[Optical consequences of implantation of a negative intraocular lens in myopic patients].

The implantation of a concave intraocular lens (IOL) (Worst-Fechner Biconcave Lens) is a new method of correcting myopia. This paper describes how to compute the effective power of an IOL on the basis of corneal curvature and anterior chamber depth, i.e., which lens will neutralize a specific myopia. The authors also discuss the size of the retinal image of an eye corrected by an intraocular lens as compared to an eye corrected by a spectacle glass.
