This medicine competitively inhibits quinone compound binding to water-soluble protein of the lens and prevents the lens protein degeneration in order to suppress the lens to become cloudy.

It is usually used to slow the progression of early senile cataract.



Early senile cataract



In general, shake the bottle well, and apply 1 to 2 drops at a time, 3 to 5 times a day. Strictly follow the instructions.

Before applying, wash your hands thoroughly with soap and running water. Next, shake the bottle well and open the cap. Then, pull down your lower eyelid lightly and apply the medicine.

Be careful such that the dropper tip does not touch your eyelid, eyelashes, or eye. After applying, keep your eyes closed without blinking for a while (1 to 5 minutes).

Wipe off any excess liquid gently with clean gauze or a tissue. If you need to apply other eye drops at the same time, wait more than 5 minutes.

If you miss a dose, apply the missed dose as soon as possible. If it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. You should not apply two doses at one time.

If you accidentally apply more than your prescribed dose, consult with your doctor or pharmacist.
