Accommodating iol Seks 3g

The Human Optics 1CU is a hydrophilic, acrylic, foldable, single-piece lens with a biconvex square-edge optic and 4 modified flexible haptics that allow for forward movement of the optic during accommodative effort (Figure 1).

In a similar study as that performed with the Morcher Bio Comfold IOL, median anterior movement of the Human Optics 1CU after pilocarpine 2% instillation was calculated to result in a refractive change of no more than 0.5 D in most patients 2004;115-1521).

After being placed in the aqueous at body temperature, the Medennium Smart IOL transforms into a soft gel that completely fills the capsular bag and maintains some elasticity.

The AMO Flex Optic IOL is an accommodating IOL that fills or conforms to the capsular bag and is designed to increase its anterior radius of curvature (and true power) in addition to changing its position in the capsular bag during accommodative effort.

The limitations of these IOLs stem from their inability to move significantly enough to generate large amplitudes of accommodative power that would yield consistently acceptable near visual acuities.The Morcher Bio Comfold 43E is a single-optic/ring haptic lens.During accommodative effort, the ring haptics are brought together resulting in a forward axial movement of the optic with a resultant increase in the functional power of the lens.Marchini et al reported the mean anterior axial movement of 20 crystalens IOLs to be only 0.33 ± 0.25mm 2004;76-2482).Yet, despite a mean accommodative amplitude of 1.08 ± 0.54 D (range 0-2.25), 86% of patients in this study required no correction for near vision during routine daily activities.The Nu Lens accommodating IOL is designed to change its true power during accommodation and has been shown in an animal model to deliver over 40 D of accommodation.
