MICS, multifocal IOL achieve good vision, study shows

NAPLES, Italy — Microincision cataract surgery with implantation of the Acri.Tec multifocal Acri.Lisa 366D IOL seems to meet the requirements of today's active patients, according to one speaker here.

At the joint meeting of Ocular Surgery News and the Italian Society of Ophthalmology, Jorge L. Alió, MD, PhD, said he used this lens in 69 eyes of 52 patients with a mean age of 59 years and a mean spherical equivalent of +1.22 ± 3.62 D. Visual and optical outcomes were evaluated 6 months postoperatively by measuring refraction, binocular uncorrected and corrected visual acuity for far and near (40 cm), intraocular aberrations, Strehl ratio and modulation transfer function.

The postoperative spherical equivalent was +0.39 ± 0.51 D, with 70% of the eyes within ±0.5 D and 86% of the eyes within ±1 D. Mean visual acuity at distance was 20/25 uncorrected and slightly less than 20/20 best corrected. More than 90% of the patients were able to read J1.

"The Acri.Lisa offers clinically outstanding efficacy, predictability, safety and excellent visual results at distance and near," Dr. Alió said. "Excellent values were also found for optical aberrations, Strehl ratio and [modulation transfer function]."

This lens "fits the concept of MICS well because the small corneal incision has minimal impact on astigmatism and corneal aberrations compared to coaxial conventional phacoemulsification."

"This minimally invasive impact, in terms of induced refractive and aberrometric changes, is a condition for multifocal IOLs to work effectively," he said.
