STOCKHOLM, Sweden — The “behind-the-lens” technique for removing Healon5 during cataract surgery is safer and more effective than the "rock ’n’ roll" technique, according to a study.

Researchers here with St. Erik’s Eye Hospital randomized 159 patients undergoing cataract surgery to one of two viscoelastic removal techniques — behind-the-lens or rock ’n’ roll. Mean intraocular pressure preoperatively was about the same in both groups.

Five hours postoperatively, mean IOP had risen to 25.6 mm Hg in the rock 'n’ roll group and to 22.4 mm Hg in the behind-the-lens group. By 24 hours postop, mean IOP had returned to preop levels in both groups. Mean removal time of Healon5 (sodium hyaluronate 2.3%, Pharmacia) was 50 seconds in the rock ’n’ roll group and 39 seconds in the behind-the-lens group.

The study is published in the September issue of Journal of Cataract & Refractive Surgery.
