Abstract
Weak capsular support can make cataract significantly more challenging. The design of the BIL implant can be of assistance in coping with these cases. Two specific techniques, lasso suturing and the bean-shaped segments, can be used to stabilize the BIL capsule complex and are described in this chapter.
