Multifocal IOLs are effective for providing near vision and reducing the need for additional spectacle correction in pseudophakic patients, according to a literature review.
M. Leyland and E. Zinicola searched a reference list of articles that was created through a search of the Cochrane Central Register of Controlled Trials, a part of the Cochrane Library, and through Medline and EMBASE. Manufacturers of multifocal IOLs were also contacted for additional published or unpublished studies.
Of the eight randomized, controlled trials identified that met inclusion criteria, the authors noted there was significant variability among reported outcomes.
According to the review, unaided distance vision was similar between multifocal and monofocal IOL groups. No statistical difference was seen in the proportion of patients achieving 6/6 best corrected visual acuity.
Unaided near vision was improved in patients with multifocal IOLs, the review found. Also, more multifocal IOL patients were free from spectacle correction.
The study is published in The Cochrane Library.
