Clinical indications
St Constant therapeutic tears can be used in the following situations:
Corneal epithelial regenerationespecially after trauma, surgery or corneal ulcers;
Improved trophicity of the ocular surfacein cases of neurotrophic keratitis or growth factor deficiency;
Support for certain retinal treatmentsas an adjuvant to reduce inflammation or oxidative stress, as a complement to specific therapies.
Mode of action
These enriched tears generally contain bioactive agents: growth factors, vitamins, amino acids or mild anti-inflammatory components. They help to :
Promotes corneal healing,
Reduce local inflammation,
Restore the balance of the tear film,
Protect retinal cells from certain metabolic and environmental stresses
