Multifocal intraocular lenses (IOLs) are being developed to improve the depth of focus of pseudophakic patients. However, the authors noted good uncorrected distance and near acuity in 32 pseudophakic patients with post-operative refraction of myopic astigmatism and round reactive pupils where a plano convex monofocal posterior chamber IOL was used. They suggest that for appropriate clinical assessment of the effectiveness and safety of multifocal IOLs, a randomized, controlled, double-masked clinical trial be undertaken to compare monofocal with multifocal IOLs. In such a trial, they suggest aiming for myopic astigmatism in the monofocal IOL group.
