Femtodelineation to enhance safety in posterior polar cataracts.

UNLABELLED: We describe the technique of femtodelineation for posterior polar cataracts. In this technique, the femtosecond laser is used with a cylindrical pattern of lens division to create multiple cylinders within the lens, which results in sharply demarcated layers. The number, size, and depth of the cylinders can be controlled by the surgeon using the live anterior segment optical coherence tomography view. The multiple layers act as mechanical cushions that protect each layer as it is removed. Because of its sharp demarcation, the last epinuclear layer can be easily stripped using a combination of the phaco probe and bimanual irrigation/aspiration. This approach eliminates the need for any type of hydro procedure in posterior polar cataracts. It reduces posterior capsule rupture rates and enhances safety in posterior polar cataract emulsification.
