Ophthalmologist in the room!
I deal with this all the time - patients young & old have this problem.
Of the artificial tears on the market, Systane seems to be one of the best. It does sometimes cause a 10 second blur, because the drop turns gel-like when it mixes with tears. Another drop that some swear by is Soothe - it's an oil-drop, so it causes a haze for a few minutes, but it can last a while.
If the dry eye causes a constant burn or inflammation, I might consider using a mild steroid, such as Alrex. It's an anti-inflammatory which soothes the eye and attacks any inflammatory component that may cause dry eye.
Alot of dry eye is caused by tear insufficiency - the eyes don't make enough tears. In this situation, punctum plugs may help. It basically stops or slows the tears from draining int the nose, so the tears (and drops) lasts in the eye longer. It's not a surgical procedure - it's done in the office. It comes in temporary form (melts away in 1-2 weeks) and permanent form (stays until its removed or falls out).I usually offer the temporary/collagen kind and tell the patient to return in 2 weeks to report if they felt a difference. If it was a success, they get the permanent/silicone kind.
Other kinds of dry eye is caused by tear dysfunction - there are alot of tears, but they don't work the way they should (evaporate too quickly, run down the face, etc.). Here Restasis helps people the most. For many, Restasis is a miracle drug. Just keep in mind, it may take using the drop twice every day for up to three months to see if it works; it doesn't work right away. I usually give another drop to take with it while the restasis takes its time to work.
Also, make sure your eye MD checks for other things that may cause dry eye (such as blepharitis or allergies) - many times treating the cause helps the most.
