Abstract Details

Purpose:

To evaluate the effect of binocular summation on near visual acuity in patients who have undergone bilateral implantation of a polyfocal bioanalogic intraocular lens.

Setting:

Department of Ophthalmology, University Hospital Královské Vinohrady and 3rd Medical Faculty, Charles University, Prague, Czech Republic.

Methods:

Fifty four patients with an average age of 62.6 ± 8.3 years (range: 47 to 82 years) underwent bilateral standard cataract surgery with implantation of a polyfocal bioanalogic IOL (WIOL-CF, Medicem). Uncorrected monocular and binocular near visual acuity (UNVA) was measured on average 12 months following the surgery of the second eye using the standard reading chart (logMAR, 40cm). Difference between binocular and better eye monocular near visual acuity was compared to evaluate the effect of binocular summation.

Results:

Mean ± standard deviation UNVA was 0.34 ± 0.17 and 0.44 ± 0.16 logMAR comparing the better and worse eye, improving to 0.28 ± 0.15 logMAR binocularly. Binocular summation, defined as the difference between the binocular and better eye monocular near visual acuity, was found to be statistically significant (P<0.05).

Conclusions:

The results of the study showed, that there was statistically significant benefit of bilateral implantation of polyfocal bioanalogic IOL in terms of improved near visual acuity.
