A new anterior capsular opening: dumbbell opening--its efficacy in the human eye.
Using excised pig eyes and a human eye-bank eye, we demonstrated the efficacy of our new anterior capsular opening, the dumbbell opening, especially for the human eye. The opening consists of two microcircular holes made by an automated electric microtrephine, connected by a straight cut made with scissors. The 3.5-mm-long dumbbell opening fully retained its original shape after cataract removal and posterior-chamber intraocular lens insertion.
