Microincision IOL performs well in multicenter European study

BARCELONA — Preliminary results of a 2-year prospective study carried out at five European centers show that the Akreos MI60 microincision IOL is easy to implant, is stable in the bag, has a low posterior capsular opacification rate and provides optimal visual quality.

A total of 125 patients were implanted with the Akreos MI60 microincision IOL (Bausch & Lomb), and 113 have reached 1 year of follow-up. Surgery was carried out under topical anesthesia, and biaxial microincision cataract surgery was performed in all the cases through a 1.5-mm incision.

"Some stretching of the incision was seen after implantation of the lens, enlarging the size to 1.8 mm," Anders Behndig, MD, PhD, said here at the European Society of Cataract and Refractive Surgeons meeting.

Scheimpflug images showed a stable positioning of the lens, with tilt in the lower range of different IOL types, around 1°, and decentration comparable to that of other IOLs.

Visual outcomes were good, with 96% of the patients achieving 20/40 or better at 6 months. In a subgroup of 40 patients, wavefront analysis with the Zywave aberrometer showed that higher-order aberrations did not change over 1 year. Compared with historical data of the standard Akreos lens, the new model was shown to have fewer higher-order aberrations, probably due to the smaller incision, and less tilt.
