Acute Conjunctivitis: Is Your Eye Drops Treatment Working? - Ophthalmology

Issues related to conjunctivitis?


Hello: I previously experienced severe itching in my eyes and visited an ophthalmologist.
The doctor diagnosed me with acute conjunctivitis and prescribed two bottles of eye drops for treatment, one of which is "Kedron." After applying it, my eyes started to sting, and I even had difficulty keeping them open.
Is the stinging sensation a sign that the medication is working and treating the condition? I'm hesitant about whether to continue using it.
Thank you for your help!

More Info


Acute conjunctivitis, commonly known as pink eye, is an inflammation of the conjunctiva, the thin membrane that covers the white part of the eye and the inner eyelids. It can be caused by various factors, including viral infections, bacterial infections, allergens, or irritants. When you experience symptoms such as itching, redness, and tearing, it is essential to seek medical attention, as you did.

In your case, the doctor prescribed two types of eye drops, one of which is "Kedalon." It's not uncommon for patients to experience a stinging or burning sensation upon instilling certain eye drops. This sensation can be attributed to several factors:
1. pH Level: The pH level of the eye drops may differ from that of your natural tears, leading to temporary discomfort.

2. Preservatives: Some eye drops contain preservatives that can irritate the eye, especially if used frequently.

3. Active Ingredients: Certain medications, particularly those that are anti-inflammatory or antibacterial, may cause a stinging sensation as they work to reduce inflammation or fight infection.

The discomfort you are experiencing does not necessarily indicate that the treatment is ineffective. In fact, it may be a sign that the medication is actively working. However, if the stinging sensation is severe or persists, it is essential to consult your eye care provider. They may recommend an alternative medication that is less irritating or suggest ways to alleviate the discomfort.

Regarding your hesitation to continue using the drops, it is crucial to follow your doctor's instructions unless advised otherwise. Stopping treatment prematurely could lead to a prolonged infection or complications. If you find the discomfort unbearable, contact your healthcare provider to discuss your symptoms and explore alternative treatment options.

In addition to using prescribed eye drops, here are some general tips to manage acute conjunctivitis:
- Maintain Hygiene: Wash your hands frequently and avoid touching your eyes to prevent further irritation or spreading the infection.

- Cold Compress: Applying a clean, cold compress over your eyes can help reduce swelling and soothe irritation.

- Artificial Tears: If dryness is a concern, using preservative-free artificial tears can provide relief without additional irritation.

- Avoid Contact Lenses: If you wear contact lenses, it's best to avoid them until your symptoms resolve completely.

Lastly, if you notice any worsening of symptoms, such as increased redness, swelling, or discharge, or if your vision becomes affected, seek immediate medical attention. Your eye health is paramount, and timely intervention can prevent complications.

In summary, while the stinging sensation from the eye drops can be uncomfortable, it does not necessarily mean the treatment is ineffective. Continue to follow your doctor's advice, maintain good eye hygiene, and reach out to your healthcare provider if you have concerns about your treatment or symptoms.
