What Diclofenac PF is used for

Diclofenac PF eye drops are prescribed by ophthalmologists at Pristine Eye Hospitals to help manage specific eye conditions. It is an anti-inflammatory medicine that belongs to a category called NSAIDs (Non-Steroidal Anti-inflammatory Drugs).

Reducing inflammation after eye surgery: After certain eye operations, it’s common for the eye to experience some inflammation. Diclofenac PF helps to calm this response, promoting comfort and healing.
Relieving pain from corneal abrasions: A corneal abrasion is a scratch or injury to the clear front surface of your eye (the cornea). This can be quite painful, and Diclofenac PF helps to alleviate this discomfort.

The ‘PF’ in Diclofenac PF stands for ‘Preservative-Free’. This formulation is particularly beneficial for sensitive eye surfaces, as preservatives found in some eye drops can sometimes cause irritation.

How it works

Diclofenac PF works as a topical NSAID (Non-Steroidal Anti-inflammatory Drug). When applied as an eye drop, it acts locally on the eye to reduce inflammation and pain. Inflammation is a natural response of the body to injury or irritation, but excessive inflammation can cause discomfort and slow healing. NSAIDs like Diclofenac PF work by blocking certain substances in the body that contribute to inflammation and pain. By doing so, it helps to soothe the eye, reduce swelling, and alleviate pain, especially after surgery or an injury like a corneal abrasion. The preservative-free nature of this formulation means it is gentler on the delicate surface of the eye, making it suitable for conditions where the eye’s surface might be particularly sensitive.

How it’s used

Using eye drops correctly is very important to ensure the medicine works effectively and to prevent contamination. Always follow your ophthalmologist’s specific instructions for Diclofenac PF. Here are the general guidelines for its use:

Dosing: The typical dosage for Diclofenac PF eye drops is 1 drop instilled into the affected eye four times a day. However, your doctor will tell you the exact schedule based on your condition.
Preparation: Before using the eye drops, always wash your hands thoroughly with soap and water.
Application: Gently pull down your lower eyelid to create a small pocket. Hold the unit-dose container upside down, directly over your eye. Squeeze the container gently to release one drop into the pocket. Try not to touch your eye or eyelid with the tip of the dropper to avoid contamination.
After application: Close your eye gently for a minute or two. Do not blink excessively. This helps the medicine to be absorbed properly.
Unit-dose container: Diclofenac PF comes in preservative-free unit-dose containers. This means each small container is for single use. After applying the drop, discard the remaining solution and the container, even if there is some liquid left. Do not save it for later use.
Missed dose: If you miss a dose, apply it as soon as you remember, unless it is almost time for your next dose. In that case, skip the missed dose and continue with your regular schedule. Do not double the dose to make up for a missed one.
Consistency: Use the eye drops regularly as prescribed by your doctor, even if your symptoms improve. Stopping the medication too early might lead to a return of inflammation or pain.

If you are using other eye drops, wait at least 5-10 minutes between applying different types of drops to allow each medicine to be absorbed properly.

Always follow your ophthalmologist’s exact instructions.

Precautions & side effects

While Diclofenac PF is generally well-tolerated, it’s important to be aware of certain precautions and potential considerations:

Understanding Eye Inflammation and Corneal Abrasions

Our eyes are incredibly delicate and vital organs. Sometimes, due to surgery or injury, they can become inflamed or painful. Inflammation is the body’s natural response to injury or irritation, characterized by redness, swelling, warmth, and sometimes pain. While this response is part of the healing process, excessive inflammation can cause significant discomfort and, in some cases, hinder recovery. For instance, after eye surgery, some degree of inflammation is expected. Medicines like Diclofenac PF are used to manage this inflammation, helping to keep you comfortable and support the healing process.

A corneal abrasion is essentially a scratch on the cornea, which is the clear, dome-shaped front surface of your eye. The cornea plays a crucial role in focusing light onto the retina, allowing us to see clearly. Because it’s exposed, the cornea is susceptible to injuries from dust, sand, fingernails, or even improper contact lens use. A corneal abrasion can be very painful, feeling like something is constantly in your eye, and may cause light sensitivity, redness, and watery eyes. Prompt and appropriate treatment, which may include pain-relieving eye drops like Diclofenac PF, is important to alleviate discomfort and prevent complications.

Correct Eye Drop Instillation and Hygiene

Using eye drops correctly is crucial for their effectiveness and to prevent infection. Here’s a step-by-step guide to help you:

Wash Your Hands: Always start by washing your hands thoroughly with soap and water. This is the most important step to prevent introducing germs into your eye.
Prepare the Drop: If using a unit-dose container (like Diclofenac PF), twist off the cap. Make sure the tip of the container does not touch any surface.
Position Yourself: You can either lie down or tilt your head back while looking up.
Create a Pocket: Gently pull down your lower eyelid with one finger to create a small pocket between your eye and the eyelid.
Instil the Drop: Hold the unit-dose container directly over your eye, about an inch away. Squeeze gently to release one drop into the pocket. Try your best not to let the tip of the container touch your eye, eyelid, or eyelashes.
Close Your Eye: After instilling the drop, close your eye gently for 1-2 minutes. Avoid blinking or squeezing your eye tightly, as this can push the medicine out.
Discard: Since Diclofenac PF comes in preservative-free unit-dose containers, discard the container immediately after use, even if there’s solution left. Each container is for single use only.
Repeat (if necessary): If you need to apply drops to both eyes, repeat the process for the other eye. If you are using multiple types of eye drops, wait at least 5-10 minutes between different medications to ensure each drop has enough time to be absorbed.

Maintaining good eye hygiene is also vital. Avoid rubbing your eyes, especially if you have an active infection or injury. Use clean tissues to dab away any excess liquid around your eyes. Never share your eye drops with anyone else, as this can spread infections.

When to Seek Medical Help

While Diclofenac PF is prescribed to help your eyes heal and reduce discomfort, it’s important to know when to contact your ophthalmologist. Your eye health is paramount, and any concerning symptoms should be addressed promptly. You should immediately contact Pristine Eye Hospitals or your ophthalmologist if you experience any of the following:

Worsening Pain or Discomfort: If your eye pain or discomfort increases or does not improve after using the drops as prescribed.
Increased Redness or Swelling: If the redness or swelling in your eye becomes more pronounced.
Changes in Vision: Any sudden decrease in vision, blurred vision, or new visual disturbances.
Discharge: If you notice any new or increased discharge from your eye, especially if it’s thick, yellow, or green.
Light Sensitivity: If you develop severe sensitivity to light that was not present before or worsens.
Allergic Reaction: Signs of an allergic reaction, such as a rash, itching, severe swelling around the eye, or difficulty breathing (though rare with topical drops, always be vigilant).
New Symptoms: Any new or unusual symptoms related to your eye that concern you.

Remember, your ophthalmologist is your best resource for any questions or concerns about your eye condition and treatment. Always follow their advice and attend any scheduled follow-up appointments to ensure your eyes are healing properly.
