Paper Abstract
Cataract surgery usually involves the replacement of the natural crystalline lens with a rigid or foldable intraocular
lens to restore clear vision for the patient. While great efforts have been placed on optimising the shape
and optical characteristics of IOLs, little is know about the mechanical properties of these devices and how
they interact with the capsular bag once implanted. Mechanical properties measurements were performed on 8
of the most commonly implanted IOLs using a custom build micro tensometer. Measurement data will be
presented for the stiffness of the haptic elements, the buckling resistance of foldable IOLs, the dynamic
behaviour of the different lens materials and the axial compressibility. The biggest difference between the lens
types was found between one-piece and 3-piece lenses with respect to the flexibility of the haptic elements
