BERLIN — In cases with predictable refraction, secondary piggyback lens implantation into the ciliary sulcus is safe and effective, according to a small study.

H. Häberle and colleagues here implanted a secondary posterior chamber lens into the ciliary sulcus of eight patients. All patients had a mean disturbing anisometropia of +4.57 D and had undergone cataract surgery between 1 and 13 years previously. Piggyback lens implantation was combined with surgical aspiration of the secondary cataract in three patients. Postoperative anisometropia was reduced to a mean of +1.1 D. Elevated intraocular pressure or secondary cataract formation in the lens interface were not observed. One patient developed pigment dispersion.

The study is published in the February issue of Der Ophthalmologe.
