STOCKHOLM, Sweden — Three microincision lenses, combined with small-incision surgery, produced results similar to refractive surgery for reduced astigmatism and minimally induced aberrations, according to a study presented at the European Society of Cataract and Refractive Surgeons meeting.

Danielle Deidier, MD, prospectively looked at 400 eyes: 300 implanted with the Akreos MI60 (Bausch & Lomb), 50 implanted with the Microslim (Physiol) and 50 implanted with the Quatrix (Corneal). The hydrophilic acrylic IOLs were inserted through a 1.7-mm corneal incision.

In addition to low levels of induced astigmatism, low aberrations and stability in the capsular bag, the lenses had good best corrected visual acuity at 3 months, with the Akreos at 0.93, the Microslim at 0.98 and the Quatrix at 0.88, she said.

"This study demonstrated the smaller incision site provides excellent patient outcomes," Dr. Deidier said. "These new IOLs available on the market provide stability over time, as well as reproducible and efficient injection."
