[BASIC-Program for calculation of intraocular lens refracting power].

The intraocular power of various types of lenses was calculated, based on different anterior chamber depths. If the lens type planned is changed, the lens power also must be altered, therefore, it is necessary to know the individual difference in diopters. For this purpose, a special computer program in BASIC is introduced, in which there is a table that shows the refraction after implantation of different types of lenses. Possibilities for altering this program are also shown.
