Contact Lenses With Antihistamines
Allergy season can make your eyes itchy and red, and relief often comes in the form of eye drops. What if contact lenses were preloaded with an antihistamine to help reduce that itchiness caused by allergies?
Researchers at Johnson & Johnson Vision Care say single-use contact lenses that dispense the antihistamine ketotifen showed promising results in two Phase 3 clinical trials. Results of the study were published in the journal Cornea in March.
Lead investigator Brian Pall, director of clinical science at Johnson & Johnson Vision Care, says antihistamine-dispensing lenses "look promising in their ability to reduce eye itch".
Why put antihistamines in contacts? "Eye drops are contraindicated for contact lens wearers," Pall says. The itchiness caused by allergies leads the contact lens wearer to rub his or her eyes, possibly damaging the lenses.
Contact lens wearers now must take out their contacts, apply eye drops and then switch to glasses until the antihistamine takes effect.
