title: Biomechanical properties of the Ong capsular lens and results of four years of clinical experience.
abstract: We developed a capsular supported lens based on a biomechanical concept. Specific management of the anterior and posterior capsules ensured double capsular pocket fixation. For safe as well as atraumatic insertion, we applied the basic movement of the "downward swinging of a falling leaf," that worked effectively within a shallow anterior chamber. Because of the irido-lenticular clearance, the classic iridectomy was not indicated. Reconstituting the posterior chamber and artificially deepening it contributed to the integrity of the pupillary functions. The absence of capsular and zonular ruptures, the low rate of dislocations, decentrations and secondary capsule opacification in 200 lens implantations confirmed the biomechanical concept.
