Abstract Details



Purpose:

To evaluate the visual outcomes and contrast sensitivity after unilateral implantation or bilateral implantation of a diffractive multifocal intraocular lens (IOL).

Setting:

Marmara University, School of Medicine, Department of Ophthalmology, Istanbul, Turkey

Methods:

The study enrolled 30 eyes of 20 patients. Uncorrected distance (UDVA), intermediate (UIVA), and near (UNVA) visual acuities; corrected distance visual acuity; distance-corrected intermediate and near visual acuities and contrast sensitivity measurements with and without glare were assessed before and one month after surgery.

Results:

The preoperative and postoperative data were comparable in the 2 groups. Ten participiants with a mean of age of 46ḟ6.25 years were in the bilateral multifocal group, ten participiants with a mean of age of 29.7ḟ6.25 years were in the multifocal-phakic group. There were not statistically significant postoperative differences in uncorrected near visual acuity (Bilateral group, 0.03ḟ0.06 (SD) logMar; unilateral group, 0.12ḟ0,2 (SD) logMar; p = 0.17). However, the bilateral group (0,17ḟ0,1) had significantly better UIVA than the unilateral group (0,34ḟ0,2) (p = 0.03). In all operated eyes uncorrected distance visual acuity was 20/20 for bilateral and unilateral group. Contrast sensitivity was similar between groups without glare (p > 0.05). However, bilateral group had a better contrast sensitivity with glare than unilateral group and it was statistically significant (p < 0.05).

Conclusions:

In non-presbyopic patients with unilateral cataract, unilateral multifocal intraocular implantation is a good treatment option as it provides satisfactory visual outcome and spectacle independence.
