RTVue TCP Report
Utilization of TCP provides an important and novel piece to the puzzle in obtaining accurate biometry. This is particularly crucial in eyes that have had prior corneal procedures including refractive procedures such as LASIK. Incorporating this measurement into IOL selection has given me additional assurance of proper lens selection.
Jason Bacharach, MDDirector of Research at North Bay Eye AssociatesCalifornia Pacific Medical Center, Vice-Chair of Glaucoma Division, San Francisco / Petaluma Valley Hospital
PROBLEM: • Post refractive patients, especially those choosing premium IOL's, are increasing in number and are challenging as they have higher expectations. • K-values from keratometry, IOL Master and topography on post refractive patients are difficult due to the fact that these instruments only measure the front corneal surface and use the ratio of 82% to assume the back surface. In post refractive patients, this ratio may no longer be valid and could lead to post operative surprises. • Scheimpflug imaging systems directly capture front and back measurements however the slow capture speed, 15 micron resolution (versus 5 micron for SD-OCT), and fluctuating angle of capture make addressing post refractive patients problematic.
SOLUTION: RTVue with Total Corneal Power (TCP™) • Unique in the market - The only SD-OCT that provides corneal power to date • Directly measures the anterior and posterior surface of the cornea – no assumed ratio • 5 micron resolution • Excellent repeatability*
