Risks of Using Expired Artificial Tears: What You Need to Know - Ophthalmology

More Info

Using expired artificial tears can pose several risks to your eye health, especially when you are wearing contact lenses like orthokeratology lenses. While it may seem that the artificial tears appear clear and without any visible contamination, the expiration date is there for a reason. Here’s a detailed explanation of the potential risks and what you should do next.


Risks of Using Expired Artificial Tears
1. Reduced Efficacy: Over time, the active ingredients in artificial tears can degrade, leading to reduced effectiveness. This means that the product may not provide the moisture and lubrication your eyes need, which is particularly important when wearing contact lenses.

2. Increased Risk of Infection: Expired products can harbor bacteria or other pathogens, especially if the bottle has been opened. Using these tears can introduce harmful microorganisms into your eyes, increasing the risk of infections such as conjunctivitis or keratitis.

3. Allergic Reactions: As artificial tears age, the preservatives and other components may change chemically, potentially leading to allergic reactions or irritation. Symptoms can include redness, itching, and discomfort, which you are currently experiencing.

4. Eye Irritation: The preservatives in artificial tears can become irritating over time. If the tears are expired, they may cause more irritation than fresh, properly stored tears. This can lead to symptoms like redness, itching, and a sensation of grittiness in the eyes.


Symptoms You Are Experiencing
The symptoms you describe—discomfort, redness, and itching—are concerning, especially since you used an expired product. These symptoms could indicate irritation from the expired tears or an allergic reaction to the preservatives or other components. Additionally, if you are wearing contact lenses, any irritation can be exacerbated by the lenses themselves, leading to further discomfort.


What to Do Next
1. Stop Using the Expired Product: Discontinue the use of the expired artificial tears immediately. Do not use any other expired eye products.

2. Rinse Your Eyes: If you feel discomfort, you can rinse your eyes with sterile saline solution or artificial tears that are within their expiration date. This can help flush out any irritants.

3. Monitor Your Symptoms: Keep an eye on your symptoms. If they persist or worsen, it’s important to seek medical attention.

4. Consult an Eye Care Professional: Given your symptoms and the use of expired artificial tears, it’s advisable to consult with an eye care professional. They can assess your eyes for any signs of infection or irritation and provide appropriate treatment.

5. Avoid Contact Lenses Until Cleared: If you are experiencing discomfort, it may be best to avoid wearing your contact lenses until your symptoms resolve and you have consulted with a professional.


Conclusion
Using expired artificial tears can lead to various complications, especially when wearing contact lenses. Your symptoms of discomfort, redness, and itching warrant immediate attention. It’s crucial to prioritize your eye health and consult with an eye care professional to ensure that there are no underlying issues and to receive appropriate treatment. Always check the expiration dates on eye care products and avoid using anything that has expired to maintain optimal eye health.
