Expert advice for Laprost Eye Drop
Laprost helps lower high pressure in the eye and reduces the risk of vision loss. For best results, put one drop once a day in the evening/night in the affected eye(s). Laprost may cause brown pigmentation of the iris which may be permanent. You may notice eyelid skin darkening and an increase in the length, thickness, and number of your eyelashes. These changes should disappear after discontinuing Laprost. Take care to prevent contact of eye dispenser with eye, eyelid, eyelashes, or finger to avoid infection. Remove contact lenses before using Laprost 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. Apply pressure on the corner of the eye (close to the nose) for about 1 minute, immediately after instilling the drop so that the medicine does not drain away from the eye.
