Multifocal versus monofocal intraocular lenses after cataract extraction

The use of multifocal intraocular lenses appears to improve near vision without any adverse effect on distance acuity, and to increase spectacle independence, at the cost of a reduction in contrast sensitivity and the experience of haloes compared with monofocal intraocular lenses.

A Cochrane review included 20 studies with a total of 2230 subjects. Most studies compared multifocal and monofocal lenses but there was considerable variety in the make and model of lenses implanted. Similar distance acuity was achieved with both types of lenses. People with multifocal lenses had better near vision and were less spectacle dependent (table . Adverse subjective visual phenomena, particularly haloes, or rings around lights, were more prevalent and more troublesome in participants with the multifocal lenses and there was evidence of reduced contrast sensitivity with the multifocal lenses.
