Lubrithal eye gel for dogs is a sterile eye drop for dry eyes. The gel is a carbomer lubricating fluid which helps moisturise the tear layer of the eye. Most eye lubricators just add moisture to the cornea; this carbomer moisturiser retains moisture in the tear film for far longer. Please apply as required or as directed by your veterinary surgeon. Ingredients: Aqua, Sorbitol, Carbomer, Sodium Hydroxide, Cetrimide, Disodium EDTA.
