3-D Imaging Guides Femtosecond Laser in Cataracts Removal (5 of 10) (IMAGE)
Caption
These are images and cutting patterns produced by the system. (A) optical coherence tomography (OCT) image of the eye with outlined boundaries of the cornea (1 and 2) and lens capsule (3 and 4). The capsulotomy pattern (5) and lens segmentation pattern (6) are shown in solid red. (B) View of the eye via the near-infrared video camera, with overlaid guidance lines indicating a planned capsulotomy pattern (1) and a boundary of the pupil (2). (C) Top view of the circular capsulotomy pattern, a cross-pattern for lens segmentation, and the nucleus fragmentation pattern. (D) Three-dimensional representation of the capsulotomy and cross-segmentation patterns in the lens alone (left) and inside the eye. (right). Scale bars, 3 mm. This image relates to an article that appeared in the Nov. 17, 2010, issue of Science Translational Medicine, published by AAAS. The study, by Daniel V. Palanker of Stanford University in Stanford, Calif., and colleagues, was titled, "Femtosecond Laser-Assisted Cataract Surgery."
