PURPOSE OF REVIEW This review examines the recent peer-reviewed literature of the past 18 months, with the goal of providing an overview of the pseudophakic lenses designed to provide accommodative action. Accommodative lenses take advantage of axial movement, refractive change and bag filling to provide their effect. Single and dual optic design, as well as unique technologies, were reviewed. RECENT FINDINGS An overview is presented of the various accommodative lenses available for investigation and use. There is positive evidence that current accommodative intraocular lenses provide superior potential for near vision compared with standard intraocular lenses. SUMMARY The available data suggest that accommodative amplitude and pseudoaccommodation are both important factors in the functional ability of accommodative intraocular lenses to provide a range of distance, intermediate and near vision.

Purpose To evaluate the position of posterior chamber intraocular lenses (PC IOLs) at distance and near and the amplitude of pseudoaccommodation in young eyes. Setting Department of Ophthalmology, University School of Medical Sciences, Bydgoszcz, Poland. Methods This study comprised 45 eyes of 38 patients aged 12 to 19 years who had removal of congenital cataract with implantation of a PC IOL. During the follow-up, the refractive error ranged between −1.00 and +1.00 diopter (D), and near visual acuity was 0.75 or 0.50 (Snellen) without additional correction. The position of the PC IOL was measured by A-mode ultrasound at distance and near. Pseudoaccommodation amplitude was calculated using Gullstrand's near-point rule. Results Mean anterior movement of the IOL was 0.42 mm at near. Mean pseudoaccommodation amplitude was 4.50 D. The correlation between these values was significant ( P Conclusion The movement of PC IOLs in young patients may be one reason they attain good near vision without additional correction.
