Capsulotomy: A round opening is produced within the pill (that holds the lens) to enable access to the cataract. When this step is finished with the femtosecond laser it allows for a specific circular form, dimension, and centering over the cataract and also precise placement of the brand-new lens.2.
Substitute: A brand-new lens is put into the existing pill.
Cut, cataract fragmentation, as well as capsulotomy are done with a laser tool. Insertion of the new lens is done manually.
