Tecnis ZLB00 multifocal IOL improves near, intermediate, distance visual acuity

An aspheric, bifocal, diffractive multifocal IOL with low near addition restored near, intermediate and distance visual acuity, according to a study.

The prospective multicenter clinical study included 44 eyes of 44 patients who underwent cataract extraction and implantation of a Tecnis ZLB00 multifocal IOL (Abbott Medical Optics) with a near addition of 3.25 D on the IOL plane.

Investigators evaluated changes in logMAR uncorrected and corrected near, intermediate and distance visual acuity and manifest refraction 3 months after surgery. Patients were asked to evaluate photic phenomena, spectacle dependence and overall satisfaction.

Postoperative monocular logMAR uncorrected distance, near, and intermediate visual acuities were 0.1 or better in 82.5%, 86.5% and 68.8% of eyes, respectively.

Monocular corrected distance and near visual acuity of 0.1 logMAR was achieved in all eyes. Monocular corrected distance visual acuity improved significantly (P = .001).

Postoperative spherical equivalent was within 0.5 D of emmetropia in 91.2% of eyes and within 1 D in 100% of eyes.

Manifest sphere and cylinder decreased significantly after surgery (P = .030 and P = .021, respectively).

All patients were at least moderately satisfied with surgical outcomes. Six patients (13.6%) required spectacles for some daily activities. Eight patients (18.2%) reported mild halos.

No severe intraoperative or postoperative complications occurred. – by Matt Hasson
