Santen Announces Health Canada Approval for Cationorm® Plus to Relieve the Symptoms of Dry Eye and Ocular Allergy

Dry eye occurs when there is a problem with the tear film that normally keeps the eyes moist and lubricated.^1,2,3 Symptoms of dry eye include redness, burning, stinging, itching, sensitivity to light, and a feeling like something is in the eye.⁴ It is estimated that about 21% of Canadians have dry eye, or about 6.3 million people.⁵ Ocular allergy involves inflammation of the conjunctiva, and symptoms that can be seasonal or year-round and may include itching, tearing, redness, and pain.^6,7,8 Ocular allergies affect up to 1 in 5 people around the world. Both conditions can impact the quality of life for an individual, interfering with aspects of daily activities and work productivity.^{9,10,11,12,13}

“Millions of Canadians are impacted by the discomfort and potentially lifestyle-limiting symptoms associated with dry eye and ocular allergy. Artificial tears are considered the first-line treatment to relieve these symptoms,” stated Craig Wallace, General Manager of Canada, U.K., Ireland, and South Africa at Santen. “We are pleased that with this approval, doctors and patients in Canada will now benefit from the first artificial tear that uses a positive cationic emulsion to provide improved hydration in the eye. The approval of Cationorm^® Plus is also a significant step forward in our ongoing growth in Canada and throughout North America.”

Cationorm^® Plus is a sterile, preservative-free, artificial tear containing the novel Novasorb^® technology. As the only artificial tear that uses positive cationic emulsion to hold hydration in place, Cationorm^® Plus protects, hydrates and lubricates the eye while supporting the healing of the cornea (the transparent front part of the eye). Cationorm^® Plus is safe for daily use and restores the three layers of the tear film on the eyes to offer relief from eye irritation and discomfort.

About Dry Eye and Ocular Allergy

Dry eye is an ocular condition with symptoms such as redness, burning, stinging, itching, sensitivity to light, and a feeling like something is in the eye.⁴ Globally, dry eye may affect up to half the population. Both men and women can have dry eye, although it tends to affect more women.¹⁴ Those of increased age, wearers of contact lenses, and those who frequently use computer or other digital screens are more likely to experience dry eye.⁴ Dry eye occurs when there is a problem with the tear film that normally keeps the eyes moist and lubricated, leading to inflammation and damage. Either tear fluid is no longer produced in sufficient quantity, the quality of tear fluid has changed or the tear fluid evaporates too much.^1,2,3

Ocular allergy involves inflammation of the conjunctiva, and symptoms that can be seasonal or year-round and may include itching, tearing, redness, and pain. Ocular allergies affect up to 1 in 5 people around the world, and are most common in females.^6,7,8 Factors that may cause someone to experience an ocular allergy include grasses, trees, fungal spore, dust mites, and animal dander.^15,16 Having an ocular allergy increases a person’s risk of developing dry eye.¹⁷

Both conditions can impact the quality of life for an individual, interfering with aspects of daily activities and work productivity. In severe cases, the conditions may even lead to visual damage.^{9,10,11,12,13}
