ABSTRACT
Comparison of monofocal and accommodating
intraocular lenses in patients with cataract
Introduction: The aim of this study is to compare the
visual outcomes of monofocal and accommodating
intraocular lenses in patients with cataract.
Material and Method: 42 eyes of 26 patients with
cataract were included in this retrospective study. 21
eyes of 13 patients (8 patients had bilateral, 5 patients
had unilateral surgery) had WIOL-CF accommodating
intraocular lens implantation and they classified as
Group 1. Other 21 eyes of 13 patients (8 patients had
bilateral, 5 patients had unilateral surgery) had Acriva
monofocal intraocular lens and they classified as Group2.
Follow-up time was 6 months for both groups. Distance
and near vision results were compared between two
groups. Also changes in corneal endothelial cell count
and intraocular pressure were evaluated in each group.
Results: At postoperative sixth month mean bestcorrected visual acuity was 0.91±0.1 (range: 0.7 and 1)
in Group 1 and 0.9±0.1 (range: 0.7 and 1) for Group2.
Mean uncorrected near vision for Group1 was 1.52±1.03
(range: Jaeger1 and Jaeger4). Near visual acuity was
statistically significantly better in Grup 1 against Grup 2.
(p<0.05) After 6 months follow up time, there was no
significant change in corneal endothelial cell count and
intraocular eye pressure for both groups.
Discussion: With WIOL-CF accommodating intraocular
lens, successful distance vision results as Acriva
monofocal intraocular lens can be achieved in patients
with cataract. Additionally near vision can be obtainable.
