Expert advice for Endor Eye Drop
Endor helps lower high pressure in the eye and reduces the risk of vision loss. For best results, put one drop 2-3 times daily in the affected eye(s). Apply pressure on the corner of the eye (close to the nose) for about 1 minute, immediately after instilling the drop. This minimizes the risk of side effects. Take care to prevent contact of eye dispenser with eye, eyelid, eyelashes, or finger to avoid infection. Remove contact lenses before using Betagan and allow at least 15 minutes before re-inserting them. When applying multiple eye medications, wait for at least 5-15 minutes before delivering the next medication in the same eye to avoid dilution.
