Purpose To compare the visual acuity outcomes,
contrast sensitivity function (CS) and reading ability
in patients with bilateral multifocal intraocular lenses
and patients with bilateral monofocal lenses.
Setting Vizyon Eye Center, Denizli, Turkey.
Design Comparative case series.
Methods Consecutive bilateral cataract patients hav-
ing implantation of Acriva Reviol MFM 611 multifo-
cal IOLs (Group A) or Acriva BB UD 613 monofocal
IOLs (Group B) were included. Parameters analyzed
6 months postoperatively included monocular uncor-
rected distance (UDVA), binocular uncorrected inter-
mediate (UIVA), binocular uncorrected near (UNVA),
CS and bilateral reading performance using MN Read.
Results The study evaluated 42 eyes in Group A and
40 eyes in Group B. There were no statistically
signiﬁcant differences in UDVA between two groups
postoperatively (p = .39). Binocular UIVA and
binocular UNVA are better in Group A (p = .00,
p = .00). Under photopic and scotopic conditions,
contrast sensitivity results were decreased in Group A,
especially at high spatial frequencies. No statistically
difference were found in reading acuity, critical print
size and maximum reading speed between two groups
(p = .57, p = .62, p = .22).
Conclusions This study concludes that multifocal
lenses are reliable and efﬁcient replacements for
reading glasses since they signiﬁcantly improve the
vision for near or intermediate distance activities.

Cataract surgery is one of the most common surgeries
in Turkey with 385 thousand such procedures per-
formed in 2012 . Nearly all patients have presby-
opia after classic cataract surgery, diminishing the
patient’s quality of life. Modern cataract surgery
therefore aims to restore both distance and near vision
postoperatively. The new IOL models such as accom-
modating IOLs and multifocals appearing in the 1990s
have enabled clear distance and near vision and
decreased spectacle requirement. The eye does not
accommodate in the customary sense with these
lenses, and different parts of the lens are used
according to the location of the object of interest.
However, the contrast sensitivity loss and other
problems such as dysphotopsia have called the quality
of vision in eyes with a multifocal IOL into question.
