title: Lens holder and modified contact lens for pars plana vitrectomy.
abstract: A sustained-grip, pressure-release, cross-action forceps was developed to obtain firm and steady holding of the contact lens during vitrectomy surgery. For use in conjunction with the forceps, a plano-concave fundus contact lens has been modified by having a circular groove cut around it.
