Currently I am in Russia for my mbbs course I have dry eyes symptoms in India opthalmologist suggest me carboxylmethycellusoe 1% eye drop but in Russia it's rare it is used,mostly they prefer systane (Polyethylene Glycol 400, Propylene Glycol, Hydroxypilguar, Boric Acid,
Calcium Chloride, Magnesium Chloride, Potassium Chloride, Sodium Chloride, Zinc Chloride, Polydronium Chloride (Polyquad)...... is systane is safe as here it is OTC eye drop or CMC IS BETTER BUT IT IS HARD TO GET HERE.
