Fixation within the capsular bag appears to be generally, if not unanimously, accepted for optimal positioning of an intraocular lens. It furthermore seems apparent to us that each lens model relates to a specific position within the eye and fixates better according to its particular geometry. In our opinion, the Frezzotti-Caporossi lens represents one of the better solutions for in-the-bag fixation because of the static action of the haptic and the extended contact between loops and the enclosing structures.
