Abstract Details

Purpose:

Comparison of the spectacle independence and intermediate vision between bilateral multifocal lenses and pseudophakic monovision.

Setting:

Vienna Institute for Research in Ocular Surgery, Department of Ophthalmology, Hanusch Hospital, Vienna.

Methods:

In this randomised, controlled trial 140 eyes of 70 patients were included. Standard cataract surgery with phacoemulsification and irrigation/aspiration of cortical material was performed. The IOL to be implanted was allocated by randomization. One group received multifocal IOLs with a low near add (Lentis comfort bilateral, +1.50D near addition, target refraction 0 – 0.50D) and the other group monofocal IOLs with moderate monovision (Lentis L-313, monofocal, target refraction of the distance-dominant eye: 0 – 0.25D, target refraction of the other eye: -1.50D). Three months postoperatively the distance visual acuity measurements were assessed using ETDRS charts (Precision Vision) at 4m, intermediate visual acuity will be assessed at 80cm and near visual acuity at 40cm.

Results:

In the monovision group the uncorrected distance visual acuity averaged -0.06 (logMAR), while the patients with the multifocal IOLs had -0.07. In the intermediate distance the patients of the monovision group achieved an uncorrected visual acuity of 0.1 and in the multifocal group 0.05. The monovision group achieved an uncorrected near visual acuity of 0.22, whereas the patients with the multifocal IOLs had 0.13. On direct questioning, approximately 60% of patients in both groups reported to perceive occasional glare and/or halos.

Conclusions:

Both groups showed good spectacle independence in the distance, intermediate and near range. Patients from both groups experienced glare and halos.
