Abstract

• A new goniolens, called the "trabeculens," provides ×1.6 magnification and enhanced resolution of the trabecular meshwork by means of a new optical system that consists of a 30-diopter convex contact lens, hollow funnel, and four mirrors set at 62° angles to one another. The trabeculens can also be used for laser trabeculoplasty, with the addition of an indentor, and for laser iridectomy, with the addition of a 20-diopter planoconvex button lens.
