Abstract
A goniolens is defined as an oblique-truncated cylinder. The base of the cylinder has a concave surface to ensure complete contact thereof with the cornea of the eye. The truncated surface of the cylinder is convex and its curvature radius is equal to 8.5 mm. The angle confined by a planes of the concave and convex surfaces ranges from 20.degree. to 60.degree., which makes it possible to focus the laser beam in the corner of the anterior segment of the eye during laser goniopuncture.
