A new report suggests that vitamin E contact lens solutions could greatly enhance ciprofloxacin binding. All of these studies were done using some of the most popular silicone-based soft contact brands. In layman's terms, this vitamin E solution could help with the release of artificial tears.
Researchers involved in this study tested their vitamin E solution on Biofinity, Acuvue Oasys, and Air Optix soft silicone-based lenses. No matter what lens was being tested, researchers found a remarkable increase in ciprofloxacin binding with the addition of vitamin E. For those who don't know, the companies behind these contacts are CooperVision, Johnson & Johnson Vision, and Alcon respectively.
After the doctors put the contacts in vitamin E solutions, they measured their results from an artificial tear. Just by looking at this tear, doctors were able to determine both the ciprofloxacin loading amount and drug releasing profile.
Vitamin E works so well on these contacts by effectively creating a hydrophobic barrier. This barrier had the effect of decreasing the overall water content in the soft contacts.
Specifically, researchers said contacts dipped in vitamin E solutions increased in diameter between 5% – 18% when hydrated and 11% – 23% when dry. In terms of ciprofloxacin binding, a vitamin E solution of 0.2-g/mL resulted in an increased binding of 27.94% – 37.08%.
This isn't the first time contact lens researchers have discovered the benefits of using vitamin E in contact lens solutions. Not only could vitamin E address dry eye symptoms, it could also help keep more serious eye diseases under control.
Believe it or not, some doctors are advocating for vitamin E laced contacts specifically designed for glaucoma patients. Some studies suggest using vitamin E on medicated contacts could keep glaucoma medication near a person's eye 100 times longer than traditional contact lenses.
Vitamin E is extremely important in the body's immune system. Not does vitamin E help with eye problems, it also protects skin cells, the heart, and the liver. People who consume a healthy amount of vitamin E every day could even help prevent diseases like age-related macular degeneration and cataracts.
A few of the top foods with high doses of vitamin E include sunflower seeds, almonds, mangos, and avocados. Anyone without a vitamin E deficiency interested in taking a dietary supplement should take no more than 15mg per day.
