An economic analysis of the wireless intraocular pressure transducer (WIT)
Glaucoma is a condition that affects millions of Americans and is the second most prominent cause of blindness worldwide. In addition, the disease inflicts a significant financial burden on the U.S. Medicare system. Among many risk factors for blindness, intraocular pressure (IOP) is the only one that can be effectively altered by physicians. While a rigorous monitoring of IOP will improve the care of patients through early diagnosis and prompt treatment, the frequent visits patients must make to the clinic will aggravate their financial burden. The wireless intraocular pressure transducer (WIT) shows potential in effectively reducing cost inflicted by glaucoma, while maintaining the quality of patient care. The WIT shows the promise of reducing clinical visits for IOP measurements and preventing the progression of glaucoma. Direct and indirect savings, as well as cost of implantation will be analyzed through the construction of a flexible model using currently available data. The model yields favorable outcomes in the cost-reduction effectiveness of the WIT, but suggests a clear indication that further information is needed in order to make an accurate and complete assessment.
