocket of the lower eyelid without contaminating the tube. By following these steps and avoiding common mistakes, you ensure the medication works as intended while minimizing risks. Always follow your doctor's specific instructions and consult them if you experience worsening symptoms or side effects like pain, severe irritation, or vision changes [1.8.1, 1.8.4].

Frequently Asked Questions

A thin strip of eye ointment is generally considered to be about 1 centimeter, which is roughly 1/3 to 1/2 of an inch long, or the size of a grain of rice [1.2.1, 1.2.3, 1.2.4].

Yes, you should only use the amount of ointment as directed by your doctor. Using larger amounts can be harmful to your eyes and will likely cause more significant and prolonged blurry vision [1.9.1, 1.9.2].

Temporary blurred vision is a common and normal side effect of eye ointment due to its thick, greasy consistency. This is why many healthcare providers recommend applying it at bedtime [1.5.1, 1.8.2].

If the tip of the tube touches your eye, eyelid, or any other surface, it can become contaminated with bacteria. To be safe, you should contact your pharmacy to arrange for a replacement tube [1.2.5, 1.4.1].

If you are prescribed both, you should always apply the eye drops first. Wait for 5 to 10 minutes to allow the drops to be absorbed before applying the eye ointment [1.2.6, 1.4.1].

Have the child lie down, gently pull their lower eyelid to form a pocket, and apply a thin 1 cm strip of ointment inside. It may help to have another adult assist or to wrap a small child in a blanket to keep them still [1.7.2, 1.7.3].

Common side effects include temporary blurred vision, mild stinging or burning, itching, and redness [1.8.2]. If you experience severe side effects like eye pain, worsening irritation, or signs of an allergic reaction, contact your doctor immediately [1.8.1].
