During accommodative effort, the 2 lens components increase their distance from each other, resulting in increased effective power of the overall lens.The dual-optic design offers potential advantages over single-optic designs in that less lens excursion is necessary with the dual-optic in order to achieve a desired amount of accommodation (Figure 3) 2003;84-2287).Marchini et al reported the mean anterior axial movement of 20 crystalens IOLs to be only 0.33 ± 0.25mm 2004;76-2482).

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).Accommodating IOLs may very well transform the practice of cataract and refractive lens surgery.This is because accommodative IOLs can potentially provide unaided near visual acuity without the optical aberrations and image degradation that may accompany multifocal IOL implantation.The eyeonics crystalens is a 10.5 mm, hinged plate haptic silicone lens with a 4.5 mm optic (Figure 2).It is the only accommodating IOL that has been approved by the FDA.
