Reviews of the drug from ophthalmologists and patients
Reviews from doctors and patients who have undergone ophthalmic surgery allow us to get a more complete picture of eye drops.
Vladimir Ivanovich, 67 years old, Kostroma:
“Nevanac became the third drug prescribed by the ophthalmologist after phacoemulsification of cataracts. I instill it according to the regimen prescribed by the doctor in combination with two other drugs. The result is obvious: there was no inflammation, I am recovering quickly after surgery on both eyes. The bottle is easy to use; the built-in pipette makes it easy to dispense drops.”
Victoria Sergeevna, 56 years old, Voronezh:
“The attending physician prescribed the drug after cataract removal. I was very pleased with the quality of the drops. The operation is relatively painless, but on the first day the pain was quite disturbing. Nevanak successfully helped to cope with this. On the doctor’s recommendation, I used it for three weeks—one bottle was just enough. Before instillation, it is necessary to shake - the suspension gives sediment and becomes very thick. Very convenient pipette with dispenser. The second time the doctor prescribed drops for the treatment of conjunctivitis - they perfectly relieved the burning sensation and reduced tearing. The only drawback is the price, but you can’t save on your health. For the money this is an excellent result.”
The drops relieve itching and burning well.
Anna Ivanovna, ophthalmologist with 38 years of experience:
“Nevanac is usually prescribed before cataract surgery. Treatment continues in the postoperative period according to the scheme determined by the doctor for at least two weeks. The most effective way is the combined use of several medications. In some cases it is effective as an adjuvant. It relieves pain well and eliminates burning sensation. The drops have stood the test of time. In my practice, there have been no complaints about side effects or lack of results.”

Pharmacodynamics and pharmacokinetics
Pharmacodynamics
The active substance is a non-steroidal anti-inflammatory drug with anti-inflammatory and analgesic effects . Penetrates through the cornea and is converted into the active form - amphenac , which inhibits the enzyme necessary for the production of prostaglandins. The use of the drug reduces pain and swelling of the eye tissues without affecting intraocular pressure.
Pharmacokinetics
Rapidly absorbed when applied topically. After daily use, low concentrations of the active substance are detected in the blood after 2 hours. Cmax of nepafenac in the aqueous humor of the eye is observed after 1 hour. The active substance has a high affinity for albumin and binding to them is 99%. Under the influence of enzymes, it undergoes hydrolysis to amfenac, which subsequently forms conjugates with glucuronic acid. In studies after oral administration, it was excreted by the kidneys (about 85%) and through the intestines (6%).
Instructions for use
The drug should be started the day before cataract surgery. You need to apply it 3 times during the day. The dosage is 1 drop in one eye.
Then, at least an hour before surgery, you need to drop another 1 drop into the eyes. After surgery, it must be used for 14 days. Instillation should be carried out three times a day, 1 drop.
It is not recommended to use it for longer than the prescribed period, as it can provoke negative reactions from the cornea. The use of contact lenses during treatment is prohibited. In addition, during therapy you should stay in the sun as little as possible.
Nevanac eye drops should be shaken before use.
