Paper Abstract

This paper gives a description of the use of Optical Coherence Tomography to localize the Ex-PRESSTM mini implant placed in the anterior segment of the eye. An OCT scanner, central wavelength 1280 nm, bandwidth 60 nm, resolution of 12 μm, was build onto a slitlamp to scan the anterior segment of the eye. Five ex-vivo porcine eyes received an Ex-Press implant, and were used as a model to visualize the position of the implant in the anterior segment. In the ex-vivo porcine eyes the OCT images showed the anatomy of the anterior segment in great detail. The anterior segment OCT was able to visualize the whole outline, and the position of the implant. The acquisition time of 0.8 sec is short enough to allow for scanning patients, and AS-OCT is expected to aid in providing answers to the question which parameters will determine the success or failure of such a device.
