  • Methods and Systems for Performing a Capsulotomy
    Publication number: 20150265470
    Abstract: A method of performing a capsulotomy comprises applying a light-absorbing agent to a lens capsule of an eye 1; illuminating the lens capsule using a first light beam and recording an image of the lens capsule using a camera 43; analyzing the recorded image and determining whether the light absorbing agent has been correctly applied to the lens capsule; if it is determined that the light absorbing agent has been correctly applied to the lens capsule, directing a shaped second light beam 19 onto a predetermined line on the lens capsule in order to modify a structure of a tissue of the lens capsule. The first light beam can be generated by defocusing the second light beam using a lens 37.
