Purpose To analyze the existing lenses designs, properties as well as the new intraocular lens technology in the field of accommodative IOLs.Moreover, to distinguish the difference between accommodation and pseudoaccommodation. Methods The restoration of near vision in elder individuals that have entered the presbyopic age is considered one of the major challenges in refractive surgery during the last decade. Accommodative IOLs offer to patients satisfactory near vision by restoring to some degree the dynamic component of the ocular ability for near vision. By implementing several designs of the haptic and the optic part of the IOL, the target is to take advantage of the movement of the ciliary muscle and of the vitreous in order to change position and shape. This offers a change of the overall dioptric power of the eye and the facilitation of near vision. Results Pseudophakic patients’ ability for good distance and near visual acuity without correction has been characterized as apparent accommodation, or pseudoaccommodation. It has been attributed to several factors such as the pupil size, total and corneal aberrations, degrees and axis of astigmatism, potential of visual perception and axial movement of the intraocular lens.the i‐Trace technology has an important role in the evaluation of accommodation and pseudoaccommodation in pseudophakic eyes not only subjectively but optically. Conclusion Accommodative IOLs represent the future in the battle for the correction of presbyopia and restoration of near vision.
