PROBLEM
Glaucoma, which is caused by an increase in intraocular pressure (IOP), is the second-leading cause of blindness worldwide; it affects approximately 80 million people and causes a global economic burden of $6 billion annually. The industry standard method for measuring IOP is Goldmann applanation tonometry, which requires clinic visits.
SOLUTION
Researchers at Purdue University have developed smart soft contact lenses that continuously monitor intraocular pressure (IOP) with improved diagnostic accuracy compared to the commercial standard. The lenses monitor IOP in real-time and at home. They consist of a wireless tonometer integrated in commercial soft contact lenses and conform seamlessly to the human eye without restricting comfort level like other soft contact lenses. The tonometer is > 10 times softer and thinner than typical soft contact lenses and confers more sensitivity compared to other smart lenses.

QUOTE
“The smart lenses developed by Dr. Lee improve patient care for individuals diagnosed with chronic glaucoma. Through constant IOP monitoring, patient’s peace of mind and comfort improves along with long-term outcomes. Additionally, the soft texture lenses and their higher sensitivity compared to standard methods advance glaucoma treatment and vision care.” Raquel Peron, Licensing Associate – Life Sciences
