Alcon has expanded its range of preservative-free eye drops for dry eye disease with the addition of Systane Complete Preservative-Free.
Using Systane’s delivery system of hydroxypropyl-guar (HP-Guar) and borate in combination with nano-lipid technology to support all layers of the tear film, Alcon said the revised drop relieves the symptoms of all types of mild-moderate dry eye (aqueous deficient, evaporative and mixed dry eye) for up to eight hours.
“Upon instillation, the HP-Guar and borate crosslink to form a viscoelastic meshwork, creating a ‘bandage’ over the ocular surface, preferentially binding to damaged areas of the cornea and increasing retention of the demulcents in the drop, for extended protection and lubrication.”
