Dry eye disease (DED) is a very common problem, and the incidence is progressively increasing. Lacrimomimetic (ocular lubricating or artificial tears) eye drops have traditionally been the first line of treatment of DED. They are also prescribed to treat related pathological conditions such as keratoconjunctivitis sicca (KCS) and other diseases of the ocular surface. Besides protecting the ocular surface, these medicines also promote epithelial regeneration. There are many lacrimomimetics available as over the counter (OTC) drugs and prescription drugs, which vary in their mechanism of action depending upon properties like electrolyte composition, osmolarity, and addition of preservatives. Knowledge of the properties of various lubricating agents and understanding the subtle differences among them will help in making the appropriate therapeutic choice.
