Abstract Details

Purpose:

ACTIVEFOCUS™ (AF) (Alcon) is an apodized diffractive multifocal intraocular lens (IOL) with +2.5 D addition power.  Implantation of AF is expected to be obtained lower frequencies of halos and glare compared to the previous multifocal IOLs and satisfactory uncorrected visual acuity (UCVA) from far to intermediate distance.  We compared postoperative outcomes between AF and Acrysof IQ (IQ) (Alcon).

Setting:

31 eyes of 21 patients with AF and 11 eyes of 7 patients with IQ, met requirements such as achieving best corrected visual acuity (BCVA) of logMAR 0 or less postoperatively.

Methods:

Assessed with measurements of all-distance logMAR UCVAs, defocus curve, contrast sensitivity, halos and glare using a simulator (Eyeland Design Network GmbH) 1 month postoperatively.

Results:

All-distance logMAR UCVAs from 50cm to 30cm were significantly better with group of AF (t-test:P<0.05). Group with AF showed a bimodal defocus curve with gentle peaks near 0 and -2.0 D, and significantly better depth of focus compared to group of IQ in the range of -2.0 D to -3.0 D( t-test: p<0.05). Both groups contrast sensitivity were normal in all range. Using simulator, patients were asked to scale their halos and glare in a range between 0 to 100% (maximum). The ratio of having less than 25% of halos and glare in group of AF was 60%.

Conclusions:

AF had less demerits compared to the previous diffractive multifocal IOLs with fine UCVA at far distance similar to multifocal IOLs and also satisfactory UCVA at intermediate distance.
