LONDON — A new IOL for femtosecond laser-assisted cataract surgery provided higher predictability, refractive precision and stability, according to a speaker here.

Ludger Hanneken, MD, shared his experience utilizing the Lentis LaserLens (Oculentis) compared with traditional IOLs with colleagues at the European Society of Cataract and Refractive Surgeons Congress.

“With the new lens, the concept is to be implanted in the capsular bag then locked by the edges of the capsulotomy. The precise execution with predictable size and position of capsulotomy is necessary, but only possible with [femtosecond laser] assistance,” Hanneken said during a free paper session. “This locked position may minimize decentration, tilt and rotation. Higher predictability, refractive precision and stability is expected.”

Hanneken said he has implanted three of the lenses. Thus far, there have been no intraoperative complications and no instances of capsulorrhexis tearing.

Only a short additional time was needed for haptic positioning in capsulotomy; however, there is a short learning curve, according to Hanneken.

Moreover, there were no postoperative complications.

The new IOL is currently being assessed in an open-labeled, prospective, international, multicenter study at the University of Heidelberg. The study will include a patient follow-up of 12 months in 180 patients between the ages of 50 and 90 years with senile cataract in both eyes.

The primary endpoint is IOL decentration, and the key secondary endpoints are IOL rotation, IOL tilt, best corrected distance visual acuity, distance between the iris and IOL, and subjective refraction. – by Samantha Costa
