With Access to iVIZIA in Retail Pharmacies, Physicians Can Now Recommend a Line of Preservative-Free Products for Dry Eye and Eyelid Relief

LEXINGTON, Mass.–(BUSINESS WIRE)–Théa Pharma Inc. (“Thea”), the U.S. subsidiary of Europe’s leading independent pharmaceutical company specializing in the research, development and commercialization of eye care products, has today announced the availability of the iVIZIA line of over-the-counter eye care products in the United States.

The iVIZIA OTC product line includes lubricating eye drops, lubricating eye gel and three options for the daily hygiene of sensitive eyelids. iVIZIA eye drops provide long-lasting relief and ocular surface protection without preservatives for patients with any type of dry eye, including those who wear contact lenses.1 The eye drops come in a patented multi-dose bottle developed by Théa which protects against contamination while reliably dispensing a single calibrated drop dose at a time to avoid the nuisance and waste caused by the runoff of drops encountered with other multi-dose bottles. For very dry eyes, iVIZIA Eye Lubricating Gel is also available in preservative-free single-use bottles. Besides the inclusion of povidone, iVIZIA Lubricating Eye Drops have the same formulation as Thealoz® Duo, the #1 prescribed dry eye drop in Europe. Eyecare professionals and their patients in the United States will also have access to three eyelid hygiene formulas that have become trusted global products. They gently remove oils and makeup from dry, irritated and sensitive eyelids: iVIZIA Eyelid Cleansing Wipes, iVIZIA Eyelid Micellar Cleanser and iVIZIA Eyelid Cleansing Gel. All three products are BAK-free and require no rinsing after use.

The iVIZIA brand is distributed by Colorado-based Similasan Corporation, known for its natural homeopathic products for eye, ear, sinus and cold relief. Théa and Similasan had previously formed a partnership of which Théa recently became the majority shareholder. The iVIZIA line is now available through Amazon and CVS and will hit the shelves of more than 26,000 retail stores by July. Eye Care Professionals can request samples by visiting the iVIZIA website

“We are thrilled to partner with Similasan to provide eyecare professionals across the United States with a portfolio of new options for patients who need complete relief from dry eyes or eyelids – without preservatives that can damage the skin. ocular surface,” said Susan Benton, Managing Director, US Lead, Théa. “As a global driving force committed to advancing preservative-free treatments in eye care for the past 28 years, Théa wholeheartedly embraces this latest opportunity to improve the quality of life for patients in all areas of care. eyes with these innovative product offerings.

iVIZIA Eye Drops provide long-lasting dry eye relief by combining ingredients proven to target every point in the vicious dry eye cycle:

  • Povidone, the active ingredient to improve viscosity and provide moisturizing and lubricating properties;

  • trehalose, a disaccharide which provides ocular bioprotection, osmoprotection and rehydration 4,5,6,7; and

  • Hyaluronic acid, a component of the tear film with the ability to lubricate, can bind 1000 times more water than its weight.

Clinical studies have shown that the combination of 3% trehalose and 0.15% hyaluronic acid found in both dry eye products:

  • increased tear thickness at 240 minutes from one application 7.6 times longer than hyaluronic acid alone

  • provided a majority of patients with greater improvement in scores on the Ocular Surface Disease Index5 compared to hyaluronic acid alone

  • decreases inflammation of the ocular surface; and

  • relieves symptoms including blurred vision, tingling and itching.5

“As the first user of the iVIZIA product line, I have recommended the Lubricating Eye Drops to my patients who suffer from dry eye or experience dryness and discomfort while healing from surgery, and have received outstanding feedback and noted remarkable clinical improvements in those using iVIZIA,” said Mile Brujic, OD, FAAO of Bowling Green, Ohio. “I love that it’s formulated to target every point in the vicious cycle of eye dryness. The easy-to-use, preservative-free multi-dose vial is a great option for patients.”
