Any order is fine: Just wait about three minutes between simultaneous drops keeping eyes gently closed and pressing on the inside corner of the eye to the nose bone.

No: The order does not matter. If all drops are to be taken at the same time of day, make nature you wait a little between drops to ensure they don't rinse each other out.

Yes: Your treating md will advise you, but a common practice is to use your cosopt™ and alphagan™ twice per day. You should wait at least 5' between eye drop instillation and also apply pressure to the inner corner of your eyelid for one minute. A twice/day regimen is ideally 12 hrs apart. Also, it does not matter the order. Xalatan™ is instilled generally close to bedtime by the same technique.

No: There is no best order in which to administer these three eye drops. It is important to wait at least 5 minutes between each medication and it is best practice to close your eye and press on the inner corner of the eye for 1 minute after administration to ensure the medication is absorbed.
