The Correcting Applanation Tonometer Surface (CATS) prism is a FDA (510K) cleared device that according to scientific studies produces clinically significant improved accuracy in intraocular eye pressure (IOP) measurements for 50% of the population over prisms currently available on the market (Goldmann prism, GAT).

SCROLL

Studies demonstrated the CATS Prism improves IOP accuracy by 94% over the GAT for this patient population. On a world-wide basis, the CATS Prism provides the eye care clinician the sight-saving IOP data required to properly diagnose and treat glaucoma and other ocular related diseases for their patients.

About

Since intraocular eye pressure (IOP) is a critical metric for assessing the ocular health of a patient, our CATS Tonometer Prism™ has the potential to greatly enhance clinical care through increased accuracy related to IOP measurements. The reusable version of the CATS Tonometer Prism™ has been cleared by the FDA for sale in the United States. Measurement of IOP is not only critical to the accurate diagnosis of ocular disease but also a necessary guide to effective treatment strategies. The CATS Tonometer Prism™ is designed to enhance IOP measurements through an easily adopted modification to the surface of the GAT prism. Additionally, the CATS Tonometer Prism™ is designed to be easily implemented by the worldwide eye care community without altering existing practitioner protocols and with minimal costs related to only changing the GAT’s tip.

Five scientific studies demonstrated the clinical performance of the CATS™ prism in comparison to the GAT prism. The peer-reviewed publications included a direct comparison to the existing GAT prism; human cadaver eye intracameral pressure transducer comparison of the CATS and GAT; an actual intracamerally placed pressure transducer comparison of the CATS and GAT in live human eyes, and tear-film hydrostatic study. All five studies confirmed our original mathematical modeling design predictions developed in a National Institute of Health, SBIR Phase I grant. IOP measurement for pediatric patients and post-corneal refractive surgery patients (LASIK, PRK, SMILE, and RK) are well-known to be highly inaccurate and might benefit from the CATS prism’s improved IOP accuracy. Further testing in these populations with the CATS Tonometer is required to examine the prism’s full potential. Our presentation on this topic won “Best Paper of Session” at the 2018 and 2015 American Society of Cataract and Refractive Surgery (ASCRS) Conference. Additionally, presentations were also made at the:

  • 2017 ASCRS Annual Meeting, Los Angeles, May 7th
  • 2018 Association for Research in Vision and Ophthalmology (ARVO) Annual Conference, Baltimore, May 8th
  • 2018 at the American Glaucoma Society (AGS) Annual Meeting in New York in March
  • 2018 ASCRS Annual Meeting in Washington DC April
  • 2018 ARVO Annual Conference in Hawaii in April

The CATS Tonometer Prism™ is FDA cleared for marketing and sale in the United States and we are in the process of securing the CE Mark.

Sean McCafferty, MD FACS
CHIEF EXECUTIVE OFFICER

Dr. McCafferty founded Intuor Technologies, LLC and serves as the Chief Executive Officer. He possesses solid expertise in mechanical engineering, optical engineering, and optical engineering, and ophthalmology coupled with demonstrated entrepreneurial skills. This depth of understanding in all three fields is critical to producing products with a wide variety of optical and ophthalmic applications. After completing his undergraduate degree in mechanical engineering, he worked as a product development engineer developing ideas, patents, and profitable products. He then attended the Ohio State University’s Medical School and subsequently completed a residency in ophthalmology at the University of Arizona.

Following residency, Dr. McCafferty became a serial entrepreneur and business manager founding very successful enterprises such as Arizona Eye Consultants, Camp Lowell Surgery Center, Carondelet Foothills Surgery Center, and Intuor Technologies, LLC. Simultaneously, he completed a Master of Science (MS) degree in optical engineering at the University of Arizona expressly to allow his ideas to become reality in the form of products for the ophthalmic industry. During his optical engineering education, Dr. McCafferty’s ophthalmic opto-mechanics research was self-directed under the mentorship of Jim Schwiegerling, Ph.D. He authored several peer-reviewed articles and papers on the subject. In 2017 the University of Arizona Alumni Association selected Dr. McCafferty as the 2017 Alumnus of the Year for the College of Optical Sciences. Click here to see a listing of his publications. Additionally, Dr. McCafferty has produced 10 patents or published patent applications on ophthalmic opto-mechanics.
