BARCELONA — Results obtained with the Acri.Lisa toric bifocal IOL show promise and are a step forward in phacorefractive surgery, according to surgeons speaking here.

Detlev Breyer, MD, of Düsseldorf, Germany, presented results of microincision cataract surgery with implantation of the Acri.Lisa (Acri.Tec) multifocal toric IOL at the winter meeting of the European Society of Cataract and Refractive Surgeons. Initial results are “promising, even in patients with high astigmatism and myopia or after keratoplasty,” he said.

Jorge Alió, MD, of Alicante, Spain, also reported his results implanting the lens either alone (46 eyes) or in conjunction with a capsular tension ring (CTR; 32 eyes). In the study, Dr. Alió measured optical quality using the VOL-CT software (Saver and Associates) and evaluated differences in total aberrations, higher-order aberrations, spherical and coma aberrations, Strehl ratio and modular transfer function (MTR).

“Results were excellent in both groups, but the group implanted with both the Acri.Lisa and the [CTR] showed statistically significant reductions in intraocular aberrations compared with the group implanted without the CTR. A statistically significant increase in Strehl ratio and MTF was also observed,” Dr. Alió said.

These results, he said, show that the Acri.Lisa is an “excellent option” for astigmatic patients undergoing refractive cataract surgery, and that the use of a CTR can improve the results by enhancing lens stability.
