How PROLENSA Works: The Science of Pain Relief
PROLENSA (bromfenac ophthalmic solution) is a nonsteroidal anti-inflammatory drug (NSAID) used topically in the eye. Post-cataract surgery, eyes can become inflamed due to tissue trauma, leading to pain and swelling caused by prostaglandins.
The active ingredient, bromfenac, inhibits cyclooxygenase (COX) enzymes (COX-1 and COX-2), which are necessary for prostaglandin production. By blocking these enzymes, PROLENSA stops the inflammatory process and reduces prostaglandins in ocular tissues. This approach offers localized pain and inflammation relief with less systemic exposure than oral NSAIDs.
Therapeutic Benefits After Cataract Surgery
PROLENSA helps manage inflammation, leading to:
- Reduction of Inflammation: It has been shown to significantly decrease anterior chamber inflammation after surgery.
- Pain Reduction: PROLENSA effectively reduces eye pain, promoting a more comfortable recovery.
- Symptom Management: It alleviates symptoms like redness, irritation, and light sensitivity.
Using PROLENSA Safely and Effectively
Your doctor will provide specific usage instructions. A typical regimen is one drop daily in the affected eye, starting a day before surgery and continuing for 14 days afterward. Proper administration is key.
Step-by-Step Administration Guide
- Wash hands thoroughly.
- Gently shake the bottle.
- Tilt head back and pull down the lower eyelid to form a pocket.
- Administer one drop into the pocket without touching the eye.
- Close the eye for one to two minutes; avoid blinking or squeezing.
- Press the tear duct in the inner corner of the eye gently.
- Remove contact lenses before use and wait at least 10 minutes before reinserting.
- If using other eye drops, wait at least five minutes between medications.
Potential Side Effects and Risks
PROLENSA is usually well-tolerated, but side effects can occur. Common ones (3% to 8% of patients) include anterior chamber inflammation, foreign body sensation, eye pain, blurred vision, and light sensitivity.
Rare but more serious side effects may occur, especially with extended use or in high-risk individuals:
- Corneal Reactions: Prolonged NSAID use can lead to keratitis, thinning, erosion, ulceration, or perforation of the cornea. Risks are higher for patients with diabetes, dry eyes, or complex surgeries.
- Delayed Healing: NSAIDs might slow healing, particularly when used with topical corticosteroids.
- Allergic Reactions: PROLENSA contains sodium sulfite, which can trigger allergic responses in sensitive people, including asthmatics.
- Increased Bleeding Risk: Ocular NSAIDs can increase bleeding risk in eye tissues, caution is advised for those with bleeding tendencies or on blood thinners.
Comparing PROLENSA to Other NSAID Eye Drops
Other NSAID eye drops are used post-cataract surgery, such as nepafenac (Nevanac). Here is a comparison:
Feature | PROLENSA (Bromfenac) | Nevanac (Nepafenac) |
---|---|---|
Dosing Frequency | Once daily, often for 14 days | Typically three times daily, for up to 14 days |
Active Ingredient | Bromfenac (0.07%) | Nepafenac (0.1%) |
Target Population | Adults only | Adults and children age 10 and older |
Side Effects | Blurred vision, light sensitivity, foreign body sensation, eye pain | Decreased visual clarity, feeling something in the eye |
Special Consideration | Contains sodium sulfite (potential allergen) | Does not contain sulfites, approved for a broader age range |
pH | Closer to neutral tears (7.8) | Less neutral |

Conclusion
In conclusion, what does PROLENSA do to your eyes? It provides localized pain and inflammation relief after cataract surgery by inhibiting prostaglandin production via its active ingredient, bromfenac. This helps reduce discomfort and other symptoms, aiding recovery. Proper use and awareness of potential side effects, particularly concerning the cornea and allergic reactions, are vital. Always follow your ophthalmologist's guidance and report any unusual symptoms for a successful recovery. PROLENSA's efficacy and once-daily dosing make it a valuable option in ophthalmic care.
