Nevanac (active ingredient: nepafenac) is a prescription ophthalmic medication used to reduce pain and inflammation in the eye, particularly after cataract surgery.
It belongs to a group of medications called nonsteroidal anti-inflammatory drugs (NSAIDs). Unlike oral NSAIDs, Nevanac is applied directly to the eye, allowing it to work locally where inflammation is occurring.
Cataract Surgery
Nevanac is commonly prescribed to help manage pain and inflammation associated with cataract surgery.
A cataract develops when the natural lens of the eye becomes cloudy. During cataract surgery, the cloudy lens is removed and usually replaced with an artificial intraocular lens.
After surgery, the eye may become inflamed as part of the normal healing process. This inflammation can lead to symptoms such as:
- Eye discomfort or pain
- Redness
- Swelling
- Irritation
- Sensitivity around the treated eye
Nevanac helps control this postoperative inflammation and may make the recovery period more comfortable.
Why Inflammation Occurs After Cataract Surgery
Any surgical procedure can trigger the body’s inflammatory response.
During cataract surgery, tissues inside the eye are manipulated, which can cause the release of inflammatory chemicals. One important group of these chemicals is called prostaglandins.
Prostaglandins can contribute to:
- Pain
- Swelling
- Redness
- Increased sensitivity
- Inflammation inside the eye
By reducing prostaglandin production, Nevanac helps limit these inflammatory effects.
How Nevanac Works
Nepafenac is a prodrug, which means it is converted inside the eye into its active form, called amfenac.
Amfenac blocks enzymes known as cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX-2). These enzymes help the body produce prostaglandins.
When COX activity is reduced:
- Fewer prostaglandins are produced
- Inflammation decreases
- Swelling may improve
- Eye pain may be reduced
This is how Nevanac helps control inflammation after eye surgery.
How Nevanac Reaches the Eye
Nevanac is applied directly to the surface of the eye as an ophthalmic suspension.
After the drops are placed in the eye, nepafenac passes through the cornea and enters the surrounding eye tissues. It is then converted into amfenac, the active anti-inflammatory compound.
This local delivery allows the medication to target inflammation in the eye while limiting unnecessary exposure to the rest of the body.
What Symptoms Can Nevanac Help Reduce?
Nevanac may help relieve several symptoms that can occur after cataract surgery, including:
- Eye pain
- Tenderness
- Swelling
- Redness
- General postoperative inflammation
Not every patient will experience the same symptoms or level of improvement. Your healthcare provider will determine how long you should use Nevanac based on your surgery and recovery.
When Is Nevanac Usually Used?
Nevanac is generally prescribed around the time of cataract surgery.
Your healthcare provider may instruct you to begin using the eye drops before surgery and continue them for a certain period afterward.
The exact schedule can vary, so it is important to follow the dosing instructions provided by your ophthalmologist.
Nevanac and Diabetic Patients
Some patients with diabetes may be at greater risk of developing swelling in the central part of the retina after cataract surgery.
Depending on the specific Nevanac formulation and your medical history, your eye specialist may prescribe nepafenac to help reduce postoperative inflammation and related complications.
Patients with diabetes may require closer eye monitoring after surgery.
How Nevanac Differs From Steroid Eye Drops
Nevanac is an NSAID eye drop, while some other medications used after cataract surgery are corticosteroid eye drops.
Both can reduce inflammation, but they work through different mechanisms.
Nevanac mainly works by reducing prostaglandin production, while corticosteroids affect a broader range of inflammatory pathways.
In some cases, an ophthalmologist may prescribe both types of medication together depending on the patient’s needs.
Importance of Using Nevanac as Prescribed
Use Nevanac exactly as directed by your healthcare provider.
Do not use more drops, use the medication more often, or continue treatment longer than prescribed unless your eye specialist tells you to do so.
Using ophthalmic NSAIDs for longer than recommended may increase the risk of certain eye complications, so follow-up appointments are important during recovery.
