Abstract Details

Purpose:

To assess intermediate visual acuity after cataract surgery with the implantation of four different model multifocal intraocular lenses.

Setting:

Department of Ophthalmology, Medical Academy, Lithuanian University of Health Sciences.

Methods:

This prospective study evaluated intermediate visual acuity over a 6-month period after cataract surgery with bilateral implantation of the following multifocal IOLs: Rayner M-flex (M-flex), TECNIS ZMB00 (TECNIS), Acrysof ReSTOR (ReSTOR) and AT.LISA tri 839 MP (AT.LISAtri). Monocular and binocular LogMAR uncorrected intermediate visual acuity (UIVA) and corrected intermediate visual acuity (CIVA) were recorded.

Results:

The study involved a total of 170 eyes of 85 patients. Monocular UIVA was statistically significantly better (p<0.01) in the AT.LISAtri group (mean LogMar 0.07) than in all other groups, as was the ReSTOR group (mean LogMAR 0.17) in comparison with the M-flex group (mean LogMAR 0.26) and TECNIS group (mean LogMAR 0.46). Binocular UIVA was higher than monocular in all four groups: AT.LISAtri (mean LogMAR 0.04), ReSTOR (mean LogMAR 0.11), M-flex (mena LogMAR 0.22) and TECNIS (mean LogMAR 0.40).

Conclusions:

UIVA was better in apodized diffractive and diffractive trifocal multifocal IOL designs, rather than refractive and bifocal diffractive optical designs. Binocular intermediate visual acuity was higher in all groups than monocular visual acuity. FINANCIAL INTEREST: NONE
