High speed optical coherence tomography image guided femto-second laser cataract surgery system

Abstract

We developed the optical coherence tomography (OCT) image referenced microsurgical system for ocular anterior segment. The system combined a swept-source OCT and a femto-second laser and afford the 2D and 3D structure information to increase the efficiency and safety of the cataract procedure. The OCT imaging range was extended to achieve the 3D image from the cornea to lens posterior. The surgeons can plan the laser illumination range for the nuclear division and segmentation, and monitor the whole cataract surgery procedure using the real time OCT. The surgery system was demonstrated with an extracted pig eye and in vivo rabbit eye to verify the system performance and stability.
