Purpose of review The manuscript presents a review of recently published studies reporting objective and subjective outcomes and preoperative considerations of asymmetrical multifocal intraocular lenses (IOLs).

Recent findings Current publications suggest that asymmetrical multifocal IOLs provide good, distance, intermediate and near vision for cataract and clear lens extraction patients. The contrast sensitivity achieved is similar to monofocal IOLs. Photopic phenomenon such as glare and halos has been reduced through the use of these IOLs leading to better patient satisfaction. Centration plays a critical role and the lack of a gold standard assessment tool has led to a minority of patients experiencing lower quality of vision and side-effects such as glare and hazy vision. The frequency of dissatisfied patients can be minimized by appropriate patient selection. This is achieved by assessing pupil parameters which guides the surgeon to align the IOL accordingly.

Summary Asymmetric multifocal IOLs provide the surgeon with an IOL that achieves excellent visual and refractive outcomes enabling patients to see clearly at a range of distances. Subjectively patients report low levels of photopic phenomena and high levels of spectacle independence resulting in high overall patient satisfaction.
